OK, this is great!  Can anyone else post or mail any other results?  It would 
great to compile a list of known compatible accelerators.

So far:

-Elevator386 
-Sota386X
-Orchid PC Turbo286e (not Tiny Turbo)

Bad news:

-Intel Inboard 286/386
-Boards that require the removal of the motherboard (Bridgeboard) CPU or require
 backfilling ram to 256K.  (Is this a correct assumption?)


An intrigueing possibility:  There is a Quadram Quad386XT for $555 on page 515 of
the current Computer Shopper.  I called the number but the order-taker did not
know much about it.  Someone from their "technical staff" was supposed to get 
back to me but never did.  I will try contacting Quadram tommorrow.  With the
current glut of 386 motherboards available, accelerator boards have fallen into
disfavor.  Out of 700 pages I found maybe 3 references to accelerator boards for
sale!  This may be a good sign, though, that manufacturers will soon have to 
liquidate leftover inventory at fire-sale prices.

What I _really_ want is a 68030 accelerator for only $555!  :-) :-)
