    Still looking for schematics for Apple color composite monitors A2m4043, A2M6020 and A2M2056. They are all pretty similar color composite apple monitors.

    I find it hard to believe the color apple II monitors repair manuals and schematics arent out there readily available. Macintosh sure,, but Apple II? Weren't these monitors popular?

    Unlike Macintosh monitors the Apple II monitors were documented in the Apple Service Technical Procedures (ASTP) for the entire Apple II line. Of course they contain nothing as useful as a full schematic, but you can piece together what is going on with a lot of their monitors from the diagrams they do provide and the parts list for each.

    Depending on the model you have to find an ASTP from a year in which your monitor was sold.

    The Internet Archive does not have all the ASTPs with some big gaps in time, but I think at least one of your composite monitors should be covered in there.

    You can see what other ASTP guides they have here:

    I hope this is in some way helpful, though you probably already found these and need a full schematic.

    Thankyou Rpiguy2. I have found practically nothing so far and i honestly did not know about these. Sure a schematic would save me but this is a great help too.

    The 9" monochrome is just called 'Monitor' ...A2M4090 ... there is no IIc in the name on mine anyway.
    I also have a ColorMonitor IIc. A2M4043 ... and could use a schematic.

    Yes the naming convention is atrocious. And Yes one of the monitors I am asking for help on is called the ColorMonitor IIc (and ColorMonitor IIe, and ColorComposite Monitor)
