How's about a Glitchbus board set that's compatible? I was planning on doing it

That would be very cool. Something along those lines was my plan B and
I even dug out a tube of 6802's for the effort. I think I could wire
up a prototype over a weekend. MC6802 is a nice "cheat" as you don't
have to mess with the two-phase clock stuff.
What would be really slick is an SBC that has everything on it to be
either an Altair 680 or an SWTPC 6800 just by changing some jumpers,
switches, etc. and putting the correct ROM monitor on the board.
Something around these lines ?

Yes, it runs, I still have some PCB's left.
Works with both 6800 or 6802, memory map is defined with a GAL.
