This is a good learning experience for lots of us out here. Any chance of
scanning the printed material and posting , say on a.b.s.e?

Nope, sorry. I don't have access to the binaries groups, and in
addition, it's copyrighted material. I'm willing to make a very
limited number of copies, but not to post it.

The articles I have are old HP Journal articles, available in
"Inventions of Opportunity," copyright Hewlett-Packard Company, 1983,
ISBN 0-9612030-0-5. You may be able to find that in your library.
The articles in that book were chosen to represent seminal ideas and
products that opened new horizons, so the SRD items are as much for
historical interest as for technical info.

You'll find a little more modern technical info in HP AN-1054,
available at http://rf.rfglobalnet.com/library/Ap...s/1/An1054.pdf.

Cheers,
Tom
