near as I can tell ~ 72pin DRAM (16mbit x 4 x 10 (20? DS?) = with Parity, I assume) 60ns, nothing indicates they are EDO (man. date on the chips of 3rd week of 1996, which is shortly after EDO was released, but my money is on standard 72pin FP 5v SIMM w/ parity)

Thank you good man! o/ Finally I've realized what is 72 pin FP SIMM :) it's used in 486 motherboards,also in Acorn Risc machines maybe and so on. Thanks!

486s and Pentium (1) systems, EDO also came out around that time (about 20-30% faster than standard Fast Page), supported by later Pentiums, and the very last 486 chipsets (ie: FINALi 486 (1995))

by the time the PII was released in 1997, most boards were supporting 168-pin SDRAM (33/66/100/133), including (many of) the later Socket 7, and Super Socket 7 P1 boards
