Back in 1999 I had some of the same ambitions, this (
http://www.chdickman.com/sbc/ ) was the result. Like many things, I never
followed through with it. I could interface 68k, 6800 and Intel oriented
ICs. I think it has all the signals necessary to add an ISA bus. I did save
some edge connectors for the purpose. I keep wanting to get it back out and
play with it.
A monitor listing and the PLD files are online, but not a schematic. I
wanted to put out a schematic, but I got the idea that a kid in college was
using it for a class project. Actually with PLD files should be enough to
figure out the rest for "someone competent in the field."
