    I collect older Macintosh computers and recently my Aunt and Uncle gave me a Macintosh 128k they found in their garage. I have been doing some research on the error code that generates on starup, 042080. If i am reading this correctly does this mean that I need to replace the memory chip in F7 and F12?

    I believe that would be RAM at locations G10 and F12.

    Though I'm not sure if the memory test halts on the first error encountered or is able to report two locations at once.

    I'd be checking the +5v rail first and then having a close physical look over the logic board. If it has a plug on memory upgrade, that could be the cause.
