AppleVision Disassembly

In 1977, Bob Bishop wrote a clever little Apple II demo called "APPLE-VISION". It was initially distributed on cassette tape, and was included by Apple on DOS System Master disks.

The program uses a clever trick to embed machine-language code inside an Integer BASIC program. When the program first loads it looks like a couple of lines of HIMEM/LOMEM/POKE statements followed by garbage. After you run it once you can see the actual program.

The disassembly is split into Integer BASIC and assembly-language components.
