I have a new, old-stock printer for the HP85, still in it's bag and box.
Is there any interest in it or is it junk?


Not me. I've got one.

Some many years ago now, I organized a group purchase from PIC of
drive belts for the printer and also developed a technique for
re-rubbering the capstan roller in the tape drive. I would
appreciate getting your printer


That was the problem with much of the HP mechanical hardware. The
rubber composition just didn't last and would eventually decompose
into a sticky mess. For example, this is my reconstructed HP-65 mag
stripe reader drive wheel using a slice of clear vinyl tubing.

Incidentally, the most difficult part of this exercise was neatly
cutting the hose to size. I had to use a razor blade or a scalpel.

The tape drive roller in the HP85 was susceptible to the same rubber
deterioration.

I fixed two using the same clear vinyl tubing trick. Sorry, no
photos.
