Having built [1] a GT40, I have a fair idea of how they work, and what
the problems can be (yes, I made some mistakes that I had to sort out).
Feel free to discuss it with me and I'll try to remember what goes on
(it'll all come back to me when I look at the prints)

[1] Seriously, I took a PDP11/05 in the 5.25" box, dismantled the
backplane, cut the traces to the top 4 slots, and re-wrapped it to take
the VT11 card set and an SPC slot. The order might not be the same as in
a real GT40, but the thing works.
