Any suggestions, ideas, criticism?
I don't know much about Frances, never had one. From memory, which could be rusty since I hadn't seen anything about Frances for at least a decade now, thre was a separate memory card module for it, and they did something weird with a couple address bits that prevented some things from working normally, maybe Mac emulation had problems with it. But it's a start for what you're interested in, and I'd recommend googling for more info about it. There may be some stuff for it on aminet as well, but I just grabbed the first link that came up for you. I think I came across a bare PCB for it in a pile of stuff I got somewhere, the CPU module only I think, but don't know where it might be now. It was the long skinny 68000 style though, not the squar one I think the a600 has.
