Amiga 3000 fastram suddenly disappeared.

Sorry to drag up an old thread, but I’m trying ZIPtest on my 3000D with ramsey 07. ZIPTest reports:

 ”Unrecognized Ramsey version $ff - this program only works on an Amiga 3000”

@cdh   Is it possible to patch it to work with ramsey 07 (Rev $f)?

The issue i have is my 3000 doesnt register the fast ram when I try with ZIPs (DRAM works ok). I have populated Bank 0 but I get no fast ram. I do not know if it's a problem with the sockets (which I suspect) or the ZIP modules themselves, hence why i'd like to use ZIPTest's capabilities to see if the sockets are ok. I'm not sure A4000RAMTest would do much for me given the machine does not detect the ZIP modules at the moment.

Ok, Chris got in touch and ZIPTest can be run using the FORCE flag!

Yes, ziptest did the job perfectly - it showed a problem with U850 and U851 on Bank 0, and with U870 and U871 on Bank 2. I used contact cleaner and crimped the zip modules legs together so they griped the insides of the sockets rather than trying to push out into the pin-damaged sockets.

Banks 0 and 1 now work so I have 8MB. I think 870 and 871 require being replaced, sadly.
