Good, then I was probably looking for a chip that was never there.
great, I will probably ask for more clarification on this later on..
Ok. It's been a while since I've had a Qbus card in
my hands and this card really looked like one. Too bad that
it won't accept a diagnostics terminal like the microvaxen.
Unfortunately I did not find the rest of the terminal.
There's a socket for a 5037 video crt controller in the card (which is
also missing). What is the 1/4" plug connector for?

Mine has an empty socket there. Looks from how it is wired that it is meant
to take another m1-6322-9, like the three above it. (Perhaps an option
ROM?) 2) Can one use
this board to run older pdp8 software?
Yes (some). Can one connect a terminal to the printer port

I don't think it wants to talk there (without extensive firmware work). It
wants to plug into the terminal backplane (which I am sure is *not* qbus),
with a keyboard plugged into it. From what I
have read, that could be a challenge. It would probably be
easier to build a
compatible video adapter and keyboard stuff for it. The
floppy is an RX01 with a special cable, IIRC.
