I’m continuing to experiment with alternative ROMs for the Planck, mostly as a way to learn more about the system.
I’ve just created a project on GitLab that hosts a port of Floobydust’s micromonitor. I’ve edited it to compile under ca65. It’s an interesting monitor. One of the interesting features is that it supports interrupt-driven receive with a buffer, along with delay-based send. In any case, if anyone is interested this is the link.
Best wishes,
Ben
