In any case an
email from a kind gent has cleared up the mystery for me. The
connection method is 3M Scotch 9703 conductive tape:

http://products3.3m.com/catalog/us/e...er/output_html

"Tape 9703 is an isotropic, electrically conductive, pressure
sensitive adhesive (PSA) transfer tape. It is a permanently tacky
system consisting of a PSA matrix with aligned conductive particles.
These particles allow electrical conduction through the adhesive
thickness ("Z-axis"), but not in the plane of the tape."

I agree with the others that this is a VERY interesting product, but I
don't think that it was what was used on the calculator I worked on
many years ago. That stuff did not look like tape, and it certainly
wasn't tacky any more.

There must be something else that is suitable for OE use. Perhaps it
is ultraviolet curing.
