Had some #CPM 2.2 fun last night!

I managed to get #RunCPM compiling in the Arduino IDE, and successfully running on my #Adafruit #GrandCentral board.

It involved correctly installing the required board manager packages, and the Adafruit fork of the #sdFat library.

I also prepared a 512MB microSD card for the Grand Central.

After connecting my Grand Central, tweaking the sketch and setting the right target board for it, it just worked and I had an "A0>" prompt in PuTTY 🎉

A small Update for #RunCPM v6.9 for
#Pico/#Pico2 and #Windows on my github
https://github.com/guidol70
- New cpm.h which supports SPEED . COM
This makes the emulation slower
SPEED 0 does disable it
You can test
SPEED 500
SPEED 25
