I will definitely check out SunDog, if I can find it. I haven't yet decided whether I'm making a VM for version II or version IV, or both, yet. I want to be able to run code from Apple Pascal directly, so will likely start from II.5.

An interesting piece of trivia about the Apple III version of Apple Pascal that I learned from this discussion is that it apparently puts p-code and data in their own 64k segments, like you were talking about for your 65816 version.

A nit about Apple pascal is that it did rely on some custom machine language routines, but it may have been just for graphics.

That’s interesting about the Apple ///. Honestly don’t know much about that machine.

If nothing else, if you can hunt down SunDog, it can show the p-machine in something higher level than 6502 or Z80. But the IV machine is pretty different than the 1.5-2 machines.

One problem I had getting started was just trying to figure out how to read the floppy images that are available. I obviously didn’t try really hard, but it was enough to calm my sails at the time. Udo Monk has some nice images on his Z80 pack site.
