I am in the process of restoring an Apple ii europlus. I think I have everything ready to start the diagnostics (including a second working example which I came across recently). From information provided on this forum and a few other places, I have a good idea of the steps to take. I just wondered if it would be worth me purchasing a clone motherboard (which I see floating around on ebay) for substitute chips or are they not compatible with a genuine board. A friend of mine suggests that one of the roms may be defective, and I am a little worried about popping chips in and out of my working machine (which was hard to come by!) to help with the diagnosis.
Thanks for any advice you can give.
