Can I run both the 3.5" See reader questions & answers on this topic! - Help others by sharing your knowledge The following is a cross-reference list of 256 by 1-bit dynamic memory chips that are usable for 3b1/7300 memory upgrades: AM90C256-xx AMD Advanced Micro Devices MB81256-xx FUJ Fujitsu HM50256-xx HIT Hitatchi HY53C256-xx - Hyundai P21256-xx - Intel M5M4256P-xx MIT Mitsubishi MCM6256-xx MOT Motorola UPD41256-xx NEC NEC Technologies MSM41256-xx OKI Okidata KM41256-xx - Samsung TMS4256-xx TI Texas Instruments TMM4256C-xx TOSH Toshiba The digits in xx are speed designations--common values are: xx=10 for 100ns; xx=12 for 120ns and xx=15 for 150ns. Since it is now economically advantageous to obtain chips from third parties (private sales, auctions or hamfests), the manufacture's LOGO and identification stamped on the chip may be the only clues one has for a scavenger hunt. If the experimentalist is not familiar with the Manufacture's LOGOs, a perusal of a computer magazine (PC World, etc.) should help one to become familiar with most of them. Good hunting!
