I threw this together:

This contains a program I wrote to cram DOS 3.3 into 256 fewer bytes (by
disabling format and revectoring a couple patches) so that ProDOS need not
be overwritten.


...and up next: cats and dogs living together, followed by mass hysteria. :-)

Combine this with a dual-format disk (a Nibble article featured a program
that put DOS 3.3 and ProDOS on the same disk) and you'd have one disk that
could boot both (would probably boot ProDOS first) and run programs for both
of them.


Actually, I have such a tool (it's on Extra K).
The real trick would be running ProDOS stuff from DOS 3.3 (the - command stuff), but I got the Selector source and might be able to glean some info from it.
