Thanks, I ordered a zoomfloppy today.
Regarding the 1571 I should just replace the linear power supply with an
SMPS.  If the fuse is blown there must have been a reason. There is a meanwell
that is a good match.  And there are 4 electrolytics on the logic board that
should also be replaced.  
If I later find the heads are bad, I can use the SMPS for a different
project...
