1. Bill Butler
Title: How I use my HP-XX
Synopsis: An HP48/49-centered user-level programming odyssey is sketched with attention given to the development of an effective user protocol, a couple of examples of extreme multi-machine calculating and perhaps 1-1/2 HP49 bugs.
2. Martin Cohen
Title: Programming the HP-33s
Synopsis: The HP-33s is the new version of the HP-32sii calculator. I describe some of the characteristics of the 33s and present four programs (commentary and code) for it: (1) Solving 3x3 and 2x2 linear equations; (2) bit-fiddling (AND, OR, XOR, ...); (3) sorting; and (4) linear least squares. Techniques for addressing the shortage of Labels are also covered.
3. Monte Dalrymple
Title: The NEWT (Nut, Extended, With Turbo) Microprocessor and 41CL Calculator
Synopsis: Contrary to popular myth, moving an obsolete microprocessor to a newer technology isn't that hard and doesn't need to be that expensive. the original nut microprocessor, used in the HP41C, is a prime candicate for this kind of redesign. The NEWT design wraps extra logic around a clone of the Nut microprocessor, adding a parallel memory interface (1Mx16) and higher-speed operation (up to 50x)
while maintaining bus compatibility for the 41C ports. this will allow a replacement CPU board to be implemented and substituted into a HP41C body. This enhanced calculator (A 41CL?) can hold numerous ROM images, a complete MLDL, and operate up to fifty times faster than the original HP-41C
4. Cyrille de Brebisson & Art Garcia of HP
Title: None, Q & A
5. Joseph K. Horn
Title: PDQ Unbound: No More Limitations
Synopsis: PDQ's only two limitations have been removed, namely, the allowable size of the input, and the accuracy of the output, both formerly limited to the computer's number of internal decimal places. Now ANY input is allowed (any number of decimal places, AND a new option: fractions with numerator & denominator of any size), AND the desired precision can be HIGHER than the native ability of the computer, and in fact can be ANY desired precision. For example, using an hp49g+, I can input a 30-digit decimal number, and specify that I want the best fraction that evaluates to the same thing +/- 1 digit in the 26th decimal place. Or 50th decimal place! Or whatever, without limitation. Overhead.
6. Dave Hicks
Title: The Hitchhiker's Guide to the HP Museum
My informal talk will cover: Site inspiration and objective; Peer pressure from total strangers; Implementation and running of the site, The classified ads and forums, Spammers, trolls, and ebay warriors; CDs and DVDs, past, present, future; Website future.
7. Paul Hubbert
Title: Latest Electronics Handheld "Toy" Bargains
Synopsis: Each year the electronics industry packs more technology into ever smaller packages. What was a complex function costing hundreds of dollars is now available from an Asia manufacturer (usually China) for tens of dollars. Add to this the low sales cost of the Internet and there are thousands of bargains to be found - if you have the time and dollars to risk. I will make a short presentation of the results of my search for items related to HP Handhelds and . . . . Imagine a 2.2 GB microdrive delivered for $142, or a 256 MB SD memory for your HP49 for $ 35. Examples on hand.
8. Ted Kerber
Title: Third-Party Applications for the HP49G+
Synopsis: Some suggestions for protecting your application from copying. Also takes a brief look at how applications help sell calculators, from the HP65 to the HP41CV/CX, in comparison to the 48 and 49 series of calculators, solution books, learning aids and teaching aids. Addresses HP support for applications, then and now and how the current tool of “partnering” can help both the manufacturer and the developer.
9. Wlodek Mier-Jedrzejowicz
Title: 10 Things a Calculator Will Never Do
Synopsis: Instead of looking for ever more features a calculator could have, I want to ask what sort of things an electronic handheld calculator will never do. Some of the answers to such a question can help us define what a calculator is, for example a calculator is not a word processor. Other answers will serve as reminders of the limitations that nature puts on the process of calculation. Thirdly, a few of the answers may be seen as challenges to future developers. Audience participation will be very welcome what do you think a calculator cannot do or should not do?

