I have obtained a MicroVAX 3100-80 with a Storageworks
pizza box, a CD-ROM drive, a tape drive, some cables and no monitor.
It powers on, does not smoke or explode. The 8 LEDs at the back settle down to all on
except 2 and 3 counting from zero on the right. I can hear a hard disk spin up.
The cables include two MMJs. I have a PC with a 9-pin female serial connector. It runs
Linux.
The first two of many questions: does the ?0? connector connect to the console? What
exactly do I need to do to connect the PC?s serial port to the MMJ cable? Note: I have
passable soldering skills.
Next question will be about the BNC connector and networking. One thing at a time.

I have a MicroVAX 3100 Model 95.? The backside is nearly identical to yours.? The
OPA0: port is #3 (don't ask me why)
