The problems are with the different floppy controller: the WD 1772
(Atari) and NEC 765 (PC) are equivalent in reading/writing standard
floppy disks (9 sectors of 512 bytes per track). They are not the same
in recognizing copy protection shemes...

Of course it is possible to connect a 5 1/4 inch drive to the ST.

The ST has a standard Shugard bus (with nonstandard connector :-).

It is easy to install a 80-Track 5.25 inch drive.
There is a problem with 40-track drives: the ST issues a step impulse
every 3 milliseconds. 40 track drives need about 6 millisaconds for a
step.

The seek time can be changed by patching the drive parameter blocks, but
the adress varies from TOS version to TOS version...
