Re: I could use a hand locating hardware bits and pieces and/or technical documentation for repair.

Based on some more work, I've decided the following:

I may have not had my power wired in properly and the data I've had so far may have been noise.  I'll give this another shot in a bit and maybe get more interesting data.

Now that the machine is running, I can tell you that the port does generate 5v where I expect it to, so that's at least something.

The Burroughs/Unisys keyboard, once open, starts looking a _whole_ lot like the AT&T one.  Based on continuity tests at the plugs (which are also 8 pins) I find that three of them are connected together and two of the others are connected together, leaving three other lines.  It would make a whole lot of sense for these to be negative, +5v, and (rx, tx, rst) respectively, exactly as in the other keyboard.  I'm kind of wondering how difficult it would be to just wire it in and try it.  Perhaps not much.


Interestingly, when the bad keyboard is plugged into the machine with a mouse on the other side, the mouse works fine.  This suggests to me that there must be some logic in there that's working properly.  Perhaps whatever runs the keyboard matrix is the only thing that's not functional.
