As far as I can tell (although I haven't prowled all the way through the latest 25 pound box of documents), all the HP programs and docs have been scanned. The rest of the stuff is TI-59.
In the HP corner, there are:
9 documents and
279 programs (43 HP-41, 202 67/97, and 34 miscellaneous)
I feel sure there is a LOT more information out there, especially old HP newsletter like Calcu-Letter and PPC Journal. If you have any of these, please consider sending them to me for scanning.
