Tony was very helpful when I was repairing my HP
9830A.
It had multiple faults, I had to change a lot of TTL ic's.
You can see some of the 'war pictures' at www.flickr.com/hp-fix
When fixing the platen of the HP 9820 I used precision tubing and not the
shrinking tube.
You can read those fixes at the page on the HP computer museum site
www.hpmuseum.net
If you need some cards to test the reader let me know, I think I can miss on
or two..
I also have most of the TTL (standard an H-TTL) and Bipolar PROMS, used in
the HP 98X0 series, stocked, so if you can get an IC let me know.

Thanks Rik, those photos are great.. I'm going to have to put this project on hold
for a while, but I'm sure I'll be in touch at some stage.
