  Is this thing L-Shaped?  If it is, then this is the
'l-board'
 that goes into Hp 9000/375 (I have one of these sitting in my
 garage). 
Yes, it is.  About 7 1/2" by 8", with a 5" x 4" chunk cut out.

...
  Anyways, many of these were swapped out in favor of a
*real*
 68040 running at 25 or 33 Mc.  HP used these boards because
 (presumably) they had their 68040 system board laid out and
 ready to go but Moto didn't quite have the silicon yet.

 SO they outfitted the 9000/375 with this kludge (that used a
 68030), and the later 380's were the same hardware with the
 real processor installed, instead of the L-board. 
That sounds plausible.  Thanks for the info.

...
  I would be really curious to know if this thing
functions
 as an '040 in other systems . . . 
Well, if I get the chance, I'll try it.  I wouldn't be too hopeful, though;
partly because it's quite large, and partly because it's been lying around
without any antistatic protection for months, and has been handled by
several people in that time.
