Title: Vintage Rubber Dome Keyboards
Post by: EscapeVelocity on Sat, 06 June 2015, 18:49:22
Hello, Im gonna discuss some of the more highly regarded (and widely available) vintage rubber dome keyboards in this thread.  I look forward to your comments, corrections, observations.


(http://i302.photobucket.com/albums/nn88/EscapeVelo/IMG_0044%20-%20Copy.jpg)

Today I received...

Brand New in Box Dell QuietKey RT7DJTW PS/2 keyboard   Made in Thailand (by NMB) late production model.

Used in Box IBM KB-8923 PS/2 keyboard. Made in Thailand 1996.

The IBM weighs a bit more than the Dell, but the Dell doesnt feel lightweight or cheap.


Dell QuietKey RT7DJTW

Firmer more tactile keypress
Darker toned gray keys (I slightly prefer this to the IBM)
Laser etched key caps are not as dark as the IBMs dye sub. (I prefer the IBMs greater contrast for easier visibility)
Keys have more pronounced pebbled finish than the IBM  (I prefer the feel of the IBM's smoother key cap tops)
Keys bottom out more harshly than the IBM perhaps due to newness and/or the lighter weighting/less tactility of the IBMs keypress itself.
Keys are all top printed legends (IBM has some side printed caps for 2nd function)
Bottom row has equally sized Control-Alt-Windows-Function keys with convex tops. (I prefer the IBM)
Caps Lock key drops off early producing a space between it and the A key which I like. (Both units have this)

IBM KB-8923

Lighter more linear feeling keypress. Feels easier on the fingertips almost pleasant. (I slightly prefer the IBM)
Lighter toned gray keys
Dye Sublimation printed keycaps which are darker and more easily read with higher contrast (helped by lighter colored darker grey keys)
Smoother key cap finish (I prefer the feel of these to the Dell)
Top row function keys are not two toned 4x4 color coded (I prefer the Dell)
Break and SysReq printed on side of key cap on the Pause and Print Screen button respectively (Nicer than the Dell)
Bottom Row has regular style concave curved key caps with larger Control key caps compared to the Windows/Alt/Function keys. (I prefer this to the Dell)
Caps Lock key drops off early producing a space between it and the A key which I like.  (Both units have this)


I like the cable management of the IBM slightly better but they are both functional and similar. The Dell has two level adjustable fold out feet, though the IBM is wider and sturdier.  The Dell has purple color coded usb plug, IBM's is grey. The Dell has bigger rubber feet on the front, and the IBM has no rubber feet on the back edge, while the Dell has small round rubber feet towards the back edge.

Dell on the top, IBM on the bottom.

Sideviews.  Dell QuietKey on the Left, IBM on the Right.

IBM Control/Alt/Windows/Function keys. Here you can see the crisp high contrast legends on the IBM key caps...as well as the larger sized Control key and the concave key tops. The Space Bar is slightly smaller than the Dell to accommodate the larger Control keys.

(http://i302.photobucket.com/albums/nn88/EscapeVelo/IMG_0045%20-%20Copy.jpg)

Dell Control/Alt/Windows/Function keys. Here you can see the lower contrast legends on the Dell key caps...as well as the convex key tops of this row of keys, and all these keys are the same size on the Dell.

Im kind of unsure as to the proper terminology rubber dome or membrane for these keyboards.

Anyways overall I like the IBM KB 8923 better.  However I wouldnt complain too much about the Dell QuietKey RT7DJTW.

PS Sorry about some of the pics, Ill have to retake some.

The IBM is also available in black, and swapping keys with cases looks good - either way.

Im a big fan of the Two Tone layout as seen on the Dell QuietKey.  Wish the IBM had the same full two tone layout. But it's nice to know that the IBM comes in black for those who are matching their system or work environment.  I find Black keyboards more difficult to see clearly though I mostly touch type, it comes in handy when searching for lessor used keys.  I like LED backlighting on black keyboards to offset this minor issue.

I wonder if the IBM are double shot key caps. I just assumed they were Dye Sublimation. I know what laser etching looks like and the Dell Quietkey almost certainly is laser etched.
Title: Re: Vintage Rubber Dome Keyboards
Post by: fohat.digs on Sun, 07 June 2015, 17:22:17
To see whether a plastic piece is a "multiple-shot" fabrication, just look at the underside and you will see evidence of the layers involved.

I have the IBM and the Dell, and both have ABS caps (acetone test). The Dells are lasered, but the IBM's legends look particularly crisp and nice, with the texture continuous across the legend and the face. If ABS can be dye-subbed, then these might well have been done that way.
Title: Re: Vintage Rubber Dome Keyboards
Post by: EscapeVelocity on Sun, 07 June 2015, 19:54:14
From wikipedia..

ABS keys is the prefered plastic to double-shot molding. That is because most other plastics shrink too much in the moulding process. Legends on ABS keys can also be pad-printed, laser-etched (burned) or laser-engraved (with or without infill). Because of the low shrinkage, some keyboards have space bars made of ABS even if other keys are made of PBT or POM.

So Ive been doing some type testing on some keyboards I own.

The Dell QuietKey RT7DJTW requires more force than the IBM KB-8923 and the Dell is also definitely quieter. The feedback is excellent on the Dell.

