[net.micro.mac] 512K HARDWARE REFERENCES ?

WBC@psuvm.BITNET (06/17/85)

       I would like to enquire about sources(periodicals or other) in reference
 to do-it-yourself memory enhancement  of the 1983 Macintosh motherboard. Where
 do I add the data selector chip, resistors, and capacitors that appear on the
 1983-1984 motherboard???
