-I was digging around inside my xt-clone tonight and was trying to find the
-locations of the various chips.  I Know that the microprocessor is the 8088-2
-but there was a chip next to it with the following on it:
-            NEC 8643w5 V20
-            D70108c-8
-            '84 NEC
Actually, the NEC V20 is their souped up version of the 8088.  If it is in a
socket next to an 8088, someone put it in the wrong place.  It should replace
the 8088.  As you guessed, the socket is for an 8087.  Placing the V20 in 
the 8087 socket may have zapped it.
