Wow. A look at how the Sinclair ZX80 works.

"[T]he first thing to know about the ZX80 is that, unlike most other computers, it's main job is not to run your code. That's very much a side task. The thing it spends most of it's time doing is drawing a picture on the TV screen. [...] Unlike most other computers of it's era, it doesn't have a video chip."
