I missed the David's  post until now..

  I wonder if the Unidisk could be used as a co-processor,
doing non-disk access computations?

  Could you set it up as an audio streamer..  or a video
player for the GR screen?  Does the unidisk 65c02 have
direct access to the apple bus, or does it communicate
through the slot through Cx00 I/O locations?
