  Yes, 5 VDC and plus and minus 12 VDC. The -12 is only used for a comm
port I think. The + 12 is used for the comm port and the printer. You CAN
run it without the plus and minus 12 VDC but you'll lose the comm port and
printer. You MUST have the 5 VDC.

   I don't know. Maybe it uses the keyboard connector or the expansion
connector. You should be able to trace the KB-TTY switch out if nothing
else. BTW some of my boards don't have the switch. The traces are there and
there's a jumper soldered between two of them.

   Mine say "J1 Application" and "J3 Expansion". The keybaord connects to
"J4". "J2" connects to the printer. I don't know where the comm port is.
Have you looked at the stuff on Rich's web site yet. The manuals there
should tell where it is and how to use it.

  BTW Richard, I haven't forgotten about the PROMs. I got my burner out to
use it and found that I misplaced the software when I moved the burner to a
new machine. I spent two days looking for it but haven't found it yet.
