Bear in mind that I never used the thing; all I have are old
memories of a magazine ad. My impression was that it was just
like the ISA Osprey.
most S100 system only had one cpu! It wasn't till way
later under IEE696
that multiple bus master slave CPUs were existent and even then less than
common. the typical multiple CPU system would be like a Compupro
8/16 where the one CPU board carried a 8085 and 8088 with provisions to
switch between them.
So the system using the Marinechip T11 board that was the sole cpu.
I have both 8/16 and a true multimaster S100 system the later was
my own design boards.
