    Anyone interested in salvaged chips? (LC I)

    I found an LC (LC I) that was a bad case of battery leakage and beyond repair. The leakage was confined to one half of the logic board, however. I did my best to remove some of the healthy-looking chips. Is anyone here is interested in them? Given their dubious history plus the thermal stress...

I completed the de-capping and am now assessing whether or not I have the skill to restore the board. I have limited tools and experience with such...

    Mac SE repair: what's the best bet, after the analog recapping?

    Hello all. Avid readers may recall I recently repaired an SE FDHD. Along the way, I noticed some infrequent, momentary narrowing of the CRT image, so I recapped the analog board. It seemed to be fixed so I reassembled the case and declared victory. But last night the screen had a period where it...

    SE FDHD: SCSI woes

    Hello all, good day, TL;DR : In sum, I'm trying to resolve a dead HDD in an otherwise promising Mac SE FDHD. What follows is a description, some ideas, and a question about the 53C80. -- A neighbor found her husband's old SE FDHD in the attic and I offered to check it out. It is a late model...