Title: Report on ICME 2004 Conference for Maths Educators in Copenhagen
Synopsis: At HP’s invitation, I presented a workshop at the International Conference of Mathematics Educators in Copenhagen, in July this year. This talk will be an informal description of my experiences at this conference. In particular, I want to compare the ways in which HP, Casio and TI presented themselves and their products to the conference attendees.
11. Richard J. Nelson
Title: Personal Low Cost Book Binding
Synopsis: Many manufacturers like HP provide their equipment manuals on CD ROMs. This means that you must print your own manuals. With a $30 equipment investment and a supplies cost of about 30 cents per book, you may bind up to 320 pages in an attractive "hard bound" style book using this system. Examples of various colors and cover styles will be presented. Books will be "bound" during the talk to illustrate how simple and easy the system works. Demonstration.

Title: Superman Looks at the HP17BII+
Synopsis: Historically users would disassemble their machines and photograph them using macro photography to document new models. Presentations made at HHC projected these 35 mm slides using a long throw zoom lens to provide as much magnification as possible to study new calculator technology. More recent techniques utilized video cameras and monitors for this purpose. Modern X-ray machines provide a high tech noninvasive examination technique suitable for viewing calculators. Machines designed for circuit board inspection provide magnifications of up to 1600x if the parts are small and may be moved very close to the X-ray tube. A Power Point presentation will provide a "tour" of the internals of the new HP17BII+ calculator. Astounding images of the complete machine and of individual components will be presented. Power Point.
13. Erich Reclin
Title: The History and Operation of hpcalc.org
Synopsis: Although the hpcalc.org web site has been visited by millions of people over the last seven years, very little has been shared about either its history or its inner workings. I will explain both my reasons for and the process of starting the site, how it has evolved over the years, and difficulties that have been overcome. I will also give an overview of how the site currently operates, including technical details of the code that runs it.
14. Jake Schwartz
Title: Proper Calculator Keyboards and Attachable Overlays
Synopsis: From the HP-35 in 1972 up to the HP48GX in 1993, we have experienced a consistency in keyboard key placement and a steady increase in calculator user-customizability. However, with the movement of the calculator organization from Corvallis to Singapore to Australia and to San Diego over the past decade, personnel and priorities have changed. This is one user's perspective on the current situation and a personal approach to getting "back on track." Emphasis will be placed on the current HP49G+ and the HP33S calculators.
15. David Shier
Title: Present and Future PDA's
The buzzword for today is "convergence". PDAs, phones, digital cameras and MP3 players are all merging into one. All that's missing for the student is a decent calculator. While the Pocket PCs from HP are now coming from the old Compaq group out of Houston, now is the time for HP to consider a convergence of their industry leading calculators and PDAs. In this presentation we will look at the current incarnations of the PDA. In addition, as someone that has been around HP calculators since the 34c and their PDAs from the first 95LX until their newest iPAQ 6315 phone, David will present his vision for a future calculator/PDA - including thoughts for solving certain keyboard dilemmas.
16. Eric Smith
Title: Update on Microcode Simulation of Early HP Calculators
Simulation of HP calculators may be useful to run older calculator software without porting, for general calculator usage (because most modern computing environments including computers, PDAs, and phones
have woefully inadequate calculators), and for historical interest. Many HP calculator simulators are available, but most of the ones that simulate the pre-1986 calculator models only perform only a user-level simulation, and often produce different results and behavior than the real calculator. Microcode-level simulation can potentially be much more accurate, to the point of reproducing the bugs in the original calculator.
17. Gene Wright
Title: Calculating Contrast
Synopsis: The choice of colors for use on calculator keyboards generates great debate between users and designers. For example, the color scheme of the HP48GX is generally considered less readable than the one used for the HP48SX. Using a formula, the presentation will attempt to quantify the degree of contrast involved in the color choices used on present HP calculators. Recommendations will be made regarding "good" or "not-so-good" combinations used. A recommendation will also be made for HP to consider when choosing future color combinations. Power Point.
