There are in fact several bus systems out there that use the 100-pin
edge connectors.

But... not all of them use the same size board, or have the connector
centered in the same place.

Tracing out the beefy power traces will tell you pretty quickly whether
this is S-100 like or not.

Another identifier: count ground lines. If there are enough, it's
not S-100 :-).

Of course, the critics among us will insist that there was not one
S-100 bus, but in fact hundreds of S-100 busses, all vaguely similar yet
incompatible with each other until you go in and move jumpers and
cut traces, and even then you're lucky if everything works in the
end !