The IBM has a closer feel to the Cherry & Kailh Blues that I have.  It's key depress force is lower than the Dells. Also the IBM KB-8923 is quieter than the Cherry & Kailh Blues.

I think over all I like the IBM KB-8923 better than the Dell Quietkey RT7DJTW. But they are both nice. Kudos to Dell for delivering on their "QuietKey" branding/advertising.

I think I like the Kailh Blues on the Thermaltake Tt Sport Poseidon ZX (Tenkeyless) slightly better than the Cherry MX Blues on the KBT Race II 75% keyboard. But they are both nice.

So I rate the keyboards I have here like this based entirely on typing feel.

Thermaltake Poseidon
KBT Race II
IBM 8923
Dell Quietkey RT7DJTW

The Saitek Eclipse I that I was using before is just sad in comparison to any of these.

I'm somewhat interested in trying one, but not enough to buy one.

Since you're comparing to other boards, you need to try some non-cherry mechanical.

Post by: Blaise170 on Mon, 08 June 2015, 01:29:27
I will potentially have a membrane board coming in soon, though I'm hoping for Alps since the only other board I found with the same P/N had Alps. I'll share my experience with it when it does.

I wonder why it wasnt common to have rubber dampeners to cushion where the key caps bottom out.  That seems like a good strategy. I think the Apple Extended Keyboard II uses dampeners. Ill know soon enough.

These Alps Blacks in this new Dell AT101W 1999 (Mexico) are smooth as butter.  The keyboard is pretty big, but not huge.

What was the latest date the Dell AT101W was produced?  Latest date Ive seen is 2001 (by chance).

These Mexican produced ones are supposed to be built a bit tighter than the Malaysian made Silitek versions.

The Ivory and White Alps ones, which are the most common, have rubber dampeners, yeah. Some versions came with Salmon Alps, though.

Possibly. Mine is from 2001 too.

I can confirm that there are two different types of SKCM Blacks. The ones in my AT101W (from Malaysia) feel and sound considerably inferior to the ones in my old-logo AT101. It's possible that the Mexico-produced versions of the AT101W use the same, older SKCM Black switches.

The rubber dampeners in the Apple keyboards were there to quiet the switch, not the keycap. Keycap dampening is done by o rings.
Title: Re: Vintage Rubber Dome Keyboards
Post by: fohat.digs on Mon, 08 June 2015, 20:40:37
I have never seen an AT101 with salmon Alps (nor an AEK2 for that matter) although I have heard that they exist.

I have owned 2 old logo AT101s and both were garbage blacks with ABS key caps.

An AEK2 with pink/salmon will almost surely be the 1989 copyright, the 1990 copyright will probably be cream, and the 1995 copyright will likely be white, based on my personal observations.

No, o-rings is what cherry users resort to because their switches are completely incapable of doing the same thing. The internal rubber dampeners dampen in both directions downstroke and upstroke.

I realize the Del AT101W isnt a Vintage Rubber Dome, but Im just keeping my stuff contained as much as possible in this thread.

Anyways the Dell AT101W came with a 3 year warranty as noted in the box with my new unit. Pretty sweet!  Why didnt Dell continue to produce this model or something similar with Alps switches into USB after the turn of the century. For shame!

They were still being made after 2000, although it would appear for not very long. As for the USB thing; PS/2 is superior to USB. Also, it probably didn't help that Alps had been phasing out their switches for a while at the time :p .

I thought the old logo AT101 had Salmon Alps?
The Alps-made ones did, the Silitek-made ones don't. Easily distinguishable by FCC ID (GYI v GYU).

I have never seen an AT101 with salmon Alps (nor an AEK2 for that matter) although I have heard that they exist.

They sure do, I have a rather broken one in one of my videos here:

Are your old-logo ones the more common GYUM97SK then? Because I compared mine to the new-logo one and they feel and sound very different. I made a quick typing comparison here:

Yeah man. They start out really stiffish so lots of life in those keyboards.  They are a top rubber dome.  Save them and give them out or distribute them on eBay for a few bucks.

I don't even see the completed listing. But that is a really good price for it. Since you're apparently immediately delving into vintage stuff, I'll say: be careful, because you may find yourself not using cherry anymore. I got my first cherry at the same time as my first space invader, and I never ended up using the cherry even though it was brand new and the SI was covered with a carpet of lint when I got it.


@smeckledorfed
That is generally a good idea. Even if you don't someone else might. Better than the landfill at the very least.
Title: Re: Vintage Rubber Dome Keyboards
Post by: Blaise170 on Tue, 09 June 2015, 23:59:02
I will also say to be careful scooping up vintage. I've been burned on more than one occasion where I thought something was mechanical but it turned out to be even worse than rubber dome (the Keytronic Foam and Foil board I own... ick).

Here we go!  A new champion!

NMB RT6856TW

Pics coming soon.

Thanks! How does it compare to your NMB RT6856TW in terms of feel and sound? I imagine pretty similar since both are NMB rubber domes? Do you have a preference of the two? My only experience is the RT6656TW, so far.

Just a note. There are RT6656TW and RT6856TW models. I have the RT6856TW and it just came in today.

