CP/M is alive. Very much alive. And the 48 years of life loom up only, if you take a closer look. A whole series of homebrew-retro-solder-it-yourself-diy-systems™ adorn themselves with CP/M compatibility ... and for a reason or two. There is a small but nice mini-universe of software at your disposal.

Kian Ryan - @kianryan on Twitter is usually running an RC2014 with CP/M, but was looking for an even more portable solution.

And so he piggybacked an Adafruit Micro SD SPI Breakout to a Pimorony Tiny 2040 and got RunCPM-Pi-Pico running on this little, neat thing.

Exactly your topic? Then have fun with his story.
