I'm in that mode - attempting to resurrect an old HP 5420 Digital  
Signal Analyzer (aka spectrum analyzer, albeit low frequency) to save  
a couple of thou on the purchase of a used equivalent.  I'm trying to  
find Vol IV of the documentation set that has the schematics for the  
beast as well an image of the control tape - the unit boots from an  
internal tape. The cassette bands have gone south, the cassette  
capstans have turned to goo, and it looks like the tapes themselves  
are failing.

Any help or referrals will be welcomed.