Judging by the weight the RT6856TW has a steel base plate which is nice. The Dell may not have one as it's noticeably lighter than the IBM 8923 and the NMB RT6856TW.

Im gonna say I like the NMB RT6856TW better than both the Dell Quietkey and the IBM 8923. This is why.

I like the smoother keycaps of the IBM & NMB. They fell better. The NMB RT6856TW being slightly more textured than the IBM 8923...and the Dell being much more textured than both of them.

The IBM KB-8923 feels a bit spongey-er than the Dell RT7D5JTW and the NMB RT6856TW when bottoming out the keys. The NMB and the Dell have very similar tactility in their key depresses. Maybe using the same or similar parts as they are both made by NMB (in Thailand).

So in my limited experience, I would say the NMB fixes what I found slightly annoying on the Dell QuietKey and also has better build quality with the metal base plate.

One more thing the NMB here has a more pronounced curve of the from bottom row to top row looking at the keyboard from the side than either the Dell Quiet Key or the IBM 8923. The Dell has a flatter case than the IBM but the keys have similar mild curvature to the IBM, maybe just a tad less.

Also of note is that the bottom row Control/Alt/Windows/Fn keys are normal concave key caps on the NMB (and IBM) while the dell has convex key caps which match the profile of the space bar. I prefer the normal concave style key caps.

The space bar on the NMB RT6856TW is a bit more squarish on the edge than the Dell...with the IBM 8923 in between. I like the more rounded space bar.

I like the NMB RT6856TW better than both the Dell QuietKey RT7D5JTW and the IBM-8923. But I could use any of them without complaint.

What I like about the NMB RT6856TW over the Dell QuietKey RT7D5JTW...

1. Less rough surface texture on the top of the keys.
2. More curved (rising from bottom row to top row) profile
3. Bottom row keycaps are standard concave instead of the Dell's convex.
4. Weighs more, indicating a metal base plate.
5. Key legends are a bit more contrasty and thus easily read (but the IBM trumps both here)

What I like about the Dell QuietKey RT7D5JTW over the NMB RT6856TW

1. Space bar is more rounded. NMB has a more squarish edge.  (with IBM in between)

What I like about both the Dell & the NMB

1. Tactility of the key depress is good (and very similar)
2. Dual colored Pearl & Pebble IBM M style key layout


Hope that helps.

PS- I wonder what the difference is between the RT6656TW and the RT6856TW, maybe the same keyboard but the 66 version ditched the metal base plate to save costs?

Do you think it would be hard to get back together? I suppose there's no way of knowing without doing it for domes. I had one that I opened once before I got any mechs and the keys and stuff went everywhere. Though the fact that that one even has a slider means it is a much better design anyway than that one.

So the Acer Accufeel 6311-TW semi-mechanical membrane is coming, but apparently this doesnt qualify as a rubber dome.

Also a mid 00s Dell KB 1421 USB is coming this week.

I also have a KeyTronic LifeTime Classic (Made in Mexico PS/2) coming.

Im gonna try to pick up another Made in USA Keytronic in it's traditional design. And maybe a Designer as well. 

Plus a Chicony 5923 or 6923 and that will do it for my Rubber Dome round up. 

Considering a BTC 5339 as well.

Any recommendations on a Maxi-Switch keyboard?  The Gateways are mostly Maxi keyboards.

Title: Re: Vintage Rubber Dome Keyboards
Post by: fohat.digs on Mon, 15 June 2015, 10:07:28
Gateway2000 AnyKey series

These are desirable and sought after by certain people, if they have the extra programmable keys.

Gateway2000 AnyKey series

These are desirable and sought after by certain people, if they have the extra programmable keys.

As I remember, they have MX-compatible caps, but the entire board might fetch $25-$35 + shipping on ebay.

Mine does not have MX-compatible keys, it is basically just rubber dome mount. Some of the Maxi do, others do not.

All MaxiSwitch keyboards that I've seen had either Alps mount, or sliders joint with keycaps. For example, the SK-6000 (my favorite MS Natural-like keyboard) or SK-710W.

That's weird. My AnyKey has a red membrane under each switch and square pegs. The label matches up to the model and it has Maxi switch on the label.

AFAIK MaxiSwitch was (eventually?) a subsidiary of LiteOn, which eventually merged with Silitek. Some changes could happen over time. But the Alps/no mount is my experience anyway.

My quietest keyboard by far is the Dell KB-1421. It's a decent little keyboard, though a bit mushy with short key travel. So meh. This is a QuietKey keyboard though it's not prominently advertised.

The Dell QuietKey RT7D5JTW is the 2nd quietest keyboard I have, then another jump to the IBM KB-8923.  Then the Chicony KB-5181 with Monterey switches followed closely by the Dell AT-101W.  The rest are loud as all get out including the NMB RT6856TW that I was praising (also the Chicony KB-5191 w/Futaba)

Nice to see someone liking the membrane squad instead of the usual CherryMX suspects here on GH  :thumb: .

YES the IBM KB-8923 is the BEST of that bunch especially the way it was constructed and presented.  If they ever bothered to make a single SSK like model that would easily start a new cult like status as their older buckling spring brothers did.

