I don’t know how I missed this, but…

> Hello,… Newbie here. I just made myself a port of RunCPM for the Picocalc (RP2040). Maybe someone else is interested by this work, so here it is : [picocalc\_runCPM](https://github.com/theflynn49/picocalc_runCPM) I just put together some other people’s work, so I didn’t do much, but if it doesn’t work, I probably broke it. Be indulgent wink Rgds

This works pretty well. The later versions run in 80 columns, but it takes a bit of work to get used to it - but it does work. I was able to get into WordStar, and actually able to read the screen.

On my PicoCalc (Pico 2W,) it is available as an optional firmware on version 2.3 of Pelrun’s UF2 Loader ( [UF2 Loader release](https://forum.clockworkpi.com/t/uf2-loader-release/18479) ). It loads fine, and runs great. With the highest speed version, it emulates a 32 MHz Z-80, and the SD Card feels darned near a gazillion megabytes.
