Jay,
When I was at HP many years ago (left in 1987) I ran across a guy (of course
I can;t remember his name) who collected and repaired 7970's as a hobby.
I'll try and dig up his name. Ping me if you haven;t heard anything from me
in a couple weeks. BTW, what's your email address - the list hides it from
me.

Subject: HP 7970E tape drive woes
Greetings and a question for the list....
My HP7970E tape drive is *sick* (plus I just blew the 30v supply in my
HP2100A, but that's a whole other story about me and Murphy's Laws on
getting HP2000 Access up and running). Do others find that resurrecting
these old systems causes a propensity to drink excessively? *GRIN*
On to the question... The 7970E passes all the mechanical tests via the
switches internal to the unit (tape speeds & motion basically).
It fails the
read/write test portion of the diagnostics (but does pass interrupt/DMA
tests so I suspect the interface boards are ok). Is anyone particularly
familiar with these beasts and can suggest a course of action? I have all
the "theory of operation" and "maintenance" manuals (as well as
schematics),
but they are two 4 inch thick manuals and a lot of it is way over my head.
Hopefully someone can point me in the right direction to at least get me
started - or better yet, anyone have a 7970E up and running that would be
willing to loan me some boards to test mine via boardswapping??
Thanks for any info (or condolences & empathy) anyone can provide!
Jay West
