recommended that you try and find a QD drive but several people have
correctly (and vigorously!) pointed out that a 1.2Mb drive does use 80
tracks and that you COULD use one of them. (once you over come the possible
double stepping and write-strength pin select problems!) The problem is
that they use a different magnetic field strength and I've had that led to
That's what the density-select pin is for. In one state (deasseted?), the
write current is correct for standard DD media (360K disks, etc).
There really should be no compatibility problems reading/writing 80
cylinder [1] DD disks in a 1.2Mbyte drive, provided you use it correctly.
There isn't. also, there is no problem with writing 80 cylinder single
sided disks in them (dec rainbow format) the HD drives step down to the
lower write strength when told to by software, be it RainDOS (the driver to
make a 1.2 MB Disk drive on an IBM compatible write dec rainbow disks or
commercial products to do media translation
