Howdy. First time, long time. I've really only browsed the Wiki before and drooled over some of the pics in the forum. I already feel welcome: the banner pic was of an IBM Model M 122 key, which I have, and the answer to the account creation question was "Alps," which is what I'm asking about.

So, the keyboard is an NTC clone of their KB-6251EA model labeled "Zeos." AT, 5-pin DIN connector. The key stems are a light grey color, not an off white (see IMG_0924.jpg). They also have raised letters and numbers on top of the switch "casing." They're random numbers and letters and are on either the "number keys" side of the casing or on the "space bar" (north and south?) side, but never on the left or right sides. EXTREMELY clicky and heavy. Nice steel plate mount.

BTW, about half of the keycap stems were broken off inside the switch. That's why the inside of one of the switches in pic IMG_0923.jpg looks odd.

I know these are probably not Alps-made keys, but I'd still like to know where they came from.

Thanks, everyone!
Looks like Alps type T5 but it can be something else/close to that wiki/Alps.tw_Type_T5

Oooh. I think that's close enough! Thanks very much for taking a look.

T5's are pretty cool switches, especially for Alps clones. I swapped them into my macropad where the extra tactility is very welcome :D .

And the gentleman that made me want to find an Alps keyboard shows up. I love your vids, Chyros. Please keep that up!

I'm looking into the keycaps to see if I can pin down an approximate age for the keyboard. So far, possibly early 1990s, but that controller chip 1980 copyright makes me question that.

I'll try to remember to update the NTC wiki page with my keyboard when I've got a chance.

Any idea what this switch is? It looks familiar, but difficult to really tell

Futaba linear maybe?

EDIT: they look similar, but the futaba sliders are rectangular whilst the sliders in the picture are circular.

Hi,
I've just got this keyboard. It is a Unisys model PCK104-SKB, but I don't really know what kind of switches are these. Dome with slider maybe? Sorry about bothering anyone if the answer its too obvious.
Regards!

https://www.ebay.com/itm/S5M-Keyboard-W ... 4185220004. Described as "S5M Keyboard Wiring Plane." It's missing one switch, so you can see the roughly square mount. I think I've seen that mount in one of Chyros' videos.

If it's something uber-interesting-rare, I call dibs. Thanks!

It's the same board (as in, "same serial number") as in viewtopic.php?p=466267#p466267. The majority opinion was "clone," but we couldn't pin down which one.

If it's back up for sale on ebay already, there might be some problems with it.

Linear switches in a keyboard that was found lying outside a textile factory. The keyboard appears to have been part of a computerised weaving machine, and I can't find anything about the switches that it uses. Has anyone seen them before? They've got a pretty short travel, are fairly smooth, and the keycap also serves as the top housing.

Guess it's from some kinda Siemens or related medical device taking the keycaps&switches into account, but no idea what it specifically is.

Copam dome and slider, stiff and mushy, not great. I have some in a Copam K-455. The caps are MX compatible, but the sliders seem to be slightly larger than normal MX, so the caps fit a little loosly on MX switches (but they stay on fine when typing), and normal MX caps won't fit properly on the Copam. Boards are very well built and heavy for rubber domes though.

Thanks for the input! I will try to get it and see if I can you use on my board :D

In the switch's resting state the diameter of the spring is too small to touch the contacts on the PCB. When you press the switch it forces the spring to widen, making the diameter large enough to bridge the contacts, the force of the springs trying to return to its original size, in combination with the conical slider, provides return force and resets the slider.

That are very tactile and very loud, louder than a lot of clicky switches even though they aren't clicky themselves. I think I've found another adding machine with them in it so I might snag that and make a thread about the both of them.

Please do, they sound most intriguing! :D