Now that Ive spent some time with the Dell KB-1421 rubber dome keyboard. Im revising my assessment of it.  It's got some good feed back and key stroke throw while shortened is still within the realm of traditional. The landing is soft, and the larger keys are well stabilized.  All keys likewise have good response in extremely off center key punhces. They dont rock so much and bind but only slighly rock and ride downwards. The keyboard is very quiet, one of the quietest keyboards Ive ever heard. 

I really like the no nonsense styling as well. It's about as small as a standard keyboard can get and also very slim. It has a nice heft to it as well indicating the presence of a metal base plate. The heft helps give the keyboard a solid feeling & stable platform for typing. Rubber feet and flip out risers on the backside. The USB cable is firmly connected at the center of the backside as well, but with no cable management.  You could do a lot worse worse than the Dell KB-1421.

Dell KB-1421 circa late 2000s. These shipped with Dell Optiplex systems.

My latest acquisition is a newer key board from the mid 00s, around 2005 or so.

Logitech UltraX Premium Slim PS/2

These were made in both PS/2 & USB versions. The USB versions are impossible to find. New in Box PS/2 versions are sporadically available on eBay. 

Short key travel rubber dome (maybe around 2mm). The keys are very stable with smooth key response on off center strikes. You can see this in the video. I really like this key board. A great alternative to the Logitech DiNovo Edge (and Logitech K740 Illuminated).  The keys themselves feel great with a slightly pebbled surface texture, they are flatter than standard keys being slightly curved but comfortable none the less. The keystroke gives excellent crisp tactility.  I dont like that Function Row keys are smaller, especially the Esc key...but they use the same materials and rubber domes for actuation...which feels good.

The rubber dome protrudes upwards in a nipple and depressing this nipple with the flat underside of the key actuates the stroke. The keys are held on with 4 small plastic clips around the edge of the white plastic.

As you can see the keyboard is very slim. There is no cable management and the flip out risers on the back feel flimsly, could be more substantial IMO. However having said that, laying flat it's planted firmly and the keyboard body feels solid, it doesnt creek, and only a small amount of flex when grabbed at both ends and twisted. It's got a little heft to it for it's small size.

There is a lot of love for this keyboard out there from it's users.  Apparently the space bar is prone to failure at about 10 years of use.

EscapeVelocity (or anyone here), ever get to use a Dell AT101R? Found it at my local thrift store and was quite disappointed to see the "R" label - thought I found a genuine AT101. It's quite nice for a rubber dome though. Knowing my luck, it'll still be there since it's a rubber dome, maybe I'll go play with it after work.

...but not as nice as the Fellowes-Microban Split Ergonomic!  :p

Ill post up the KeyTronic LifeTime Series Classic (made in Mexico) next.  One interesting thing about it is it's the highest force key depress keyboard I own.  They brag on the box about it being able to withstand 20 g's and still be operational (Saturn Rocket). Maybe that has something to do with it.

It's my least favorite of the Rubber Domes so far, including the Dell KB-1421.

It's whisper quiet though. One of the quietest of the bunch.

Microsoft doesn't produce keyboards; they order them from actual OEMs. For example, the early MS Natural was made by Key Tronic (e.g., CIGE03786).

KeyTronic LifeTime Series Classic PS/2 (Made in Mexico)

The KeyTronic LifeTime Series Classic II is made in China. Should be the same keyboard & build quality.  I dont think you gain anything from looking for the Mexican made version.  Made in China Classic II is much easier to find (New in Box)

Pros

Build Quality is good, no creaking, some flex in twist test
Very quiet typing
Big Ass Enter Key w/Large Backspace and good compromise on Right Shift
Flip Out risers are very sturdy and grippy
Key feel is great with pleasing textured surface
Keys are well stablized. Off center strikes are smooth & quiet.
Good tactility to the key stroke.

Cons

Bottom of keyboard is not smooth & flat, structural diagnol plastic ribbing
Lack of two tone key set, I prefer grey & white
No cable management
Contrast on the legends isnt the best Ive seen

Neutral

85g force for key depress, I didnt find this to be a problem. Could be for some.
Pretty lightweight, no metal backplate.


This is my least favorite keyboard of the Rubber Dome bunch here. That being said, it isnt a bad keyboard, and I could be happy enough using it (but I dont have to). It's a good keyboard overall. I really like the Big Ass Enter configuration and the flip out feet are some of the best Ive encountered, very solid, positive click set, with grippy rubber on the ends.

The 85g force for a keypress is the highest Ive come across on the boards Ive assessed here. This is getting to the upper level of the classic research done by IBM on key weighting.  I think I prefer this to the IBM 8923 which tested the lowest force of just under 50g, but Im a heavy handed typer.

It's just a couple of little annoyances that I dont have to live with, like the lack of dual color keys and the ribbing underneath which is uncomfortable for lapping the keyboard.

KeyTronic claims tested to 20 million strokes & made to withstand 20g force and still function.

Nice one!  Not many people appreciate a rubber dome anymore.

I dont care for the ones with all the media keys and stuff. Just straight IBM Model M style ANSI.

There are only a couple of more Im gunning for. A Chicony 5923/6923 and possibly a couple of Compaqs one being the RT101. Im curious about Maxi keyboards though. You dont see to many of them outside of Gateway.

