   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...
