Aargh, a 32 bit ProDOS-8!

That sounds dangerous to me but the idea is great, I've always wanted
a ProDOS 8 support for bigger drives but that will prevent us from
accessing such drives from GS/OS and other platforms.

Instead of rewriting ProDOS 8, why don't you add a disk driver to
support bigger drives? That support may be limited to the physical
access not to the handling of a file system thus reducing the
interest, I don't remember exactly what that does but I really believe
the changes will kill compatibility. I'd rather write a GS/OS FST
instead of breaking what P8 does well.

Correct me if I'm wrong, I may have missed some ideas.

What did you do? Disassembly, addition of new device information and
re-assembly?