I think the nicest I've used is probably the Logitech G105 I used to have. The backlighting was nice but then I dove head first into mechanical keyboards and haven't looked back. I personally find that Brown Cherries feel like rubber dome and Topre (which is technically rubber dome) feels overall "meh". It has a nice feel to it, but not worth anywhere near the $200 most of them go for.

I had a Compaq (I think it was numbered SK2800 but I may be wrong) with rubberized media keys and I really liked it. I think they called it the "internet keyboard" and it was made in the very early 2000s. I used one for several years and even bought a couple of backups when I found them cheap or free, but after I got back into mechanicals about 5 years ago and started using keyboard shortcuts extensively, I left them behind.

I still love "rubbery" key caps for certain keys, but they can't wear well for often-used keys.

ps - if you get one of these you will have to find a driver to wake up the extra keys. I think I still have it if you can't find it.

KeyTronic E03601E made in June 1992 branded Target. Looks like a EuroTech/Designer model.  Has the nice flip out feet of the LifeTime Series Classic, plus some of the plastic structural ribbing on the underside.  No cable management. Body rises on the backside giving height to the Function keys as it rises from bottom row to top row.

Very quiet keyboard. Similar design to the key actuation as the LifeTime Classic above. Big Ass Enter key with small Backspace. The Eurotech & Designer models offer Big Ass Enter and One Row Enter variations.  Not much flex in the twist test and not much creaking. Stabilization of the larger keys is OK but Ive seen better.  The keys feel good with a pleasant texture and crisp high contrast legends. Good tactility to the key depress. Seems like a higher force key depress like the LifeTime Classic, though I havent given it the nickel test.

It's an OK keyboard.

Pics coming soon...

So Ive been trying out the Topre Clone 40g Noppoo EC108 Pro and it's definitely a good keyboard. I probably would like a bit more key press force in the spings.

Of the Rubber Domes I have on hand, the Noppoo Topre Clone 40g surpasses most on key feel. excepting the NMB RT6866W, which I prefer. The NMB RT6866W doesnt have a mushy bottom and springs back quickly. Feels very similar to the Noppoo, however it's much noisier than the Noppoo. Right behind the Noppoo I would rank the Logitech UltraX Premium, however the UltraX has shortened keystroke and flattish keys, which might be disliked by some, however the switch feel is fantastic. Next I would place the Dell QuietKey RT7D5JTW right behind the Noppoo as well, but with mushy bottom out...and the Dell KB-1421 which also has a mushy bottom out. Then the IBM 8923, which has mushy bottom outs and lacks in tactility combined with low force switches. 

The Noppoo lacks tactility as well and is a light force switch. But the lack of mush at the bottom combined with the quick key return great.  Definitely usable. The 55g version is probably the way to go. Ill probably be selling mine in the near future. It's just not that much "better" than some of these others, and I straight out prefer the NMB RT6866W (cept for noise) to the Noppoo 40g Topre Clone. The Dell QuietKey RT7D5JTW is right there as well (and it's quiet) but with a mushier bottom out.

Here is a pic of my Noppoo EC108 Pro w 40g (45g) Topre Clones with MX Stems...below my Dell KB-1421. They have similar profiles, but the Noppoo is slightly heavier and has a detachable USB cable with bottom cable management...plus 4 extra media keys.

One minor aesthetic dislike about the Noppoo is the highly polished chrome/silver surface shining from between the keys, this might be helpful in use in a dark room with lights from the monitor only, though. Havent checked that out yet.

One of the things I like about the Noppoo Torpre is that it is very stable key depress, it isnt wobbly. The IBM 8923 is bad with this. The NMB RT6866TW and Dell QuietKey RT7D5JTW also have very stable key depresses...as does the Logitech UltraX.

I'd bet this is because all of these keyboards (not the IBM) have much larger domes, providing the stability you like.

Well, Im not sure about the physics of rubber domes. I guess I never thought about that. Always assumed the plunger/stem system was more important to that attribute.  But now that you mention it, seems like that might contribute as well.

KeyTronic LifeTime Series Classic PS/2 (Made in Mexico)

I found a true KeyTronic Classic AT keyboard as I was moving all my things...

I had to clean it up a bit, I haven't even tested it yet, I know I have some AT-PS/2 adapter somewhere around here, but everything is still in boxes and I have to dig through a lot to find one.  I'm sure the keyboard works 100%
I'll follow up when I find an adapter here... somewhere...

My Chicony KB-5923 is Made in Thailand with an AT style plug but with Windows 95 keys.  It's branded US Logic and seems to have been made for Computer City retail chain (a division of Tandy Corp)

Anyways it seems to be a cheapened down version from the NEC and Digital branded Chicony KB-5923s that I ive been eyeballing.

The case seems to be cheaper, specifically the cable management channeling and the keycaps are simply pad printed. Im fairly disappointed in this purchase.

My Massdrop Keycool Hero 104 RGB came in yesterday!

What a light show!

All in all I think I just prefer a single LED color in Green or Amber(Orange).

I do like the function where the keys light up as they are depressed and shine for a short time then fade.  But dont anticipate using it much.

The other color that I really like on this keyboard is the shadings of blue that can be paused upon. You can get a nice medium skyish blue going. Looks real nice.

