Title: Suitable USB adapters for IBM Model M?
Post by: spremino on Thu, 16 June 2016, 09:08:29
[EDIT: It seems that the safest route is to buy a "Blue Cube" plus a short USB cable.]

I am looking for an USB adapter for an IBM Model M.  I know about the "Blue Cube" by Ziotek, but because of its dimensions, it might not fit in my laptop and in crowded USB hubs.  Therefore I am looking for an alternative, preferably available in my country (Italy).  Of the following adapters, is any known to work flawlessly with an IBM Model M?  Suggestions for other alternatives are also welcome.  Thanks.

There's nothing certain with the cheap Y adapters, especially when it comes to laptops which tend to be more finicky.

I'll second the idea of a bluecube and a short USB (which is what I use on my laptop).

You may want to roll the dice with a cheapo, you might get by fine.

The Blue Cube one is finnicky, straight from PS2 it works fine but when I try to convert AT > PS2 > USB it does not work properly and makes the keyboard entirely unusable.

AT>PS2 is just straight wiring, shouldn't impact the cube at all.  I've never had an instance where a bluecube didn't work for me and I've been using them almost since they were first available, on multiple different hardware.

orihalcon (Soarer) cable
SDL to USB, fully programmable
downside = expensive ($40 iirc)

you can find them on ebay

edit: it makes the keyboard hot-swappable too, eliminating that downside of PS/2.
elegant as Hypersphere put it, suits it

I can vouch for the Orihalcon cable as well. It is an elegant solution. I use one with my IBM SSK, and it works perfectly.

If you just want something plug and play, go with the Blue Cube. If you need something programmable, go with the $40 solution.

There is a guide online on mounting the guts of the blue cube inside the Model M.
This way no adapters show, no extra cables, etc... Just a clean setup.

This looks interesting, and something that I could attempt.  However:
- the adapter does not look firmly kept in place by what the author calls "creative soldering";
- one comment states that the mod didn't work on a 1993 model.

I can vouch for this one too - it work to get all sorts of keyboards working on various computers including my Mac.

I also have an orihalcon SDL to USB cable which is absolutely rock solid (using it with a full size Model M to type this via my Mac).

Hi guys.

Sorry to resurrect this old thread. I have three IBM Model M keyboards (p/n 1391401) and two PCs equipped with Asus Z97-K motherboards. I can (sadly) confirm that the Blue Cube doesn't work with these particular motherboards, and I wonder if this is the case with other Asus boards. I remember Soarer had developed an adaptor cable, but I never got around to buying one from him. Does anyone have any experience with these particular (and later) Asus boards and Soarer's SDL to USB cable?

Thank you.

I am looking for an USB adapter for an IBM Model M...

Sorry, but I must absolutely disagree! There are several reasons to get one of these cable-type keyboard/mouse converters instead:


(https://www.cablingsys.com/images/u04-ps2-01.jpg)


If you know that a Model M will be absolutely the only PS/2 keyboard you'll want to convert to USB, you can get a Blue Cube, and it'll work—if you don't mind spending more than you have to, and (probably) blocking one of your other USB ports.

Otherwise, trust me—get the cable type. Here's a handy search link (http://[url=https://www.ebay.com/sch/i.html?_odkw=ps%2F2+usb+keyboard+mouse+converter+-female+-male+-%22for+pc%22+-smart+-plug&_sop=15&_osacat=58058&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xps%2F2+usb+keyboard+mouse+converter+-female+-male+-%22for+pc%22+-smart+-plug+-adapter.TRS0&_nkw=ps%2F2+usb+keyboard+mouse+converter+-female+-male+-%22for+pc%22+-smart+-plug+-adapter&_sacat=58058) you can use to see a selection of them on eBay, arranged from lowest price to highest.

BTW, though "adapter" and "converter" are often used interchangeably, they actually have specific meanings:
Happy converting!

As mentioned on Clickykeyboards (http://clickykeyboards.com/product/ps2-to-usb-adapter-converter-for-keyboards-short-usb-cable/), most of those are cheap adapters, not converters.

orihalcon has a slightly more economic option that doesn't have soarer's functionality:

Nope! I'm a technical writer, dude; I know the difference between an adapter and a converter.

