My lifetime project: building an 8-bit computer using Z80 CPU. This week I had a bad flu and could not do anything useful so I decided to dig up my old plans for this project. I first re-designed many things, like power, CPU-board, IO-board and so on (my old plans were around 10 to 15 years old). After some thought I realized: When I get even the CPU-board working, I want to display some stuff! So why not build the display adapter first. Plus I planned to build the adapter in a way that it can be used separately from the computer itself. Easy thing to start with.
