Dorkvader, what do you use to fix the cracks ? The plastic is the same is in the F 122, and fogat.digs tried glue them back, but my understanding is that it didn't bound well.
Also, are yours usable now ? Mine works with the same Soarer converter I use for F 122. I saw in those pictures that some unsavers come with different plugs, not the old DIN 6.
Mine is from 1988 and has new format caps for CTRL and ALT. Yours must be older.
If you can get more, I'm interested too. Thank you.
Mine are the unsaver for CAD work. Yours should work on a normal PS/2 / AT to usb converter, though I do recommend the soarer adapter. Mine do not currently work on USB, but both the cases on mine have no damage or cracks that I can see, just some dirt.
If you look through the pictures, you'll see two outputs: one is a massive connector, that probably shares some similarities to a 3291 "model C" keyboard protocol; the other I have no idea about (maybe it's an input!)
I have some better pictures, taken outside, that I should upload sometime.
They are from 1984, but the IBM 5083 / 5085 CAD workstation they went with has been out since 1983 at least. It makes one wonder if the 122-key keyboard evolved from the "Unsaver".
