Unfortunately, this is a MicroVax - not a VAXStation...

The rear panel, from left to right (as you look at it from the rear):

3x DEC terminal connections
1x Sub-D 25-pin (printer, I assume)
Reset button
Mystery DIP switch
A set of diagnostic lights, awkwardly & partially exposed behind some 
case cutouts...
An AUI port
Selector switch
Coax ethernet
Power & power switch

On the upper level, above the Ethernet ports, there's a Centronix-style 
SCSI D-plug, with nothing connected to it. In fact, I've not seen any 
terminators anywhere.

Annoyingly, I don't think I have a DEC MMJ cable anywhere, and it would 
appear that the DB25 port can't be made to be the console on a MicroVax 
3100. So, now I've had to order a cable.... which should be here 
tomorrow, with luck.
