Hi, I have a largish box of random 72-pin memory, but I can't seem to find a guide online that will help me differentiate the types of memory based on the manufacturer's chip numbers. I recall back in the day, one could look at the last couple of digits of the memory chip part number to tell FPM from EDO, etc. Unfortunately, two evenings of googlings has only found me consumer-level guides to help clueless PC owners tell SIMMs from DIMMs - nothing at the chip level. Thanks for any pointers, -ethan
