The simplest way to accomplish this would be to modify Paul Guertin's ADT such that it reads/writes only 13, not 16, sectors from each track. Since the source code to ADT is available, it's quite feasible to do this. But which Apple II emulators would be able to handle 13-sector .DSK images? The only way to deal with 13-sector disks on the emulators that I'm aware of is to store them as .NIB files. And ADT cannot handle .NIB files.
It may be possible to alter EMU][ to support these files, detecting by filesize. (I'd like this feature, personally. And perhaps emulating a ROM-switched 13/16-sector disk ][ controller card like the one you mention in your other post might be a nice touch, with a keyswitch - I could reuse the 40/80 switch, as they never coexist anyway! - to switch 13/16 sector mode!)
BTW, I'd like to see images of DOS 3.1 and 3.2.1. ~.^ I think I spotted two 3.2 masters (INT and FP versions) on Asimov; if there's variations, those would be interesting too (and, a pure copy of the 1983 system master for DOS 3.3?)
