HP Calculator Raw Scans

This Section features scans I've made of assorted documents other than Pictures or Brochures, such as booklets or bulletins. Most are part of my Project HAM, i.e., scans of 40+ year-old vintage documents not authored by me but which were sent to me back then, and due to their perceived rarity (even uniqueness right now) I'm making them available here.

I scanned most paper documents at 300 dpi, resulting in hi-res 2,552 x 3,508 PNG images, which were then converted to multi-page PDF documents with embedded OCR'd texts (e.g.: to allow for copy/paste operations). Some of them also include text pages with my own Notes, providing background info and extra details.


PDF HP Raw Scan - 27 Programas para la HP-34C (Full Scan)

(126 pages, scanned by Fernando del Rey, in Spanish with Notes in English)

This set of 27 programs for the HP-34C was developed by Eugenio E. Ubeda Forte in September, 1980. The truly excellent typewritten documentation for the programs is both very extensive (123 pages, average 4.5 pages per program) and comprehensive. The titles for all 5 categories and 27 programs follow, in both the original Spanish and in English:

Caveat lector: All the documentation is in Spanish. However, as the subject matters are mostly mathematical in nature, it's perfectly possible to follow and run the examples with little difficulty, thus also learning how to use the programs.

PDF HP Raw Scan - A Blackbox Handbook to Synthetic Programming Techniques (Full Scan)

(16 pages, 3.133.875 bytes)

A 16-page booklet by Phill Jury (PPC #5484) which was sent to me by John McGechie (PPC Melbourne Chapter) circa 1980, and which I've discovered recently among my 40+ year-old vintage materials so I thought it would be proper to scan it and upload it to this Section as well. Phill says:

"This book is designed to teach the person who has neither the time nor the inclination to learn how the 41C goes about carrying out various non-standard techniques, but explains in detail (step by step instructions), how to use these techiques."

PDF HP Raw Scan - A Capability Study on the HP-35 Pocket Calculator (Full Scan)

(10 pages, 8,946,653 bytes, scanned by Fernando del Rey)

The HP-35 is a 35-key, pocket-sized scientific and engineering calculator. [...] In terms of general advantages, this unit provides much of the problem-solving power of a desktop scientific calculator, combined with the portability and convenience of the slide rule. Unlike the slide rule, it offers unprecedented accuracy and provides answers in a fraction of the time required for slide rule calculation. This Capability Report will explain and evaluate special features of Hewlett-Packard's HP-35 Pocket Calculators, typical applications with comparison of solution times (*), how the unit operates, advanced technological features and general specifications.

(*) The following problems were selected from engineering notebooks and were given to members of Hewlett-Packard's own engineering staff for solutions. Each engineer was asked to time himself in working each problem in two ways: first, with a pilot model of the HP-35, and second, by conventional slide rule methods. Actual results are shown with comparison times, together with keystrokes for the HP-35 and scratch notes required for arriving at the slide rule solutions.

(12 pages, 2.955.836 bytes)

This arrived as a thick 1977 letter from HP "sent to only a few HP-67 and HP-97 owners", encouraging us to take a very comprehensive survey and then send the completed questionnaire back to them. The large envelope included a one-page letter plus the survey's questionnaire proper, which consisted of 8 pages featuring 36 quite complex and detailed, very specific questions. Oh, and a return envelope as well. Includes Notes.

PDF HP Raw Scan - PPC Club Melbourne Chapter Newsletter October 1980 (Full Scan)

A complete 10-page newsletter published by the Australian PPC Club Melbourne Chapter, sent by John McGechie back in October 1980. If you zoom on the quite-faded thermal-paper label you'll see it's addressed to yours truly, and you'll also find me mentioned in page 3 of the newsletter (page 5 of the PDF), I quote:

"A long and fascinating letter from Valentin Albillo had arrived a few days before the meeting, reporting on his latest incredible work (see Overseas News), producing delighted cheers, especially when it was observed that he was one of the two or three overseas members of our Melbourne Chapter. (We are prepared to take all credit, of course...)"

PDF HP Raw Scan - Prof Computing V1N1 1984 - HP-71B A Fistful of Power (Full Scan)

The HP-71B is a brand new machine with computing power far beyond most microcomputers and scientific calculators found on the market today.

At first blush, Hewlett-Packard’s pocket-size HP 71B looks like a cross between the HP Series 41 calculators and a stripped down HP 75 portable. It's not. The 71B is a brand new machine with computing capability far beyond most microcomputers and scientific calculators. And for the first time with a small computer, HP has made available the Internal Design Specifications (IDS) with source code and schematics. While one can't actually call the 71B a pocket IBM 370, it’s close.

PDF HP Raw Scan - Prof Computing V1N4 1984 - HP-71B Proud Parent in Corvallis (Full Scan)

Janet Placido is a proud parent. [...] But Placido’s newborn is not just any kid. It gestated for five years, talks in BASIC and does 6 x 6 matrix inversions in 2.5 seconds. [...] Its given name is HP-71B, but the beaming parents nicknamed it Titan.

The birth of the 71B was a joyous event, especially for Placido, who was a driving force in the design of its operating system. At 32, this dynamic, straight-talking computer scientist is already a project manager, who supervised a team of software engineers devoted to making the 71B the most powerful, most adaptable, most user-friendly handheld ever created.

PDF Introducing Project HAM (Historic Albillo Materials)

This PDF document describes Project HAM (Historic Albillo Materials).

Since June 2021, I'm scanning most of my 40+ year-old still surviving vintage materials. My goal is to upload most everything I've kept stored since then, for interested people to download, read, and get an idea of that Golden Age.

My surviving vintage materials consist of some 4,000 pages, most of which I've scanned at 300 dpi, and have been kindly and expertly postprocessed by Eric Rechlin himself, then collected into multi-page PDF documents, which also include OCR'd text of variable quality. Additionally, some of them also contain a text file with my very own Notes detailing the document's background and interesting trivia.

The selected scanned vintage materials (which I'll upload on a regular basis) include, among others: [... read the full details in this PDF document ...]
