Hi David, 1. It should be an easy exercise to turn USART1 into your AmForth speaking port.
2. Most of us, I guess, download/upload snapshots as you do even with a single board since when messing up things using MARKER to backtrack usually doesn't work and recompiling everything to get back where you were... simply takes too long. 3. When having multiple boards that's not even a question. I got so tired replugging my JTAG pod to resurrect the BOOFA project https://github.com/wexi/boofa.git and patched AmForth to make it compatible. Matthias considers it a hack but I am patient :-) Cheers, Enoch.
