I've got several disks from apple called BASICS that will allow a dos3.3
system to boot up and manipulate dos 3.2 disks. The only dos3.2 disk I've
ever seen was/is a diagnostic disk from call-APPLE that i got in a box of
materials i got from someone. Prodos can be used with any apple ][ with 64k
and an autostart rom. There is a bug in version 1.1.1 that can trash track 0
but I've never had it happen. Later versions do not have this problem. I
think it's prodos version 1.8 (or is it 2.0) that won't run on a ][+ anymore.
