I'm looking to add scm zip memory to the A3000. My supplier only has 80 ns available

What I am looking for is a list of known working part numbers and their mfg.
For my particular instance I only know of 1 part number/mfg that works with out any drama in the 16 mhz version of the a3000 (rev 7.5) oki m514402a-70z scm the replacement Fujitsu MB814400a-70psz fpm does work if you manually turn off the 68030 cache and burst mode problem is your can't boot from floppy w/o editing the start up scripts, and for propriety disk you are just plain out of luck. In a nutshell, a simple cross reference guide with known working zip memory numbers would be appreciated I'll be trying out a 25 mhz mod (clock and socket) and will report back. |
