    Piggybacking a new ram on top of a faulty one should solve the issue. If not, the fault code should change enough to give a clue.

    Are you still having a Bong ? strange, as this kind of pattern is related to a Rom issue, can you scope the reset and data lines ?

    Mac lc 475 no sound

    Hi, i cut the head off the old capacitors first, then remove the legs. That way, there’s no pressure on pads. You can have a drop of sound in the first place, then a lack of it.

    Apple IIGS Repair Help

    Anything is possible. Don't know, but you can have several bad chips and the self-test is not accurate a 100%. The Apple IIc test Will stop at the first bad chip found, not giving the full information. Iirc the iigs memory is split in two.

    Apple IIGS Repair Help

    The best method is using a new chip on top of the faulty one, also called piggybacking. Always worked for me.

    Looks like a ram issue to me. Probably not related to the battery problem

    50 pin -> 80 pin SCSI?

    Yes, has been a long time, but yes it worked for me.

    Problem is some information is missing from the screen, so a 4 is present for sure, we can only guess the rest. Once again piggybacking is the way to go, worked a 100% for me. My guess is that maybe more than one chip is bad.

    Yes ram issue. As the code is not complete, hard to locate the faulty one (F7 or G7) piggybacking always worked for me.
