There exist several software packages that claim to greatly increase the speed of Apple DOS 3.3. (Pronto-DOS, Diversi-DOS, etc.) An advertisement for Diversi-DOS states that "Apple DOS 3.3 takes 18 disk revolutions to read a single track, whereas 'Diversi-DOS' reads or writes a track in just 2 revolutions". It it true that DOS 3.3 is this inefficient, or is there some error detecting, error correcting going on in DOS 3.3 and not in Diversi-DOS? Does anyone know what types of tricks Diversi-DOS could be doing? Though this example concerns the Apple ][, specifically, could some of the speedy tricks be conducted for other DOS'es ?
