Design Retrospective - Making an 8 Bit pipelined CPU

I asked for some question and got a far bigger response than I expected. This is my longest video to date (it took an age to edit). I'm expecting most people to use the index to skip to answers they want to see rather than sit down and watch it like a feature.
