Aside from the boot sequence, the only changes that would be absolutely
required would be some code to load the character generator.
Hmm, that would be interesting. I'll have to look for one of those.
I've seen patches for DOS 3.3 to work with 3.5" floppies on a // but
haven't seen anything for it on a /// before now. If you ever get
around to checking out the changes tell us about it. I once hacked
an Apple // OS called Apex which was only out on 13 sector format
at the time to work with the 16 sector format when it came out.
That was fun.