As to the rest meh. You can pause the color on orange and green as well. Which is nice.

I really dont care for the Font on the keys though, some futuristic looking thing kind of like on the CoolerMaster Quickfire Storms.

I do like the white key caps backlit as well. Better than blacks IMO.

The Kailh Blacks are nice, give a good amount of resistance (I dont care for the lower force swtiches like Cherry MX Reds)

Build quality is very nice. Not sure if Im excited about the braided cord or not. Meh.

I like the feel of the Kailh blacks better than the 40g Topre clones on the Noppoo EC108 Pro...which are too light for my tastes with barely perceptable tactility.

I have Kaihl Blue keyboard the Thermaltake Tt Sport Poseidon ZX tenkeyless model...which I like. Dont care for the Blue LED backlighting on this one so much and the LEDs are really bright. I keep it on the lowest brightness setting of the 4 available.

BTW, EscapeVelocity, while we really appreciate your starting this interesting topic, do you realize how hard it is to find details about particular boards—from a search engine, GH's Search box, or using Find on the page itself—with extensive KB-list signatures like yours peppering the site? I'm sure we'll all quite impressed with how many boards you've managed to accumulate, but how often do you think we need to be reminded?

I found a true KeyTronic Classic AT keyboard as I was moving all my things...

Ah, memories... My first-ever PC clone came with a keyboard that looked just like that, except it was PS/2. Just like yours, it was unbranded except for the bottom label. Windows 98 was brand new at the time. It got thrown out in a move. I never thought to write the model number down, because at the time, I was under the false impression that all rubber domes were bad just by virtue of being rubber domes. Since then I've used some truly bad boards that have made me pine for it. It was before they got into Ergoforce or other such gimmicks. Hopefully I'll find one some day.

I found a very interesting vintage rubber dome at my Goodwill yesterday, the Manhattan True-Touch keyboard. It has one-piece caps with an extremely long stem which makes key presses nice and tactile; I'd argue the Dell Quietkeys are still better overall.

BUT, the best thing about this board is the layout, I think it's ISO but it's an ISO layout I can actually tolerate (normal size backspace and 1.25u left shift and small right shift). This is the best/closest picture I can find online:

(http://www.suntekpc.com/image/kb-uh2-mht-detail.jpg)

I hope it's still there next time I go - I forgot to bring my phone yesterday when I went. I almost bought it b/c of the layout but $3 for a rubber dome...meh

I forgot to follow up on this post.  I found the AT to PS/2 adapter and the keyboard works just fine.  I'm typing on it now, and it's better than a lot of other rubberdome keyboards I have used.  I would call it heavier than others I have used.
All in all, it's a nice keyboard for what it is.

The Packard Bell 5131 I posted earlier on this page looks like a rebrand, except all of the keys in that photo have individual domes, not just modifiers. They look smaller too, I don't see much room for DIY. The additional symbol keys are neat though, I'm only used to seeing those on high-end boards like the Hi-Pro or the HHKB Pro JP.

I'd like to add my two nominations for excellent RD boards:
  • The HP C3758 / C3758A. Here's a recent GH thread (https://geekhack.org/index.php?topic=48699) on them. Built by Key Tronic but designed by HP, their full-travel, tactile keys feel as close to a Topre as any non-Topre I've used. New ones can still be found for $20–25. It's a lot of KB for so little dough.
  • One of the Lexmark-made "quiet" IBM Model M's (p/n's 70G8638, 71G4643, 71G4644). They're often overlooked because of the inevitable comparison to their great buckling-spring counterparts. But they're still Model M's, and many feel they're the best RDs ever made.

Several questions:

How would you compare the Lexmark M rubber domes to the HP 3758/A?  Do you prefer one over the other?

Do the Lexmark M membrane keyboards also suffer from broken plastic rivets?

I decided to take my Digital LK46W-A2 into work to use for a bit to see how it feels.
[attach=1]

[attach=2]

I acquired it NIB and shuddered at the thought of using it at home with kids around, so this is the only other place I can use it.

I took a photo of the serial # at an angle so the embossed printing could more easily been seen.

The LK series of boards are for OpenVMS and as you can see it is an ISO layout, so it makes it a little more interesting to use: placement of Ctrl, Find and Select are Home and End and Re-move is Del.
As yet I don't know if the Compose Character/Help/Do/F17-F20 have an equivalent function, so sometime I will find a program to see what they are outputting (if anything).

I was trying to find the years it was manufactured without much success.  I picked it up with a Digital Server 5000, which was the 'white box' equivalent of the Alphaserver 1200 and designed for Windows NT4 (source: https://en.wikipedia.org/wiki/AlphaServer (https://en.wikipedia.org/wiki/AlphaServer)).  The Alphaserver 1200 was release in 1994, so there is a pretty good chance that the LK46W-A2 started life then also (not necessarily this one though), right up to 2007 when they were discontinued.
(http://www.overclockers.com.au/pix/image.php?id=3xeq5&t=1)


So far has a nice feel: no wobbly keys and a nice firm linear feel, and most of all it doesn't feel mushy.

I've been saving up over a dozen vintage rubber dome keyboards so far, almost all of them dome with slider. I plan to do a dome with slider all in one review at some point. For me the one that stands out way above the rest is BTC conductive dome with slider over PCB (in short, BTC dome with slider). It's excellent, better than some mechanicals I have.

