Hi guys

I used to have an old HP-85 hulk out in the barn, and also some of the tape
drives (not necessarily from  85's though)
I just went out to see if I had any of them left, but I'm afraid they're gone

What I have seen on many of those is just what you are talking about.. the
rubber in the capstan pinch-roller turns to sticky black mush.  I've got a
couple of serial data analyzers with those in them, and I went to try them out
last year, and it just ate the tapes and made a huge mess!

I think there is a HP with tape drive in the scrap yard I frequent. Next
I am out there (waiting on better weather) I will look.

Otherwise there is a person who rebuilds phono idler wheels who post
on rec.antiques.radio+phono. You could try him for a rebuild.
