Smile. It's a decent machine.

Both are memory boards. Don't know for sure how much. 8 or 16 megs apiece,

Sounds like a graphic subsystem.

Controller for the TK70 tape drive.

Controller for the RA70 disk. (The controller can have up to four disks

CPU and memory minimum.
I'd recommend to remove the VCB02 and CXY08, since you don't have the
peripherials. Move all other cards up to delete the empty space in the

Turn on the power.

It's a pretty easy machine to play around with.

Plain terminal will do. In fact, it *expexts* to get a plain terminal.
The MMJ is a DEC thingie. The electrical levels are compatible with
RS-232. You can get a cable from DEC, or perhaps some other place. I also
know that the pinouts have been published on the net from tim to time.

Protocols? That's software!
As for electrically connecting it, that depends on what card you put in
the machine! Paralell or serial, you choose!

I assume you have 10Base2, so get an AUI-cable to extend the connection
from the DELQA to outside the box, get a 10Base2-transciever, and you're
set. For other types of carriers, get the proper transciever! :-)

Yes. Boot NetBSD on it. Get 1.3.2, which works pretty fine on the machine.
You can netboot it to get started.
