First off, admitting I am a n00b and asking sincerely for help. I am very grateful.
TLDR: 2 min video:
https://www.youtube.com/watch?v=AN6v82COLkEHow can I get these beautiful boards to work?
I've "inherited" a "Key Tronic Trak pro" (similar/same as a "Trak 101" or "KB 101" I believe). It has two (what I think are) "Mini DIN" with 4 pins. Assuming again one for the keys and one for the trackball. It also has a serial port.
Aside, in the manual below:https://neurophysics.ucsd.edu/Manuals/Keytronic/Key%20Tronic%20KB101%20User's%20Guide.pdfThere are dip switches. The Trak Pro I have has 4; they don't seem to make any difference when hooked up thru a serial to USB converter.So first q: Best approach for getting this up and running on a modern Mac, say over USB? I am fine with spending $$$. If an ADB converter is the answer let me know.
Second q: I've also inherited a DEC keyboard without a model number (I am fairly sure it's DEC). This seems to have a 6 pin ps/2 connector, but doesn't work well when I connect it to my ps/2 to USB adapter which I use for newer Key Tronic boards, or any regular ps/2 boards. Has anyone seen one of these before and got it working on a modern machine?
