"The programmer had to do everything: Write the whole operating system from scratch, design all the graphics, write the tools to do the graphics, create sound tools, and do the sound design – everything from scratch for every game….I’d write the code on programming sheets and turn it in to the typists who’d type them in to a DEC computer, then give us a tape with the resulting compiled/linked program. We’d then take that to a blue box [which used the FORTH programming language] for debugging. We’d mark changes to the code on a listing, give it back to the typists who’d edit our files and give us a new tape. Repeat ad infinitum."
