80186 CPU Board
This is one of the few 80186 CPU boards for
the S-100 bus. By this time IMS had matured into a state of the art S-100
board manufacture. IMS and ICM were two separate companies that
had very similar product lines when this board was manufactured in 1985.
See IMS History
. It wasn't until 1988
that IMS purchased ICM. As best as I can tell there was one type of
80186 bus master (with no onboard RAM) and at least two slave CPU's.
These today are fairly rare boards.
The top picture is an IMS A1270 "Master 186 CPU Processor" and is the
companion (lower pictures) an A1510 186 and CPZ-186 "User Processor". These
were TurboDos only boards, the User Processors couldn't boot without the
Master Processor. The Master would load it's OS from disk and then search
for running User boards, when it finds a user board at a specific port, it
will then read in the User board's OS from disk and write it into the User
