Hello there,
I'm new to the classic Mac world and bought me an SE FDHD recently. Unfortunately this was battery bombed and probably beyond repair. I got me a replacement motherboard which once was an original Apple repair part. The board does look ununsed. I installed 4 identical 1MB SIMM modules and removed the RAM config jumper. Upon powering on I got an sad Mac and an error code 00000005 00820082. I tried different sets of RAM modules and I got different sad Mac codes. The second line of the code probably changes on every power up. If I set the RAM config jumper to the 2/4MB position I can power up the Mac and boot it to System 6. The Finder reports 2 MB and the Mac is useable. I don´t know if the board then uses only one of the two banks or only half the capacity of each module.
I tried RAM modules from Samsung, Siemens and NEC, with or without Parity. 70ns or 80ns. It does not seem to make any difference. On every change of the modules I fear breaking the retaining clips of those slots. :-O I cleaned the contacts of both the modules and the slots and used contact cleaner.
Am I missing something? Please help a classic Mac novice to get the little machine up and running.
