Also I just found this one (couldn't find any information on it) - I'm guessing Microswitches right?

These could be microswitch SC. I've seen those caps on another ITT board that had both microswitch rubber dome and microswitch plate spring, but it's impossible to tell as they both look externally identical.

I would guess it's microswitch ST keyboard in terms of the ITT logo and the caps style.

Edit: yeah, MS SC, my mistake.

I guess I also found another one that also uses Microswitches? It's an old wordprozessor Wordplex 80-3. Unfortunately I'm pretty sure the seller won't take a keycap off...

Caps don't look like Keytronic foam and foil to me. Enter key reminds me of the Fujitsu Sanyo somehow, but the locklights would be in a weird position for an FLS board.

Yeah, most sellers don't do that. Maybe they would be willing to unscrew the case and take a picture of the insides and the PCB for you. I can send him a message too, maybe he will be persuaded by two politely asking, german speaking gentlemen ;)

It looks angled. If TNT is right and is a Fujitsu keyboard, it can be the unobtanium Fujitsu magnetic reed switch. Look at this Enter:

There really are a lot of similarities between the two. I hope TNT and me will be able to convince the seller to take a keycap off :)

If I'm not mistaken the PCB says "Digitran Golden Touch". Our lord and savior Chyros has a video on those. Seems to be the right one.

Those caps are Honeywell mount compatible ;)

Reported to feel like a heavier FLS with a high amount of wobble.

Any idea what switch type this is? I have spare stackpole key module I bought from someone who harvested another TI-99/4A, so I can return this one to operational condition if I hamburgle it's key module.

To answer my own question I think it's some kind of slider over membrane. The keycaps do look beautiful though.

Edit: Mitsumi KSD I think (which is funny because that switch type seems pretty rare... how are their 8+ revisions for a computer that was only around ~3 years)
