Lucky Me, somebody turned up some history on my oddity
There is in fact a desktop emulator of a Unisys mainframe
that boots the coprocessor from within OS/2. I have one
here. Happened across it by pure luck. I'm not an expert
in the MCP O/S so have been in lurkmode on this for a
longnow while.
From what I've been able to tell, the thing
executes a superset of the old
1107 instruction set. Given the date of introduction
(1989), it's got to
be one of the last holdouts for non-power-of-2 word length (36 bits). An
odd bird indeed--OS/2 sounds as if it was used to handle I/O for the Micro
A.
