If you're talking about the product I think you're talking about, it
is called SoftSwitch, and it's from Roger Wagner Publishing (the
people who brought you Merlin and MouseWrite, etc).  They can be
reached at 1050 Pioneer Way, Suite "P"; El Cajon, CA 92020.  (619)
442-0522.

The actual limitation is that SoftSwitch will not switch ProDOS 16
programs in or out.  It works fine with ProDOS 8, DOS 3.3, and any
other environment that does NOT turn off interrupts but can be
preserved with a snapshot of the first 128K of RAM (and, optionally,
requests additional RAM from the GS memory manager, like AppleWorks
does).  I haven't tried it with Apple Pascal, but I suspect it
would work fine.

The reason interrupts must be left enabled is that you can't get
into the CDA menu to get to SoftSwtich and switch to another
program if interrupts are off!

Disclaimer:  I know & like Roger Wagner, but he's not paying me to
             say any of this.
