Hello everybody, I carried on the development of the firmware of my LM80C Color Computer and I'm happy to announce the availability of a new major release, the version R3.0.

With this release the computer is now a stand-alone in every way: it is now possible to move the cursor anywhere around the screen and digit commands and statements freely. When you'll press the RETURN key the kernel will analyze the on-screen text, acting as the old home computers from the '80s.

Another big change is the SERIAL statement, introduced with the version R2.15 of the firmware, that let the user to open/close the serial line.

Here is a little demo of the new functionalities:
