I picked up a pile of cards yesterday at a scrap place. One of them has a Motorola XC81100RC25G and four XC88200RC25E ICs on it. I know the 88100 is a 32 bit RISC CPU and the others are 16k Cache/MMUs. The only other IC on the board appears to be a 24 pin PAL but it has a label on it so I can't read the part number. The baord itself has three high density connectors on the bottom and is marked "Motorola Inc (c) 1989" and measures ~4 1/2" x 8 1/2" and has 6 mounting holes around three sides. Anybody know what it might be for? Joe
