I recently got a Macintosh IIfx. It wasn't battery damaged thankfully, but nevertheless it does not work. I get a startup chime and the raster screen, where the Mouse-cursor should appear, and eventually the blinking floppy disk, but nothing ever appears :-( It is stuck on that screen forever. When I push the reset button it resets and it gives me a sad mac (with sad-chime) when pushing the interrupt button.
Things I have tried:
Veryfied that the voltages were present and accurate.
I tested every line coming out of the SWIM point to point, that was looking good.
I replaced the SWIM with one from a dead Macintosh LC
I tested the machine with a GGlabs MacSimm.
I was able to verify with the diagnostic mode (https://web.archive.org/web/20190704003154/https://mac68k.info/wiki/display/mac68k/Diagnostic+Mode) that the ram is ok.
I tried pretty much everything I could think of, and I would really like to get this mac back up and running again.
I am thankful for any suggestions on this project.
