Well I did plug the keyboard in backward and fried a 74LS00 chip on the keyboard. Fortunately I have spares in my stash. Once fixed and plugged in correctly, I get a monitor prompt after reset and can enter small programs. I only now realized that the monitor isn’t really the same as the Apple II monitor and I’ll need to round up or create a manual, since the Apple 1 operations manual only lists the source code.

The kitchen counter is the lab this week.

Next step is to solder in the edge connector and see if I can get a borrowed cassette interface to function.

One last editorial comment. For a long time, while working on this project, I really just didn’t feel very attracted to the Apple 1. It just seemed too primitive and lacking in features, especially compared to it’s offspring, the much more sophisticated Apple2. However, I now have to admit that I’m starting too develop a fondness for this straightforward machine. For one thing, troubleshooting problems seems to take half the time or less compared to the Apple 2.
