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?

I'm currently working on a single board
computer system, designing
from scratch partially as an education experience, and also as
something that might be of interest to others.
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?
