   I just bought a 25MHz 68030, claimed to be new, with a
ten day money back return guarantee.  After getting home,
I noticed that the part number is XC68030RC25A, not "MC",
which, I would guess, makes it a pre-production chip.  The 
lot number on the chip is 3B56P8815.

   I am tempted to return the part because it was represented
to me as a "68030", which I suppose it is, in some sense.  On
the other hand, I have no idea what kinds minor functional 
problems this chip may have, if I am correct in interpreting
the "XC" designation as meaning pre-release.

   Can someone give me insight into the significance of the
"XC" designation?  What is the likelihood that this chip is
precisely functionally equivalent to an MC68030RC25A?  I'm
not too concerned because if this chip is flawed, I'll just
go back to the store and get a refund.

   Is there someone around the Bay Area who has a capability
to help me test this chip within the next week or so?

   Thanks.
