Mike and I went to one place today and found the remains of a Data General
Aiivion (sp?) in the scrap metal pile. We had gotten there too late to
save it. :-( I did get the CPU module out of it. It has three large ICs on
it. Two are XC88200RC25B s and the other is a MC88100RC25. Can anyone tell
me what exactly these are?

The 88000 was Motorola's late 1980s 32-bit RISC processor, intended as a
general-purpose successor to the 68000 series. Not particularly
successful, and fairly soon dropped in favour of the PowerPC.
The 88100 is the CPU, and the 88200s are MMU & cache (most likely one for
instructions and one for data).

IIRC, the 88100 is the first generation 88K RISC CPU, and the 88200 is
a "CMMU" (cache & MMU). A normal 88K system used two CMMUs, one for
instructions and one for data (i.e., modified Harvard architecture), but
in principle more could be used.

Motorola labeled the first run of parts XC (experimental?), then switched
to MC for production. I worked with one of the first 68020 boards from
Force Computers which had an XC68020 on it.
If you find info on the MC88200, it is the same as the XC88200.
