    Quoted from oldschoolbob:

    When I removed the headers I lost over a dozen solder pads. The lost pads were not connected but they just fell off.

    But the copper pads/traces are still in place right?
    I notice very often working on these Bally MPU boards that the factory solder comes off the copper traces because it never properly attached. The boards were not properly treated when they were solder flowed.

    Here's an example of a Bally MPU board I stripped the headers off just yesterday.

    You can see how the original solder has detached from the boards copper pads.

    Before installing new headers I clean the copper pads and pre solder tin them with some flux.

    Quoted from oldschoolbob:

    I didn’t get these for a game – I got them to rebuild. I enjoy fixing them.

    Bob, I applaud you for your interest in bringing these old boards back to life. Keep it up!
