I have Micropolis 1325's connected to an internal hard drive
controller on a Tandy 6000 under Xenix 3.02.00. The Micropolis 1325
is a drive with buffered seek, which means you can send it step pulses
rapidly, it buffers them and figures out internally how fast it can
work the actuator. This allows faster seek times than a fixed step
would because it can account for acceleration and deceleration of the
actuator assembly.
The problem, the step rate is stuck at the slow value that Tandy
decided to use and they didn't provide any obvious method to change it.
They give you a command, "drive" to set floppy step speed, but nothing
to set hard drive step rates.
Has anyone figured out a patch or other method of altering the step
rate to something more reasonable (fast) for a 1325?uhclem@trsvax.UUCP (07/23/90)

(Only restores step slower and that is a function of the 1010 controller.) Drives that are used with the 6000 *MUST* have buffered seek. <This information is provided by an individual and is not nor should be construed as being provided by Radio Shack or Tandy Corp.
