Many of your questions will be answered at:

    http://www.hpmuseum.org/

which is the on-line Museum of HP Calculators.  The museum's
CDs include scanned manuals for many HP calulators.  There's
also info on rebuilding battery packs (I've done an HP22, and
will one day put the photos onto the web).
