We have to clean it up but we've got the pattern for a quad height
prototype board. I can share the outline and edge connectors once it's 100%
verified.
Thanks,
Jonathan

Hello.
I'm looking for a PCB layout file / template of a 2 slot Unibus card,
which I want to use in KiCad.
Can someone help me with this?
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.
