There were several manufacturers of cards shaped more or less like the
S-100. One of the more common ones was the MOTOROLA EXORCISOR series, which
were MOT's development system for their 8-bit devices. The way to start
figuring out what you've got is to count the contact positions at the edge
connector and determine the pin spacing. The S-100 used 100 contacts at
0.125" spacing. It also had on-board voltage regulator(s).
