How were video games written in the 1980s? Not in Python or Java or even C / C ++, but in the only possible language: machine code! Through the Commodore 64 (physical or emulator) we learn together the basics of how to program a computer without the modern obstacles (operating system, web,). These classes are also ideal for students interested in embedded and / or other low-level systems. About myself: In the 80's I was a professional video games programmer working in the UK. Since then I have added 30+ years of software engineering experience.