You'll notice the cable-type keyboard/mouse converters I linked to above have an electronic module in the middle that converts the signal—otherwise you'd see just straight cabling there. I've bought many of these for friends as well as myself, and they work great.

Maybe you just assumed that because they're so inexpensive, they had to be non-active adapters. Nope again! They're just a particularly good deal; that's why I've bothered to post about them here. (I've no doubt CK would prefer people buy their $16 KB-only converters to do the same thing [grin], but it's not necessary.)

I could care less if you graduated from MIT. The fact is, a lot of people who've tried the cheaper variety have reported issues getting them to work over the years. The Bluecube costs a bit more but has a long history of just working. I found that to be true in my case, as well.

I could really care less how cheap they are assuming they had a fairly consistent track record. Then again, if you're worried about spending $10 or $12 bucks for a quality component, you're probably in the wrong hobby anyway. The fact is, the cheaper variety simply do not work consistently. Further, Clickykeyboard's doesn't buy in large enough quantities to receive a discount on the Bluecube's they sell, so why would you or anyone else expect them to sell them at cost? No one's forcing anyone to buy them from CK, either.

Dude, you needn't be so defensive... You're free to do whatever you wish. I was simply contributing my experience—having used, and been pleased with, more of these converters than I can remember.

As far as I know, we're here not to lambast one another for sharing what we consider useful tips, but to try to advise and help and enjoy discussing KB stuff. (And no, I don't see any harm in mentioning one's technical background when discussing technical things—for example, to dispel the notion that one's naive about the diff between two basic types of devices.)

If you want to spend more on converters, that's great, knock yourself out. It certainly doesn't cost much to try one of these inexpensive ones, though.

And frankly, a $2–3 part doesn't seem worth all this controversy and fuss. But of course the Drumpf Age is upon us... It may now be stylish to become belligerent over even the smallest matters.  :?D

BTW, I think you meant you "couldn't care less". (If you could care less, you do care, as you could care less about it than you do.)

I'm not sure why people started using that phrase incompletely; it was probably just misheard and repeated that way.

In case you crave extra detail (you know how we KB peeps are into detail), here's a short video about it (https://www.merriam-webster.com/video/could-care-less-or-couldnt-care-less) at Merriam-Webster's site. It's presented by a babe with purple hair. Personally, I couldn't care less what colour her hair was, but there you go.

Actually, it's either / or, though caring less implies there was initially some degree of caring whereas 'couldn't care less' implies you literally cannot care any less. In this particular usage, I personally don't care whether you're a technical writer, and I could care less whether you graduated from MIT.

If all you wanted to do was relate your experience, you could've left it at "these have worked great for me and my friends". Rather, you made it sound like anyone who buys a Bluecube is basically overspending when, in essence, the cheaper alternatives work just as effectively. The fact is, most people who experience issues using an adapter in conjunction with their Model M are generally using one of those cheap alternatives. Rarely have I seen a post from someone who had an issue with a Bluecube.

As far as I know, we're here not to lambast

You mean lambaste? Anyway, lambaste means to attack verbally. No one's attacking you, though someone who's overly sensitive about anyone challenging their assertions might think so, I suppose.

If you want to spend more on converters, that's great, knock yourself out. It certainly doesn't cost much to try one of these inexpensive ones, though.

Like I said, the Bluecube has a track record of just working. The cheaper alternatives don't. If someone wants to spend a few bucks and the time waiting to try out the cheaper alternatives, more power to them. I'd rather be safe than sorry, but that's me. I mean, we're talking about a difference of $7. Whoop-de-doo.

And frankly, a $2–3 part doesn't seem worth all this controversy and fuss. But of course the Drumpf Age is upon us... It may now be stylish to become belligerent over even the smallest matters.  :?D

Blue Cube + 10cm USB extension cable?