I actually have the Dell and a lot of those IBM ones since they came with all the Pentium Pro 200 systems I have.  I actually hated them and got a bunch of Ms for those systems.  Those systems never went to their original destination, but may soon enough if not 20 years late.

I have a few of the IBM rubber domes as well.  While I can't type as fast as I can on my M, they come a close second as my hands' favorite keyboard--and probably my favorite non-clicky.

Oh, I forgot that we bought a Keytronic when we built our 486 back in the early 1990s.  We still have it and it's a favorite of my hands too because of the lighter touch than the IBM rd.

Sorry to post to Ye Olde Thread, but a NIB Dell KB-1421 came in at the community recycling depot where I volunteer, and I managed to get it. (They know I'm the resident KB maniac and take pity on me.) I really like it!

What you notice right away is how compact it is—you won't find a thinner bezel on any board. And yet there's a heft to it, and the case is solid, with no flex. It looks and feels well-made, not cheap at all.

This is indeed a dome board, not a membrane (interior photo here (http://utensilia.tk/urzadzenia/dell_kb1421/6.jpg), courtesy of this Italian reviewer (http://utensilia.tk/txt/urzadzenia_en/dell_kb1421.htm)). I've found there are two kinds of RD boards: Those where you can really feel the domes, and those where you can't (usually because the domes are smaller). This falls into the 2nd category. But while it may not give you Topre-style thocky feedback, I think it's faster and more responsive as a result.

To me, it feels like a shorter-throw version of Cherry MX Reds. Just as smooth, with a decently satisfying "tick" when you bottom out, and no rattle or mushiness. Of course it won't last as long as an MX board—but considering you can get them new for around $15, it's hard to complain.

Alright, anyone mind helping me ID a keyboard I found a few weeks back? It's a Honeywell model no. "E03601ELHW-C". It's a full sized board, uses DIN5 connector, and is some weird ANSI/ISO mix where the enter is inverted ISO and the \| key is one half of where a regular ANSI backspace would be. I've never tried any high quality rubber-domes before, but I'm guessing that these would make the cut. They're extremely crisp and stiff, and the legends use a really nice font, with really nice geometrical, round letters. The windows logo is 98, I'll put some pictures up tomorrow. If I had to compare topre to a rubber dome, this would be the board I'd use in comparison.

In comparison with Topre, Topre boards have much lighter actuation, I would say that the actuation point is slightly higher on the Keytronic than Topre, and there's slightly more keycap wobble on the Keytronic than topre. Overall, Topre provides much smoother typing experience as the high actuation point and force of the Keytronic can prove quite jarring.

That's interesting that you mention lighter actuation as I find Keytronics much lighter than an M, probably on par with stock Cherry blues.  On the keycap wobble, it seems to vary as my original board has a lot more than the 'newer' one I have.

I'd have to rummage through my box of dome with slider boards back home to find out all of them, but from my recollection especially BTC and Monterey dome with slider stood out, they are really good. However, also NMB dome with slider, Olivetti rubber domes, and Bloomberg miniature domes were definitely better. Fujitsu Peerless would've been better if they used better stabilisers. Fujitsu dome with slider is mushy, but still better than Key Tronic. Even Key Tronic dome with slider was better than Key Tronic rubber domes, as I recall.

Pull off a cap. If you see a slider, it's dome with slider ;) .

KT mount is quite easy to recognise, too, it's like a little beam that's grabbed by two prongs in the keycap. You'll recognise them; they look a lot like their foam and foil switches.

I'd have to rummage through my box of dome with slider boards back home to find out all of them, but from my recollection especially BTC and Monterey dome with slider stood out, they are really good. However, also NMB dome with slider, Olivetti rubber domes, and Bloomberg miniature domes were definitely better. Fujitsu Peerless would've been better if they used better stabilisers. Fujitsu dome with slider is mushy, but still better than Key Tronic. Even Key Tronic dome with slider was better than Key Tronic rubber domes, as I recall.
Interesting.  How do I know if my Keytronics are just dome or dome and slider?
Pull off a cap. If you see a slider, it's dome with slider ;) .

KT mount is quite easy to recognise, too, it's like a little beam that's grabbed by two prongs in the keycap. You'll recognise them; they look a lot like their foam and foil switches.
I'll have to do that when I'm near them next and have my keycap puller with me.

Today I picked up a Microsoft Natural Keyboard from 1994. I found it randomly while thrift store hunting and was blown away that it can in the original box with all the documentation and even the floppy!

Not sure how rare these are, but I thought it would be worth sharing as this is the first year of the Natural models.

They're extremely common. I've run into dozens of MS Naturals at the recycling centre, but I've never seen a dome with slider model before Oo . Let alone with what appears to be Key Tronic mount.

So the first model of the Natural's were actually made by Key Tronic, hence the sliders. Apparently Key Tronic made some of the best rubber domes.

Also I learned this is actually the first keyboard that introduced the Windows and Menu keys as well.

All early MS Natural keyboards were made by Key Tronic, but some didn't have discrete sliders. The domes were way too stiff and not as nice as Key Tronic's own keyboard line.

