Still gathering parts – and emptying my bank account. Hopefully, by the end of next week I’ll have everything but a few commonly available parts in hand. I’ve also borrowed a cassette interface PCB, which I will need to build up in order to test the expansion port. I have a parts list for the cassette interface and will order those parts along with the last parts for the motherboard.

I keep finding little discrepancies between my PCB layout and the original. One recent example is on the silk screen under the power and video connectors. Based on the Apple II, I assumed that there was a silk screened box around the holes for those connectors. However I found an image of an original board that does not have those connectors installed. Sure enough, there is no silk screened box around those connectors. These sorts of changes are easy to make once the difference is discovered, but determining how the hidden portions of the original board looks, can be difficult, if not impossible. I’d part with a bit of money to get a hold of a good X-ray of an original Apple1.
