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.
