Yeah, it should be almost perfectly compatible with software that runs on a 64K II Plus, aside from things that called undocumented ROM entry points. As I wrote on my blog, the later version 1.21 of the boot PROM actually fixed some compatibility issues that prevented ProDOS from booting.
Thanks for the info, do you know how to get into the built-in LOGO interpreter?
