Ben Heck's Apple 1 Replica (2)

Ben continues to create an Apple 1 Replica. In the previous episode, he built the core of the Apple 1 - a 6502 computer with a CPU, ROM, RAM, and a few address decoders. Today Ben works to get some input/output going with an updated interface using a Propeller micro-controller. He can test the new interface by hooking up a display and keyboard.
