Here's a KiCad template for a double-height QBUS card.  I haven't
verified it or cleaned it up but it ought to make a good starting point
and deleting the QBUS bits will be easy.  Eventually I'll need to do a
quad-height Unibus card too.

If you're building your own DEC boards, this is the best dimensional
diagram I've come across; I pulled it out of a uVAX manual.  The one bug
I've found in it is the "1.00±.010" in the corner where the edge fingers
start.  I think it's supposed to be "0.100±.010" but I'd double-check
that against other diagrams or measure a real board.
