Saw this the other day but I don't have a use for it. awesome metal case, industrial strength plug.

err what kind of switches would these have?
-
Good question! buy it and find out.
-
>_>
-
Look like cherry style, and 2-shot probably
-
I just bid on this sucker. Could work out well if it is indeed a 2 shot cherry (looks like something along the lines of an 1800

I don't know about that, if I was going to guess anything I would say alps but the key caps look funny so who knows.
-
It might indeed be ALPS, as the legends look red on the left modifier keys, much like my northgate.
-
yeah when i saw it, my first thought was alps..
-
Only Few alps keyboards use that kinds of enter key
-
Very similar to that German military trackball keyboard. My money is on Marquardt switches.

I can think of more than a few =P But yes, I guess a majority of US layout Alps keyboards used the inverted-L enter.

16 minutes to go and still the highest bidder... I don't trust a single one of you ebay sniper motherf#$%ers, but I think it's mine.
-
Well I am glad you got it, I would like to know whats in it. I just don't care enough to buy it. I hope it works out well for you.
-
That is a neat keyboard. Definitely industrial strength.
-
before I won it I emailed the seller asking him to pull a keycap and take a pic, but he was afraid of damaging the board... oh well, i'll find out soon enough :D

Tell him he's a stupid pansy and plucking off a key won't do a damn thing, especially if he's advertising it as "industrial strength". Rather counter-intuitive.
Well hurry up and tell us! I WANT TO KNOW, I CAN'T WAIT.

I demand a cookie if it turns out to have Marquardt switches.

I'll let you know, ch

It does NOT appear to be cherry or ALPS switches. I'll have to look closer at the Marquadt switches to make a call there, but I seem to remember they had a cross shaped stem like cherries... this board appears to have a mechanical stem with a rubber dome slid BETWEEN the key cap and the stem, essentially taking the place of a spring. The action is interesting to say the least. I'll post pics tonight or tomorrow.

Sounds like a rubber sleeve switch. They're used in the IBM M4-1, various laptop keyboards from the early 90s, and the occasional desktop keyboard.
Seems like I won't be getting my cookie after all :P
-
Mitsumi? Sounds like a sexy japanese punk girl :P
-
I've never heard of or seen such a switch design. Oh well, live and learn ;)

NO COOKIE FOR YOU!

-
So this keyboard is a rubber dome with sliders?
-
It appears so, but the slider is below the rubber dome... it's bizarre.
-
That does seem like a strange mechanism for a key. Maybe the rubber dome is used to keep dirt out of the key mechanism.
-
That might have been a design consideration, but the rubber dome also acts as a spring to make the key cap bounce back after actuation.
-
It's not a rubber dome with slider. The rubber sleeve provides the tactility and the hysteresis, and the shaft on the underside of the keycap sticks through a hole and actuates the membrane directly
See pictures of a dismantled M4-1 here. (http://geekhack.org/showthread.php?t=3925&page=10&do=comments&highlight=Unicomp)
-
The feel isn't that bad really... I just wish the space bar were a bit stiffer. It *is* hard to imagine this being used in an industrial setting, however.
-
I would be careful about this one.. the keycaps look 100% identical to a terminal age HP keyboard I own. Same red legends, same weird curve on the keycaps. The HP board is a rubberdome. But who knows, maybe you get lucky with this one.
-
Well, different keyboards are for different people.
-
this board appears to have a mechanical stem with a rubber dome slid BETWEEN the key cap and the stem, essentially taking the place of a spring.
Sounds like a foam and foil keyboard, like the KeyTronic. A rubber cylinder in-between the keycap and slider. The keycap snaps to the slider.
-
sixty, have you read the thread at all? I've had the board for 2 days, and it appears to be a mechanical switch with a rubber dome for "hysteresis" as ch put it. It is definitely an AT board, and works fine with an AT-PS/2 adapter.
-
Well. It's basically a rubber dome switch, except the keycap actuates the contacts instead of the dome. I wouldn't call it mechanical.
Yeah, this is what that Mitsumi used. Nasty nasty thing, hated typing on that.
Approximate feel of a BTC foil and foam keyboard. Not sure if the Mitsumi has a membrane though.
The M4-1 feels like a stiff scissor switch keyboard. I'd imagine that the rubber sleeve would work better for shorter travel than longer ones.
-
Well, I suppose we could get into a debate on the meaning of the word "mechanical". It could be argued that rubber dome boards are mechanical as well, and the touch screen or roll up membrane boards are the only non-mechanical boards. I really don't want to have that debate, but if backed into a corner I could make a case.
Anyway, without taking apart the board and seeing the way the "switch" makes contact with leads or a membrane, I can't really argue by the definition for "mechanical" most widely accepted here. I also have no plans to disassemble this board to check any time soon.

Hah, No I have not. I was stuck on page 1 and assumed the thread ended there. I guess I lack sleep. Apologies.
