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?
