Watch as I turn a two line Python code into two screens of Z80 assembler, with the added fun that after making it work there’s no way to save the program!

I’m a programmer, the CPU is a mystic black box that gets fed instructions. I’m trying to learn and work out what the CPU really does.

I managed to get CP/M working on my RC2014 kit and then had some fun programming in Pascal, a language I hadn’t used in over 20 years.

Introduction I am learning Z80 assembler, with the intention of building my own Z80 based computer, and also learning how to write ZX Spectrum games. The two seem good projects that go well together.
