Datanetics DC-50 switches, maybe? Look at the Datanetics entry in the wiki.

So I am working with a seller who has a bunch of vintage gear including keyboards. I have not seen one like this before. It is a Texas Instruments keyboard. Sorry about the potato pictures. Does anyone else know more about this and what kind of switches it has?

The profile doesn't seem to match up though. The seller says they look red, the photo it looks brown.

I was obviously joking, I'm sure they are not Alps, I was poking at the fact that they are exactly like Alps but square rather than rectangular.

Your call but I`d keep that offer "low ball" unless the seller has more & better pictures.

That is very true. One could argue that strange keyboard looks like something out of a "bad dream". ;) :lol: Too bad we dont know and it may actually be quite interesting.

What is your take on that switch then Daniel?

Looks like it might be some sort of slider over dome type switch.

Right. While we are at it have a look at the keyboard for the Texas Instruments Professional Computer, not the same but similair:

It's a very strange switch, especially the shapes in the plate/case to either side of it.

Obviously I'm in favour of any course of action (space and funds permitting!) that results in more knowledge.

No doubt. To make things even more fun here`s this which suposedly is the TI Explorer II Lisp machine keyboard posted on flickr here:

Those peculiar bars on the F an J keycaps remind me of something, I've seen them before. Which switches does this thing have?

Funnily enough, I saw them in earlier today, and it's tactile brown Alps:

Could be. Could also be the number two.

The only Decision Data keyboard on the wiki is [wiki]Decision Data 8010[/wiki] and it doesn't have those "bars". The name Decision Data rings a bell, and not because of the keyboard on the wiki (that I don't recall seeing before).

Gentleman.... it has been found...

Long ago, the object that should not have been forgotten was lost. History became legend. Legend became myth. And for two and a half thousand years, the coffee square alps passed out of all knowledge...

Until, when chance came, the square coffee alps ensared a new bearer. The ring-I-mean-coffee square alps came to the texas instruments board...

You know better than most here Daniel that there are many keyboards we do not have present in our wiki:

Its a rubber dome. A pretty strange one. I never looked at it in detail though.

Does anyone know what kind of switch this might be? I initially thought Fujitsu Peerless, but I now doubt that because the design looks quite different. There doesn't appear to be a rubber dome, and instead there is a plastic lever that seems to depress into the bottom side of the key switch housing. The housing is also clipped into the board on the left and right, but when I unclip it there seems to be something at the bottom of the switch holding it in place, and I don't want to apply any more pressure to pull it out because I'm afraid of breaking it.

To add even further confusion, I've got another outwardly similar looking Victor branded keyboard that uses a third type of switch. That one has switch housings that clip in at the top and bottom of the switch and can be unclipped to reveal that it's a Fujitsu leaf spring design.

Photos of the keyboard:

That keyboard in your last picture is a Victor branded Fujitsu FKB4700 for sure.

How do you know that? Hmm...take it apart completely then please. Just saying its an unknown Fujitsu leaf spring design is no good! :|

My 1993 FKB4700 (the one shown on the wiki — one day I'll upload the rest of the photos of it) contains an indication of three models that share that case: 1000, 4700 and 2931.

Top case, with options of 1000, 4700, 2931 and X:

I assume this mystery keyboard is one of those other models. That spring-over-prong design is "always" used with membranes, but it seems that someone's found a way to make it work with a PCB.
