I had a chance to look at such an Apple II Plus clone that wouldn t boot into BASIC. It beeped and displayed Continue reading Easy repair: unmarked Apple II Plus clone

Smoke coming out of drive There is a real chance that yours too might emit magic smoke when you turn it on for the first time in decades.
