My "new" Microvax 3100/90 has 4 serial
ports, 3 MMJ's and one DB25-M. The
MMJ's are numbered 0, 1, and 3, and the DB25-M is labeled 2. I assume the
one labeled 0 is the console OPA0 port. There is a big yellow sticker above
the ports that says "0 OPA0" but it has a big arrow pointing to the RIGHT.
(the ports are numbered 0, 1, 3, 2 from left to right). This sticker seems
to be really odd.
OPA0 is port 3, the rightmost MMJ.
My MMJ cable should arrive Tuesday. I'm planning
to connect to my PC serial
port and use a terminal emulator to control the console. I assume I need a
null-modem/crossover cable to go from my PC COM port to the MMJ jack...
Correct me if I'm wrong.
The MMJ cable is a crossover cable itself. You just need an adapter
to match up with the PC's serial port.
Does anyone know if it is possible to use the DB25-M
port as OPA0 instead,
like you can on the VAXstations? My MMJ will be here on Tuesday, but if I
could use the DB25-M, I could get my machine up and running this weekend :)
Not that I know of.