[EDIT: It seems that the safest route is to buy a "Blue Cube" plus a short USB cable.]
Those listed cable-based converters have a PCB with chip inside, are therefore active adapters (also called 'converters') and should work just fine on some systems. It is also the same product which the famous big German company "LogiLink (http://www.logilink.eu/Products_LogiLink/Cable_Adapters/USB_20_Adapter/Adapter_USB_to_2x_PS-2_AU0004A.htm)" decided to adopt in their catalog. They cost 0.79US$ shipped if ordered from Aliexpress or 1.00EUR on ebay. Some buyers in the AX Feedback section actually refer to the Model M and report that these inexpensive active adapters do work on their PC system; so before pulling the trigger on AX, the buyer should check the Feedback section of the AX item. It is no guarantee, though, that the AX item will work on your PC system, too! In any case the build quality is cheap/poor, since the cables are not really fixed/glued into place, and if you need the PS/2 KEYBOARD cable connector only, the unused PS/2 MOUSE cable connector will be dangling around with its weight and bulk:
(https://abload.de/img/utb8hs1xdnjxkjksaiyq6zbuyb.jpg)
(https://abload.de/img/utb8ca12xnixkjksaluq6r4u0o.jpg)

The Blue Cube (https://geekhack.org/index.php?topic=9892.0) is also a generic active adapter designed engineered manufactured in the chinas and a much less common item on ebay, Aliexpress, etc nowadays. In Europe the only distributor is Compustar and they sell it for GBP4.75 (https://www.computerstar.co.uk/usb2actvps2-usb-a-male-to-ps2-female-ps2-active-keyboard-adapter-uk.html) which is a nice price. Of course, feel free to pay 16.00US$ plus shipping (http://clickykeyboards.com/product/ps2-to-usb-adapter-converter-for-keyboards-short-usb-cable/) to get it from a US source. The PCB looks simple (https://www.youtube.com/watch?v=45LcRUNM3wE).

I ordered an even less common adapter for EUR2.99 instead. The ebay item (https://www.ebay.de/itm/301961610856) title says Fujitsu, aha:
(https://abload.de/img/sl1000vxu38.jpg)
I will be very satisfied if it works well and on all of my systems (Win7, WinXP, raspi) and if the build quality is decent. I could place the item flat on the floor or on the PC case. I have no doubt that the item has a PCB and chipset inside too, thus being an active adapter. For sure it is the bulkiest PS/2-to-USB adapter on the market but i also expect a nicer make than the Blue Cube or the generic cable ones.

I will test and report, stay tuned.

Btw my 2966 PC is old and does have a PS/2 port, so i don't need an adapter for my ~1999 Model M PS/2, but i am a sucker for accessories or good quality stuff.

Hasu makes a TMK firmware compliant converter for mini-di (ps/2) and other odd connectors. Second best to an xwhatsit, of which you can only add to Fs, M SSKs and Wheelwriters.

https://geekhack.org/index.php?topic=72052.0

I've had an old blue cube that failed after 4 years. The blue cube quite an old boi, many of the newer converters are just better in most ways. This works fine too if the other prices you out.

Many Model M users on GH have reported issues using cheap adapters. Few have had a problem using the Blue Cube.

Cheap adapters rarely work because they don't pass along enough current to the keyboard, nothing since the early 90's has needed that much power. This is also why ps2 ports on motherboards may not be capable of running a Model M as well.

A work around is to use the power wires off an old usb cable to actually power the keyboard as even USB 1.0 has twice the power of most modern ps2 ports, which already can pass more power than many of the cheap adapters.

I've used my blue-cube on several keyboards and never had issues.

I'm also using a very cheap but also relatively new LGA 1151 motherboard and the PS/2 port has worked with every keyboard I've thrown at it including a Model M.

I recently needed to get an adapter in a pinch and got the startech USBPS2PC after reading several reviews on amazon from M owners that had zero issues with this even after having issues with other adapters.  It worked fine not only with my M, but also the M2.  It's not the cheapest, but CDW had it in stock for pickup same day.

today i got the (apparently active) adapter and it works beautifully with my tested systems: raspi, Win7, and WinXP. No need to install drivers, all 3 test systems were able to recognize the adapter plus the PS/2 keyboard automatically On the raspi, i had to reboot the system. The Win systems were plug'n play. Wonderful.

