address and data lines running through it and enough control lines...
In the case of my MITS setup, the signals were pretty simple--8 I/O address
lines, 16 data lines (IN/OUT) and decoded IORead and IOWrite. +5 and +/-12
power lines and the rest were grounded. There wasn't a ground for every
signal, but given the speeds it worked at, it was fine.
