Just throwing out an idea here:
There's always been a lot of discussion about multi-tasking on the Apple II which generally doesn't go very far... I think the reason for that there are very few practical applications for it and the resources of the Apple II are somewhat lacking.
How about instead of multi-tasking, some sort of pause-and-switch scheme? You launch a program in main memory and then (through some clever hacking of ProDOS) you hit a key combo that causes execution to suspend and you can then swap main memory into one of the other banks and launch another program.
Would this avoid the seemingly thorny issue of interrupts? Maybe it could use one of the annunciators as a signal?
