[HECnet] Bringing up a MicroVAX 3100-80

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.

Thanks in advance
