  • Frustrating Gallag Board

    Here's the repairs that I done for a Gallag board.

    000000's across screen. Replace socket for ridder board.

    Board now goes to RAM OK ROM OK and keeps rebooting. Remove and check 2114 RAM chips on CPU board. All tested OK replace with new new RAM chips and socket them.

    Remove and replace socket for CPU 4.

    Board now displays RAM OK ROM 11. Remove and replace ROM socket at 4J.

    Blank screen. Dead crystal. Removed and replaced.

    Working board.

    On another Gallag board only had a yellow screen. Replace 74244 chip on ridder board.

    Cool
    Another 2 saved from the tip
    ...maybe, but then again "maybe" covers a lot of things, like: maybe Michael Jackson really is LaToya in drag, or maybe if Dorothy clicks her heels 3 times and says "There's no place like home" while she is at home, she would telefrag herself..." - MadMikeAU
