Have a friend looking for Multibus parts, told him I'd post here in
the hopes that someone here might be able to help it out.  Here's his
request:
"I need an extender board for a system that uses a multibus backplane.
 (Multibus I, MBI, whatever you want to call it)  I have a system that
I need to work on and obviously need one of these to work on the
boards while they're in the unit.
Here's a link to a pic of one similar to what I need:

If anyone has one available, I'd be happy to hear about it and they
can email me at sexsymbol at execpc.com."
