If you use a 100pin connector with odd or alternate pins as ground then
the backplane can be ribbon cable with IDC connectors!

Are there any 80-100 pin buss structures already
in use I could copy that
might fit my bill? I'd rather do something that might be compatible with
something else out there if it's similar enough to what I want to
accomplish.
Maybe not 80-100, but how about STD bus?

Hmmm, maybe originally, but I've seen STD bus cards for just about any 8-
or 16-bit CPU you could imagine. Didn't Fujitsu put out a 6809-based STD
bus PC? I think they called it the FM-7 or some such.
And STD bus is still in use.
Cheers,

with 'D' - if anyone is interested, I'll dig it out and get the name.
