You shouldn't have to alter DOS 3.3 at all, but you could add to DOS a BYE command that restored the global page and returned to ProDOS.Is that still true for e.g., ProDOS 8 v1.9 and later, or GS/OS? (One of my tests is running The DOS Escape from GS/OS, and returning to the Finder.)
For vm02, I completely destroy LC2 and ProDOS continues to work (even with the appletalk network card). Of course it kills the quit code so I have to reboot, but it appears that LC2 is mostly available. Oliver has done a lot of investigation into using LC2 as well.
Also, this would have other uses: you can still access the MLI because the system page is intact. Not really valuable, but it could have its uses.Perhaps what I'll try to do is replace the INIT command altogether.What I *really* want to do is rewrite the File Manager to just issue MLI calls. With this, stuff could get pretty low-level into DOS 3.3 and still work on ProDOS. (And I want to try something with The Prisoner on it >:P)
I think you'll run into problems with prefixes and other ProDOS only features. I believe it also needs bigger buffers than DOS requires.
