The RC2014 is a DIY Z80 based computer that talks to the outside world using serial comms. This means you need a serial interface to another computer in order to control it. Recently I came across the Pi Pico VGA Terminal board that does away with all that faff. Now, I could buy it, but…
I use a Raspberry Pi Pico and turn it into a serial terminal for my RC2014.
I found a real bitmap display for the RC2014 and here’s how I made it work.
I turned a Raspberry Pi 400 into a C devkit for the RC2014
