  Yes to all of the above. The MS-DOS software uses timing loops to
determine when the drive doesn't come ready (I have three versions,
there may be others) and times out on a fast machine.

  The Archive seems to run perfectly in a 8MHz bus, I have seen one out
of one run 12 MHz, but I strongly discourage running anything but memory
over 8MHz unless you're willing to choose add-in boards from a subset of
available units.
