I tried swapping it for a couple of chips I picked up a Tanner's but
neither one worked (or at least I couldn't get the board to boot up
with them in it).  I don't exactly what they were.  I was looking for
an 8032 and Jim Tanner showed me some tubes of new chips someone had
sent him that were supposed to be compatible with 8031/8032 CPU's.
He gave me a couple to try for free since he didn't have any docs on
them.  I should have noted what the manufacturer and model number was
but since they didn't work, I just dropped them back off at Tanner's
the next time I was there...  In any case, they didn't do any damage
to the board and it worked fine when the original chip went back in.

I used a specialized PLCC extraction tool called a "paper clip" to 
remove the chips.  :-)
