A lot of the multiuser S100 systems used CPU/memory/IO per user
running CP/M and a additional CPU/mem/IO/disks running MPM as
server to provide inter-cpu communication, file services and
spooled printing. Some ran Multiple IO subsystems and one cpu
to time slice task swap.

This is the crush question. Board names/model numbers may help.
Then those specifically familar with Vector can say whats what.
