Manage to get myself somehow dragged into building Apple Is because I wanted a 6800 version. That was the start of trouble! So I bought 2 bare PCBs and planned to build a 6502 and 6800 version. Had I done some research before hand I would have found I could have bought many vintage computers for the price of the various parts of the Apple I and we're not talking date correct parts just the necessary parts. But at the same time I happened on an unloved more than complet Apple I reproduction that wasn't running. So I bid and won at a more than reasonable price, half as much as a working complete reproduction and less than buying the parts. Well I diagnosed the bad chip, a 2519 ($70+). I used a replacement board with parts that are available and I now can program like it was 1976. :-) I threw some quick photos up on: https://ushomeautomation.com/Projects/Vintage/Apple1/index.html Yes, the Commodore monitor needs a bit of TLC. I'll get to it ... eventually. ;-) -- Linux Home Automation Neil Cherry ncherry@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ
