    I've made a start on the +2B version, but I need some help. Anyone with a black +2 issue 1, 2, or 3 board. Can you check some things out to find what is connected where? Just a multimeter for measuring continuity is fine.

    For 48K and Spectrum + I have seen rubber pads from broken joysticks recycled before. Does the job just as well.