The adapter came shipped as bulkware in a ziplock bag including a multilingual instruction manual booklet(!). The small professional/commercial looking label sticker on the bag says "Fujitsu Siemens Computers (FSC)" as does the invoice, but there is no such labeling or branding on the product itself:
(https://abload.de/img/wxcamera15096236591250hu18.jpg)

That sticker and the product sticker on the bottom refer the number S26391-F5100-V100, which seems to be the official manufacturer's product number. It is unclear whether FSC is the original designer and manufacturer of this product and created this product code or FSC acts only as importer/distributor/trading company for the item which could be designed and mass-manufactured by some noname Chinese or Japanese backyard factory :)) . In any case, googling the number leads to the PDF datasheet (http://www.partsdata.de/datasheet/de_DE/partsdata_USB-0606.pdf) issued by another vendor in gemani who sells it for 5.95€ plus shipping (https://www.partsdata.de/usb-kabel-usb-zubehoer/usb-adapter-konverter/usb-auf-ps2/usb-0606/usb-ps2-adapter-fuer-ps2-tastatur-ps2-maus).

With the help of the USB doctor we are learning that my 1999 model m keeb draws 0.10A in standby, 0.11A when the user does happy hacking, and additional 0.02A for each keeb LED: when NumLk CapsLk ScrollLk are all on, the keeb draws a total of up to 0.17A or 170 milliamps through the USB channel. I don't know if 1984 model m keebs draw the same max amount of current. A modern mechanical keeb, e.g. the A-JAZZ or iKBC line of mkb's, certainly draws more current from the USB channel to power all the RGB lighting effects etc.

(https://abload.de/img/img2017110214434672ui8.jpg)

The build quality is not bad. It is decent, nice, and nothing extraordinary. The plastic material and construction feels sturdy as imagined. The total weight of the product, i.e. adapter plus its fixed attached USB cable, is 56g, with most of this weight originating from the thick high-quality USB cable.

(https://abload.de/img/img20171102144508lgu69.jpg)

Since there was that label sticker already available from the plastic bag, it inspired me to act geeky and cut out 2 stickers. One for the top face of the adapter:

(https://abload.de/img/img201711021503138hutc.jpg)

And one for the bottom side of the adapter:

(https://abload.de/img/img20171102154646pouubz.jpg)

Lol, i don't have thin powerful double-sided 3267 adhesive tape in the household. So i am trying liquid glue instead, probably with a FAIL, i'll check tomorrow. In any case, this buy for 2.99EUR shipped was a WIN, no doubt. The postage on the padded shipping envelope was 2.60EUR (Deutsche Post Maxi Brief (https://www.deutschepost.de/de/b/brief_postkarte.html)), so he earned 39cents yes?  :thumb:

At first, i was thinking about the PS/2-to-USB mod (https://www.youtube.com/watch?v=8thH3EoIGx4) but since my FSC adapter is so nice and I want to keep the PS/2 plug for my other PS/2 PC systems, I am not going to do the mod. My keeb has an original thick PS/2 cable and i would feel silly to cut it off for an unnecessary mod. I prefer to keeb my treasured collection items in original and pristine condition anyway. Also keebs the resale value up. The guy in the video is modding a June 1998 IBM UK Model M; my unit is basically the same, produced half a year later than his. Both glorious fresh Model M makes!!

Thank you for the awesome review on the converter!

I couldn't seem to find it on the US ebay site.  :(

oh thanks for the kindness!

sheeet .. looks like that vendor sells it for EUR1.99 only (https://www.amazon.de/dp/B001KTTWN6/) on amazon gemani incl. FREE national shipping, my bad. A 2-pack set costs EUR3.98 (https://www.amazon.de/dp/B01LX5Y1XB/) shipped, which makes sense. On ebayDOTde that same vendor doesn't ship to many countries, he excluded most destination countries.

i mean, even if the FSC adapter is a serious or superior build (which i think it is btw), it wouldn't make much sense to get it shipped from gemani (shipping cost 3.70EUR (https://www.deutschepost.de/de/b/briefe-ins-ausland.html) min.), simply because guaranteed working active adapters, such as the Blue Cube, are available on Ebay International with unrestricted shipping destinations.

