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
    Now from this I know that the chip was probably made in the 43rd week of
1986 and that NEC is the manufacturere.  But I was wondering is this a Math
Co-Processor??  I have heard of the 8087's but this one is not one that I have
heard of.

Any info on this chip would be a great help.
Thanks
