I would be interested in seeing a list of the variations of the PC (with 
/ without tape interface) and the XT
as well as the AT.  the things I'm interested in is memory config (which 
type chips) number of ISA slots,
and the on board varations such as having or omitting the tape interface 
present on the original PC. (those
sort of variants).

I may have a motherboard in the heap somewhere with 5 slots, and 64K but 
I don't recall seeing an
8 slot (XT) board with only 64 k.  I have seen two variants of memory 
types on both the XT and AT,
as far as the chips.  The AT of course had the silly stacked memory 
chips, initially.
