I've laid out the first version of the SBC, and I realize it would
cost nothing to add an edge connector on the PCB, allowing expansion
options.? As well, assuming the design has any merit, I can see
creating one of these SBcs for each family (8080/Z80, 65XX, 68XX, and
maybe even 16 bit options like TMS9900, 68K, etc.)
You know this projects?

I've followed the N8VEM project for many years, but I had forgotten
about looking at their bus design.? Thanks.
