  I have a Megatek X-elerator (sp?), new-in-box, that I've had for
easily 30 years.  If memory serves, it's a 6U VME board.  I've never
tried to do anything with it.  I will dig it up and see if there's
anything else in the box.  Ping me (you know all about that ;)) and
it'll bubble up to the top of the priority list.

  Now that we are building workstation exhibits at LSSM/MACT, this sort
of thing is becoming more relevant to our work here, so prioritizing it
won't be that hard.
