Hmmmm I don't remember my original PC having all the chips in sockets 
nor do I recall it having 64Kb DRAMs.  I clearly recall that it had one 
bank of 16Kb DRAMs soldered down and sockets for three more banks of 
16Kb chips.  The only other sockets on the board where for the ROM, CPU, 
and math coprocessor.  hardly a fathful reproduction.
