Jason,

Yes, I plan to do the iPDS-100 sometime in the future.  I have an 
iPDS-100 here which Richard Main modified to use 3.5-inch drives. It is 
in the queue, but behind several MDS I/II machines I am currently 
working on.

Those MDS 8" floppies were really something.  Going to 5 1/4 inch on the iPDS was so much nicer, but man, could those iPDS disk drives make some noise when the disk had an error and it did a track 0 recalibration of the heads.  You *KNEW* that you had a bad disk !!!  Fun times ...
