    I have built the David Tait Pic programmer and have used it for a long time.
    Suddenly I can't get it to work properly. It seems unstable and will only
    program the first adresses the rest are filled with 3FFF. I have rebuilt the
    circuit I have tried different computers I think I have tried almost
    everything, it doesn't work!

    Any ideas?

    tried a different cable?

    is the PIC device still good, has it failed after multiple writes?

    ZIF socket worn out, one pin gone bad
