Re: DOS 3.3 for 1.40 MB disk, for a system with non-working 80-column code?

["Joel" <joelbuckley54.nospam.@hotmail.com>]

Shouldn't be that hard.
You might try to just use one of the patched versions of DOS3.3 for 800k
disks.
Whether it uses ProDOS block calls or smartport calls, it's a good chance it
would work
on a 1.44 disk (even though it would just use the first 800k)
But those 800k would be readable on an IBM

 Why waste 240k?
Do 3 400k disks and 1 240k or do 4 360k disks.

The question is-do you map the extra pseudo-disks as other slots and drives
or use the volume parameter?
Using V or drives 3+4 gives you more flexibility (like running on multiple
FDHD drives simultaneously) if you're doing custom programming.
Do you want to be able to access all of the disk at once, or is it ok to be
effectvely swapping disks, having only the volume you select active at a
time, ll appearing in the same slot and drive,

But if you want greatest compatibility w/ old programs , most didn't use V,
most will limit you to drives 1+2, and some may not even allow all of slots
1-7.
And of course some stuff is hardcoded for 140k disks.
