I got the board shown below from someone (without any documentation).
I am very sure this is an Exorbus module, both from the name (MEX =
Motorola EXorbus), and from the fact that the board came with manuals
for 2 other Exorbus Boards. The big edge connectors are identical (as
far as I can tell from the picture). Motorola no longer makes these
boards, and I couldn't locate manuals or data sheets in any of their
publications.
The board is labelled:
(c) Copyright 1979 by Motorola Inc
Motorola Microsystems
MEX68KDM
M68000 Design Module
The board is about 15 inches long, and about 10 inches wide. It looks
like this:
-------------------------------------------------------
