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:
