    Macintosh Plus reboot in a loop or vertical bars

    I did have them once but it not always the case. Its only the roms when there is a short to ground. The first time I tried to put a scsi connector in my plus I fried the roms but other than that I haven't seen a computer with normal config do that unless there is corrosion.

    SCSI drive won't spin up! Ideas?

    Real quick if you start to have the same problem again but its not the psu. The likely reason that i have come across is bed caps so look into replacing them while you can

    This Does Not Compute SE/30

    Really quick I know this is an SE/30 but I was scrolling though Dead Mac Scrolls and one looked similar to The Programmer switch maybe being stuck. It sometimes also has out comes like this one.

    SE/30 with graphics issue

    oh so it does it without the ram ok so it has to be roms or a connection issue

    Mac SE - checkerboard and repeated chimes

    Oh crap sorry let me think... It hast to be a resistor or a cap some analog part that takes a while to heat up right along the video out pin. It could be an voltage rectifier. I know a conman issue is the connector to the motherboard and it could need a cleaning use some metal polish I'll look into the situation you are experiencing.

    Macintosh Plus Internal Hard Drive *Mod*

    wait why is RST on the wrong side of NRC 5380

    Have you ruled out if its a bad ram card because if one chip on one card fails the whole machine wont boot and having issues that are rare to find a solution for online. What you want to do is check each ram card by pulling them out and testing them 1 by 1 in a 512 configuration. If that dont work try testing the cable connecting the AB to the MB it could need to be cleaned. And if all fails it could be ROM's.

    This Does Not Compute SE/30

    Um sorry but I don't know If you have not covered this yet but, I have two suggestions. I have had many compaq macs end up having corrupted screens. If I were you I would look up ram configurations and manual test each ram card in the SE/30 and another mac that excepts the ram cards. To me that board looks fantastic and should not be to tough to get working. Another suggestion is checking the cable from the AB to MB board to check if the pins need to be metal polished. With any SE I've seen it has not been a problem but with Macintosh plus's its a common occurrence so I would just check incase that its that simple. I have not ever seen a macintosh SE need a big recap unless it was completely cooked due to over voltage but due to the air cooling fan and good parts even the worse one's I've seen could be fixed. If you acquire some big problem it like every one else says would be the ROM's but I rarely see that and again the Macintosh would probable looked like it had been cooked over an oven the board probably would have battery acid all over it and would be screwed. In summary I would check the obvious before going strait to hard stuff thats my advice it will save you alot of time and work. BTW: when I mean clean the pins I mean the pins directly on the two boards and the connector I know you have already checked the voltages but its always good to see if your getting the best connection

    I had the same vertical bars so I thought I messed my plus up but when I turned the cut off down it booted so I dont know what thats about probably I have a crap cable

    Macintosh SE with horizontal lines, no chime

    Always start by re inserting the ram after cleaning each one with isopropyl alcohol. If that doesn't work try configuring the SE with 512k and check each ram stick by swaping them untill you get the machine working.

    Help screen shrinking mac plus

    So I have come across a problem with my macintosh plus and that over time the screen horizontally starts to shrink. I dont know what could cause this and im not home to do research. It might be the flyback but idk.

    Macintosh Plus reboot in a loop or vertical bars

    Another problem that could cause this is that your 12 volt line is low and that to test this just unplug your floppy drive and see if it boots. If it does there are alot of forums about how to fix the problem online.

    Macintosh Plus reboot in a loop or vertical bars

    I would turn down the voltage cut off and it should fix the problem which I think is a easy fix. Its good that its not your mother board I can assure you its not. I think the other AB just needs a recap and a little ajustment.

    Macintosh plus screen centering issue

    Ok so thats fixed but I still am haveing another problem I should have mentioned. The brightness knob does not work what so ever and there is no cracks in the solider, the sound issues, and the focus ajustment barely works either.

    Macintosh plus screen centering issue

    Ok ill try it now
