    I recently purchased a Macintosh 512K.

    I turned it on and it beeps and goes to a sad mac icon.

    The error code is 021000.

    Is there a guide that can tell me what that error code means?

    It would be great if it was something that could be fixed.

    Thanks everyone!!!

    Yup. That would be it.

    Now you need to desolder the RAM chip at location G9, find a working 41256 chip 150ns or faster and solder it in.

    You might want to put in a socket while you're there...

    Try taking it to the Apple store, that would be a laugh.

    ^^I've always wanted to make a youtube video of doing something along the lines of that.

    Sad Mac on PowerPC macs?

    Hello,

    Does the sad mac appear on PowerPC G3 and early G4 systems? I believe one time I might have seen it under OS 8.6 with my Sawtooth.

    I actually considered doing that.

    If it was in working condition, I'd take it in just to get a picture of it in the store.
