New subject: Wanted: Source for plotter pens

Eric Bal has a wealth of information on his web site
(http://www.ebbsoft.com/) concerning HP series 80 computers.  There are also
links to suppliers who might be able to supply new belts.

Good luck!

I would be grateful if someone on this list could help me.

I have a somewhat old-fashioned colleague who still uses an HP-85B.
This morning he came and asked me why the paper advance on the built in
printer wasn't working, what was he doing wrong?

He had borrowed an old HP-85 from another section (who had thrown it
out, apparently - it had a red sticker saying "Equipment not to be
used"), but this also wouldn't advance the paper, so he had concluded he
must be getting something wrong.

I tried a couple of times to no avail, so I took the lid off.  (Why do
they have to make the tape eject button so huge?).  Not much poking
around to discover that the toothed belt that drives the paper advance
had perished and snapped.  The rubber was mostly in dust all over the
place; the strengthening threads were wrapped around the drive gear on
the motor.  The smaller toothed belt that drove the print head was also
very ropy.

So, we opened up the other 85.  The same fault, with the remaining belt
in worse condition.

To conclude, then, does anyone know where to get replacement belts, or
what the HP part numbers are, or any other useful information?

Philip.
