Here is a list of HP calculators for those who are historically minded. By the way, if you have an old HP calculator that you really don't want, there are those of us on the net that would like to buy them, hint, hint.

Just for the record, the HP95C was a machine in the 91/92/97 series which was a 200-step programmable (continuous memory) scientific with LED display, thermal printer but no card reader. List price was to be around $500. The keyboard included global label A thru D keys and keystroke programming like the 29C. Prototypes were made and manuals were printed and then the project was cancelled. A unit was shown at HP in 1981 at the Corvallis Conference (it was in Bill Egbert's office). The next HP conference will also be in Corvallis on Friday, August 2nd through Sunday August 4th, 1991. Tentatively there is going to be an HP plant tour on Friday, with two days of talks to follow. It should be a blast. EduCalc advertises that if one sends them a self-addressed stamped envelope marked "Conference '91 Info" in the lower left corner, they will send out official registration information when it becomes available. As always, EduCalc is at 27953 Cabot Rd, Laguna Niguel, Calif 92677. Jake Schwartz

The HP-11C actually has variable memory partitioning much like the HP-34C. The 11C started with 63 program steps and 20 numbered registers, and you could convert registers one at a time until you had 203 program steps and no numbered registers. The HP-11C was the first HP calculator I ever owned; after that I upgraded to an HP-41CV with the X-functions and Time modules (almost a CX), and now I have an HP-48SX. I would be fascinated to see some information on the original HP desktop calculator series that the HP 9100A belonged to. I have heard of later machines similar to the 9100A that had LED displays instead of CRT displays. I have a much-loved 9100A that I saved from being junked and which I suspect may outlast my other HP calculators and my HP 150. It's almost as old as I am and it's happily churning away on a table here at home. -- Steve VanDevender stevev@greylady.uoregon.edu "Bipedalism--an unrecognized disease affecting over 99% of the population.

Jake S. mentioned the HP-95C, which was kind of like a 29C in the 90 series case. Well, since it was never made, it was not on the list. (Never made in the sense that no one could buy one.) He mentioned that Bill Egbert had one on his desk: it was Bill Egbert who gave me a clear plastic back for my HP-67! You can see all of the insides of the calculator. Those were great days indeed... Thanks Jake for refreshing my memory about the almost 95C! Dan

I believe the HP 19B and 19B II have 8K of RAM, not 32K. Stephen J Thomas sjthomas@cup.portal.com
