Yeah, I had thought of that, as the only S100 boards I have seen were
shorter, but then again, I don't have any S100 hardware, so I don't
know if there were different sizes. I downloaded the S100 bus
specification, and this board seems to match up as far as the power
connections are concerned, pin 1 (+8v according to spec) is connected
to the power inputs of the 7805's, and pin 2 (+16v according to spec)
is connected to the power input of the 7812. Pin 50 is definitely
connected to ground, as is pin 100. I'm not going to blindly attempt to
apply power unless I know for sure that I can hook it up properly. It
definitely appears to be the S100 bus. Were there any tall S100 boards?
What about a bus that uses the same connector and similar power
connections?

Thanks!
