1.2MB drives where 80 track, double sided 15x512byte sectors per track, 
as used on the IBM AT. On the AT they could also read the 360K 40 track 
drives by double stepping the heads.

As with 1.44MB drives they may be usable on the CoCo/Dragon in double 
density mode, as 80 track drive giving 720K/disk.
