One of the things that I remember about Apparat
(slightly before that)
was that NewDOS (was it only in NewDos80, or all the way back to
APRDOS?) gave the user the capability to set the step time, to be able
to take advantage of the 5ms step time of the Tandon, etc. drives,
rather than have to always step everything at 40ms to be able to
handle the original SA400 (the original drive shipped with TRS80).
IIRC, NEWDOS/80 allowed the step rate to be changed on a per-drive basis
using the PDRIVE command. In fact, you could change an amazing number of
parameters for the drive or the filesystem format using that command.
I don't think NEWDOS had such a command, though there might have been
ZAPs (patches) to change the step rate globally.
