Re: Disk II 70 Tracks

["Bryan Parkoff" <BParkoff@satx.rr.com>]

    Do you want to develop software that will convert all 5.25" drives like
DOS 3.3 into 3.5" drives.  3.5" drives have an ability to read only 140KB.
It might work with copy-protected on 3.5" drives.  It causes Apple II family
thinking to read 5.25" images from 3.5" drives!  It will give slot 6 free
for additional cards.
