Megs.

 Most of the 72 pin simms seem to be EDO Ram chips. Will there be a
problem using EDO ram in this computer? Also if I buy more memory do I
need to buy only EDO ram or can I mix them?

Should I expect any speed improvement with the EDO Ram?"

Captain Zyla:

Your manual is correct but is must be FPM Fast Page Mode memory, not
EDO.  Some early Pentiums have a problem with EDO. And Pentiums, as you
are aware, requires matched pairs be installed, while 486s (with 72-pin
slots) do not.
