I'm currently working on a single board computer system, designing

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?

Looking at the schematic for the ECB, I cannot find any description of
the signals BAI, BAO, IEI, and IEO. Can anyone shed some light on the
function of these signals?
