    It seems that
all of my 9-track drives are nonfunctional now.  At
 least two of them worked when put into storage; I'm very displeased.
 I've given up on them for the moment and am going to try to get a
 TK50 or TK70 working in the system. 
 I mentioned this place back on 5/06, but I'll ask again.
 Where do you get repairs on old 9-tracks?
 Back then I'd bought an M4 9914, an Overland Data 5622, and an HP
 88780
 in the hopes that one would work but none did.
 After a few months of trying, I eventually exchanged emails and
 a phone call with 
http://www.comco-inc.com/ in the hope of getting
 one of them fixed.  I never bit the bullet on shipping and
 repair costs, though. 
 
   Where to get repairs?  I have tools, test equipment, and a service
manual for my HP 88780... ;)
   The 88780 is a fairly modern device as 9-track drives go.  It has
extensive onboard diagnostic capability.  Do you have the docs to be
able to go through the test procedures?  That should narrow things
down quite a bit for that tape drive at least.  I'll be doing that
soon myself.