How many pcs would you want and what's your destination country? If you really/urgently want this particular item for some good reason  ^-^, maybe i could order it with your money :-X and then receive'n forward the package to your given address. i wouldn't mind helping out a fellow keeb geek  :))

Have you tried the 0.79US$ AX adapter (https://www.aliexpress.com/item/Marsnaska-Hot-Sale-1PC-USB-Male-To-PS-2-PS2-Female-Converter-Cable-Cord-Converter-Adapter/32836698886.html)? Looks like an active adapter but may still be inferior to the FSC adapter. If total cost matters, i'd try the AX adapter first, before looking for other offers. If i lived in the great britain, i would have bought the Blue Cube and not the FSC adapter.

From what I have seen, the Y adapters work great on keyboards with a very limited rollover. However, they will absolutely bug out if the keyboard can successfully register too many keystrokes. The y adapters should work fine on model M's since they don't have a ton of rollover in the first place.

I don't need it for sure as I have 3 converters of 3 different types now that do work.  But as you know with keyboards--always nice to have one more. :D

It would be interesting to see if there's enough interest here to do a group buy because that would be pretty cheap to get and then send via dhl to the US for distribution here or direct from there via post.

I don't have much faith in the 'direct-from-china' goods as they are trying to eek out as much profit as possible and know they don't have to support the product, which is the opposite of a quality product that a company will stand behind 100%.  Sometimes it can be worth it, but other times it's just a failure waiting to happen when you need it to work.

I guess my offer to help stands. A 500g letter to the US would cost 3.70eur postage afaik, 1 FSC adapter costs 1.3eur\pc if I order a pack of 5pcs at once. Registered Letter (tracking number) would be additional 2eur. DHL would be too expensive, like 16eur (https://www.dhl.de/en/paket/pakete-versenden/weltweit-versenden.html) for 2000g parcel. Fujitsu is a Japanese company but FujitsuSiemensComputers has its main activities in gemani. I could call them and ask which factory (where) that adapter was manufactured in.
Title: Re: Suitable USB adapters for IBM Model M?
Post by: SamirD on Fri, 03 November 2017, 09:41:24
So that's not too bad as it would be about 5eur per adapter?  Still cheaper than a lot of the options stateside and very competitive.  I'd make a thread in the group buys section and see if you can get 4 more interested--because you have one interested. :D
Title: Re: Suitable USB adapters for IBM Model M?
Post by: leech on Fri, 03 November 2017, 10:58:19
yes 5.0eur/ppl if there are 5ppl wanting 1pc/ppl and if i shipped the 5 envelopes separately to 5 different international destinations.
if there is only 1ppl interested, the total would be 5.7eur i guess, with no tracking number.

group buy section? nah it's okay if ppl post their definite interest just here and bump the thread. Sending out 5 envelopes or more would only mean more work for me. haha not looking forward  ;D

That's not too bad for just one person as that's under $7usd.  If you're willing to do that for me I'm in.  It will be cool to have a real German-Japanese converter. :D

Hello everyone,

I just got this:
https://www.aliexpress.com/item/Ugreen-USB-Male-to-PS2-Female-Cable-Adapter-Converter-Extension-Cable-Adapter-with-chipset-for-Keyboard/32804535498.html
adapter/converter from some Chinese company called Ugreen in the mail and it seems to work perfectly with my model M on Windows 10.
Somehow they can ship it to almost anywhere for free from china for less than $5 (though the shipping is not very fast, took about 2 weeks).
It is also available from ebay:
https://www.ebay.com/itm/Ugreen-USB-2-0-A-Male-To-PS2-Female-Adapter-PC-Keyboard-And-Mouse-Scanning-Gun-/162520645998
but it's a bit more expensive there.
I've tested key rollover and it's just as mediocre as when using PS2, as expected. It is hotswappable so that's convenient and the build quality is pretty solid.
The only downside for me is that there is also a cable to plug a mouse into that i don't use and dangles loose but that's not a big problem.

That's not how rollover works.  Using PS/2, the Model M can register 16 keystrokes at once if you hit the right combination, and theoretically should be able to hit 22 at once depending on the controller.  Most USB converters or onboard controllers start throwing keys out long before then.

Many buyers in the AX Feedback section actually refer to the Model M and report that these inexpensive active adapters do work.

Many Model M users on GH have reported issues using cheap adapters. Few have had a problem using the Blue Cube.

