    Default TRS-80 Model 1 Video Service Manual #26-1201

    For any TRS-80 Model 1 user/owner, I stumbled across a paper copy of the 26-1201 Video Service Manual 26-1201 in my file cabinet.
    I was originally looking for my SAMS Photofacts folder on the Black & White TV that was the basis for the Model 1 Monitor. I've still
    not located that SAMS Photofacts folder. It's still hiding in a box, after my move.

    There is a .PDF file & .PIZ file (.ZIP renamed - of the 400 x 400 DPI TIF scans) Download, Save, Rename to .ZIP, extract and use as needed.

    Thank you! I've been looking for this for awhile. The waveforms are particularly interesting as they are not in the SAMs model I manual PDF that I have and should be helpful in troubleshooting.

    Thanks! I've stashed it away, and I hope I won't need it for a good long while.

    @ ldkraemer

    Thanks for the Model 1 Video Manual.
    I would have been helpful about a year ago, i had used the SAMS version to fix the Plugin Input Board
    I borrowed a spare from Ian Mavric, and found that Both boards were different in the components used.
    The wave forms are a big help

    Thanks Again Ray
    If it ain't Broke then PLEASE DONT fix it.
