Here’s the latest PicoCalc version 6.01.00RC22. It includes pre-compiled PicoMite2 and WebMite2 .uf2 files. I’ve run both of them on my two PicoCalcs so I know they’re good. If they don’t run on your system, you can always compile the source files. If you run Windows, load the WSL subsystem and then follow the instructions on the GitHub site. If you run Linux already, just follow the instructions on the GitHub site. I’m no Linux expert but I was able to follow the instructions perfectly.
This PicoMite2 version still has the serial port bug of not being able to send data out the serial port, The WebMite2 version doesn’t have that bug.