So that's why my brother likes the original MS Natural the best--it had one of the best rubber domes at the heart of it.  :cool:

Could you imagine what would happen if Topre made a MS Natural shaped board?

I got one in the 1990s and tried to use it a couple of times but it was just too unnatural for me. Part of my problem is that I use "other" keyboards too and I get disoriented going back and forth.

From buying and selling a few of these on ebay I know that the originals with "inverted-T" arrows are much more desirable than the "+" layout that came later. There is also a Dell-re-branded variant which is no different from its MS contemporary.

That was my problem as well.  Plus, my 2-fingered typing style at the time had me 'reaching over' too much for the keys at 90 degree angles.  I probably would like it a lot more now.

Very interesting to know about the dell-re-brand.  I'll have to tell my brother about that little gem as he stockpiles the MS since the domes wear out after about 10 years of use for him.

That's interesting about the Dell rebranding. Did they use the Key Tronic mount with sliders as well?

I sold it on ebay years ago but I don't think so.

Sorry to post to Ye Olde Thread, but a NIB Dell KB-1421 came in at the community recycling depot where I volunteer... I really like it!

You have a BTC, right? How do they hold up to that? :)

Yes, I have barely-out-of-the-box examples of both within arm's reach.

Dell: Quiet, smooth, fast. Modern-looking (compact, flat key profile, black).

BTC: Much stiffer. Noisy, but in what most of us would consider a good way. More cylindrical buttons. Big-ass Enter (but both have normal Backspace). Retro-looking (1" bigger in every direction, curved profile, pearl).

Basically, we're talking vintage vs. contemporary. People into older boards would prefer the BTC. People who just want to type would go for the Dell.

Surprisingly, they weigh about the same. As far as I can tell, this is because—despite its small size—the Dell has a thicker case. They're both solid, well-made boards with no flex. The BTC's keys rattle a bit when shaken sideways, but that's probably because they're sliders over domes, which are bound to be more complicated.

I'm amazed something as solid and handy as a NIB Dell KB-1421 can be had for around $15 shipped. (Here are the ones currently on eBay (http://www.ebay.com/sch/i.html?_odkw=new+dell+kb-1421&_sop=15&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xnew+dell+kb-1421+-palmrest+-cover.TRS0&_nkw=new+dell+kb-1421+-palmrest+-cover&_sacat=0). As I write, there are two at $17.99 or Make Offer, free shipping.) It's loads better than the flimsy membrane boards they sell in big-box electronics stores. If you just want a compact, reliable board to take places where you might worry about an MK, it seems perfect.

I miss EscapeVelocity :(

Thanks!  What a nice thing to say!

Im back for round two!

I just got a Logitech G810 Orion Spectrum delievered today.

And I just purchased a Gigabyte Aivia Osmium with Brown switches.

Im selling the Ducky DK9087 tenkeyless with Cherry Blues and Green Backlighting.  And also the Keycool.   

I already sold the KBT Race II  with Cherry Blues and white LED backlighting, which I kind of regret. I really like the 75% 84 key form factor...but Im for quieter keyboards now.

Which means Im really kicking myself for selling the Nopoo 108, which was quiet and a joy to type on.  So Im probaby gonna look for another Topre ( or clone) board.

Oh and the ThermalTake Poseiden Z TKL has an issue. I might just salvage the Kaihl blues on that one.

Anyways good to see everyone.

Im gonna contact Chyros and send him a Logitech UltraX PS/2 board, brand new from mid 2000s for him to review (maybe trade for another vintage slider over dome keyboard from his collection.  He's made so many more videos since I was last looking into keyboards earnestly!  Wow!

Good to see everyone!

One thing I wanted to say is that the Chicony KB-5923 and the IBM KB-8923 use the same standard rubber domes.  The 8923 however weighs more and is a bit better on the underside construction and the keycaps are a bit nicer.

The keyfeel is the same on both. But I like the IBM KB-8923 better. That being said the Dell Quiet Key slider domes has a superior keyfeel to both.

I havent checked out the KB-6923, but I bet it's a step in between with the same standard rubber domes.  So I probably wont.

Currently sourcing a few more models. Ill let you know as I acquire them.

I'd like to add my two nominations for excellent RD boards:
  • The HP C3758 / C3758A. Here's a recent GH thread (https://geekhack.org/index.php?topic=48699) on them. Built by Key Tronic but designed by HP, their full-travel, tactile keys feel as close to a Topre as any non-Topre I've used. New ones can still be found for $20–25. It's a lot of KB for so little dough.
  • One of the Lexmark-made "quiet" IBM Model M's (p/n's 70G8638, 71G4643, 71G4644). They're often overlooked because of the inevitable comparison to their great buckling-spring counterparts. But they're still Model M's, and many feel they're the best RDs ever made.
BTW, EscapeVelocity, while we really appreciate your starting this interesting topic, do you realize how hard it is to find details about particular boards—from a search engine, GH's Search box, or using Find on the page itself—with extensive KB-list signatures like yours peppering the site? I'm sure we'll all quite impressed with how many boards you've managed to accumulate, but how often do you think we need to be reminded?

Oh OK, that list is more for my own use.  Ill make one post and just update that. Sorry. And thanks for the tips.
