AT&T Model M Clone? (KBD 305B)
BellLabs:
Hi. I just went to VCF X (Vintage Computer Fest) and bought this beauty for about 20 bucks.
I thought it was a Model M clone at first, but the few threads here suggest that it's a completely seperate keyboard.
Is it possible I could buy an adapter for the serial port to use it as a PS2 or even USB keyboard?
Thanks.

Yes it is an IBM clone. This board is buckling spring, just like the model M. I believe that you can use a teensy to convert the keyboard to USB. Ask me if you need any specific questions. Using a Teensy to convert is very easy. I am trying to use a pro micro clone(cheaper than Teensy) to convert a wyse board and I am having some difficulty. Could you open the keyboard up and get a look at the back? I am curious as to what AT&T used to hold the board together. I know that IBM used plastic rivets.

This is excellent advice for a different KB than this one.
This is the less-common AT&T KB305 (model M licensed technology form at&t) taht is not PS/2. I believe it's some kind of serial. good luck converting it, i recommend soldering a controller to the membrane connectors.
great find and total steal for $20

It would probably work just fine with the Colossus controller if it is a Model M matrix.

I have the feeling it is!

I have both variants of the keyboard and you can use the PS/2 cable on the variant that comes with the DB9 connector. I think that AT&T just used a different connector for some of their computers.
