Turns out that the Stanford “Apple 1” is an unpopulated Apple II, rev 0 PCB. The only other unpopulated A2 rev 0 I know of, is the one that the Hudson Brothers just sold. As rare as this is, it would have been nice to find a bare board Apple 1. By the way, during this investigation, an archivist at Stanford Library sent me the best image I’ve ever seen of the front of a bare original Apple II rev 0 PCB. More on that in the next post.