Again, though, are you referring to adapters or converters? I'd never recommend an adapter, which just changes the connector's shape, for something like a Model M.

Otherwise, I'm sure there are "cheap" (poorly made) converters out there, along with any kind of hardware. But are you specifically referring to the kb/mouse cable type I've described? If so, I'm baffled... I've used dozens of them through the years, obtained from different sources, and recommended them to numerous friends, and they've all worked flawlessly. (The converters, I mean; most of the friends have worked too.) I'm just wondering if we're talking about the same thing here.

I mentioned I was a tech writer just to assure you I understood the difference in terms. You chose to take that rather negatively, but I didn't intend to lord it over anyone. I'm sorry if I gave you that impression.

You may also be glad to know I'm married, so someone's already doing a very good job reminding me how inept and annoying I am when I try to be helpful. :?)

Hi everyone. I'd like to start by thanking all the members of the forums and contributors to the geekhack community, thanks to You I learnt A LOT visiting the forums over the years.

Now that I have a chance to give back to the community, I'd like to report that as I learned a blog post (https://reinout.vanrees.org/weblog/2009/03/10/model-m-ps2-usb-adapter.html) and checked for myself - this particular adapter seems to work fine with Model M. Previously I tested a really cheap one labelled "Monoprice" and it didn't push through any keystrokes.

https://www.amazon.com/Digitus-USB-PS-Adapter-70118/dp/B000M0461M

Not sure about key rollover and other parameters, if anyone wants to suggest some "stress tests" then we can try them.

It cost around 6€, and seems like there's still plenty of them around the world. Hope this helps anyone who's not fond of the blue cube.

Dear reader of my posts in this thread,
in the meantime i got several PM's by (mostly newly registered) forum members asking if i still offer help/service with acquiring that Fujitsu USB adapter. All i can say is thanks for your interest, but getting me involved doesn't make sense anymore. Minimum postage has increased to 8.89EUR (for destinations in the EU) or 15.89EUR (for non-EU destinations) see postage calculator www.dhl.de (https://www.dhl.de/de/privatkunden.html) since 2019-01-01, and tracking (=insurance) costs additional 4EUR. While national letters can contain product samples, sending a product sample in an "international letter" is not possible anymore since 2019-01-01. Only paper documents are allowed as contents in international letters since this year.
I can see that the marketplace seller (on ebay.de and amazon.de) still ships internationally to benelux austria but he then charges 7.49EUR for the shipping cost, which means that he is facing the same problem, i.e. high shipping costs for the buyer. (I didn't test this, but it would be silly to just send off the product in an "international letter" anyway; worst case scenario would be shipper and consignee waiting anxiously for months for the delivery, wasting time and mental energy in the process, and the letter gets lost/destroyed in the postal system without us ever knowing :eek: . Who wants that nerve killing? No thanks, i'll pass.)

Shipping products internationally from ORIGIN:gemani has become prohibitively expensive. It has become a no-go, unless you are willing to pay the 19.89EUR shipping for say Non-EU New Zealand (2kg insured+tracking) or the 11.39EUR shipping for say EU Poland (2kg insured+tracking).

My offer/service was good while it lasted. RIP.  :))

(…)

Btw i still use this Fujitsu USB adapter all the time. It is holding up well, no problems whatsoever. I appreciate that its USB plug does not put any (mechanical/physical/weight/momentum) strain on my PC's USB socket, because i placed the adapter itself on top of my PC's case:
(https://abload.de/img/img_20190213_035024r3jnw.jpg)
I also like using the front USB port of my PC as shown, so that i can easily unplug the USB plug, put the IBM Model M (still attached to the adapter!) temporarily aside, clean my desktop without having the keeb in the way, and vacuum the keeb keys. I do this unplugging/cleaning/vacuuming procedure about 2x per week; and it would be a hassle, if i had plugged the keeb to the back USB port of my computer simply because the computer sits right in the corner of the room, with the back ports being hard to access :rolleyes:
I also place other stuff on top of the PC case: recharging my mobile phone, the house phone, a bad-ass flashlight, a luxury 13400 powerbank (https://www.youtube.com/watch?v=I92RyTfRbT0).
