Good evening,
I got a Macintosh Classic M1420 back in mid-June to use it for writing novels and scripts (movies, TV shows, etc) and either print them (need to replace every capacitor for the StyleWriter printer) or save to diskettes and copy them to my main laptop to view them while away from the Classic.
Unfortunately, I hit a big snag: the floppy drive doesn't want to write or format diskettes, but it ironically reads from them just fine and I can copy files from the diskettes to the 250MB hard drive (which works, by the way). I tried two drives (internal) and they both act the same, except the original one stopped working altogether and the replacement kind of works. The alignment is fine and can only read diskettes I wrote from my Windows laptop using a USB floppy drive and HFVExplorer.
I already cleaned the logic board, recapped it, patched two traces, and it boots happily from the HDD, FDD, and ROM. Another issue is the RAM acts weird and I already swapped the bad RAM SIMM-30s with spares I had in my container filled with RAM and I'm not sure if the CASPAL chip is failing or I missed something. As for the floppy drive, I'm not sure if the SWIM is bad or not.
I do have a heat gun for the soldering station I have, but I cannot find the SMD removal kit anywhere for easy chip removal. Has anyone had success at getting the chip back from the dead? The traces in that region to the floppy connectors and other places are all fine, though.
