In 1983 Geoffrey J. Crammond published the flight simulator Aviator for the BBC Micro. 3D Vector graphics. In 1983. As a reminder, Elite came on the market only one year later.

So it's no exaggeration to say, that Aviator was groundbreaking - in terms of graphical capabilities - on the BBC Micro.

Today - almost 30 years later - this causes at most a yawn or a shrug of the generation 'Nintendo Switch'. But who cares? [Kids] 😋 

Marc Moxon is obviously fascinated by the topic. (We like you, Marc.) He disassembled the machine code, documented it, and made it available here on GitHub. The source itself can actually be assembled into a working binary using an assembler, so we're talking about the real thing here.

You have too much time and are curious how the 6502 was persuaded to do this feat? Then you will have lots of fun.
