Re: What is the best DOS disk to use?

DOS 3.3 was the primary Disk Operating System used by early Apple ][ systems and was designed to run on 143k 5.25" disks only.

ProDOS is a descendant of the Apple /// SOS system and offers considerable improvements over DOS 3.3 in the areas of file management, mass storage support, performance and reliability.

Best DOS

I only use DOS 3.3 for some old game disks and utils.

All my newer applications, utils etc. are ProDOS - mostly because I use a CFFA card.
