    Apple IIe Resistor

    Nevermind, There's a button labeled "Int/Ext Sync" and it was on external. That was stupid. The beeper speaker still isn't working though. When I do the self test "Kernel OK" is the result. It used to be "System OK". If the Kernel is ok, does that mean other components are not?

    Apple IIe Resistor

    You and Callan were right, The PVM's horizontal sync was off. I'm going to adjust. The other II is the first one with the broken capacitor.

    Apple IIe Resistor

    I've always used this monitor, so it should be fine. The beeper speaker doesn't work as well.

    Apple IIe Resistor

    Alright, It displays nothing and has no "Beep". it occasionally displays this: As for the RAM, I'm a complete noob.

    Apple IIe Resistor

    One of my apple II's is not working and I believe this is the cause: I tested the resistance of the other resistors under the other IC's and they're 5 Ohms. I'm not entirely sure how to find a direct replacement on Mouser so I'm asking for help. Thanks.

    Apple Tape Back Up 40SC Not Working

    Turns out the wheel is just metal, I've looked at the apple cartridges for this and they seem to have a deeper cutout than my cartridges. I'm going to Dremel out some plastic and see if it solves anything...

    Apple Tape Back Up 40SC Not Working

    A rubber wheel that's supposed to move the tape in the cartridge has no grip, its hard and smooth. The tape isn't moving so I guess the drive can't find the BOT...

    Turns on now, I'm going to hook it up to my SE.

    Apple Tape Back Up 40SC Not Working

    No, I did not. There was a chip in it, so it probably needs replaced anyway.

    Apple Tape Back Up 40SC Not Working

    I put the resistors color coding through a calculator, its a 3.3 Ohm with a 5% tolerance. Ive been looking on mouser and can't seem to find a replacement, could I have a little help please?

    Apple Tape Back Up 40SC Not Working

    Since the PSU is identical to the HD20SC I'm going to use a video by JDW on his.

    Apple Tape Back Up 40SC Not Working

    It Looks fine but there are some wiggly components, 3 capacitors and a large resistor. One capacitor is a solid plastic block (Last picture, being pointed at with screwdriver) Here are some pictures of the PSU:

    Apple Tape Back Up 40SC Not Working

    The Power supply seems to not work, I've verified that power is getting to the board by checking the voltage across the fuse, other places on the board have power also but it's not getting to the connector.
