Is 100 ns fast enough? Thanks in advance. O.K. Here's a quote from the A2091 section of the A2500 manual: "You can install RAM chips on the A2091 to increase the amount of 16-bit memory available to your Amiga 2500. You can install 512K, 1MB, or 2MB of additional memory. Note: Use only CMOS 256k x 4 DRAMs with an access speed of 120 ns or faster. Slower DRAMs will not work properly. WARNING: Do not use NMOS DRAMs. The use of NMOS DRAMs will damage the A2091 and void your warranty. There are several brands of DRAM chips available for use with the A2091 Hard Disk Controller, including, but not limited, to the following: NEC UPD424256C-10 UPD424256C-12 OKI MSM514256-12RS Texas Instruments 44C256-10N 44C256-12N Toshiba TC514256AP-10 TC514256AP-12 " There you have it. -- --------------------------- Signature Version 1.0 --------------------------- | bear@bu-pub.bu.edu enge05c@buacca.bu.edu | | "There are many perks in being the mother of a living god. | | Nice apartment, car, free parking." | -----------------------------------------------------------------------------
