The cards are, from one end:
M8192
OK, this is the CPU, a KDJ11-A.
M7195
128 kbyte RAM
M8067
Another 128 kbyte RAM
M8045
Depending on the letters that follow M8045, it's between 8 kbytes
and 64 kbytes of RAM. I'm guessing it's a fully populated 64 kbytes.
M8059
Another 128 kbytes or 256 kbytes of RAM, depending on the letters that
follow the M8059.
I've also found out that it ran Venix in it's
first life. It was connected
to a PDP8/A that I also have but can't do anything with because of it's
state.
I'm unclear about the switches and lights, but I have the run light on, the
DC light on, the fixed disk write protect switch out and it's red light out,
and the fixed disk ready switch out with it's green light on.
There seem to be some (slight) behavioural differences depending on which
serial port I plug the terminal into.
It's also particularly confusing, because you evidently have no serial
line cards nor disk controllers in the backplane. I have no idea
how you even got the ODT prompt out of the machine.
Look at the serial ports on the back of the machine, and the ribbon
cables coming from the inside of the cab kits. Which cards in the
backplane do these connect to?
