HP Personal Calculator Digest Volume 5

[PedroLeiva]

Good morning to all. I thank Robert Prosperi very much for the clarifications he made to the Forum. I want to explain the reason of my request. In the following publication about forestry https://environment.yale.edu/gregoire/do...o10_81.pdf , the bibliography textual quotation is: Froley, M. (ed.). 1979. HP-67/97 programs. The Hewlett-Packard Personal Calculator Digest 5: 9.

I thought it described some calculation program, but it was simply a catalog, which has nothing to do with a reference to the cited paper, it is also badly done in relation to the number and location of the pages. However you will wonder how I obtained the cover of the magazine, because on the web I found this excerpt http://www.decadecounter.com/readingroom...u_beep.pdf . Someone extracted an article from the magazine and added the cover, unfortunately without the table of content index that would have allowed me to know it was not what I was looking for. This corresponds to what Uli uploaded to the Forum.

I thank the people who sent me the PDF with the contents of HP-67/97 of the magazine. I congratulate Didier Lachieze for discovering that the theme that motivated the original author citation is HP67 Forestry Application Pac, which describes the programs of forest cubing and calculation of wood production. This compilation interests me a lot, maybe I will ask Dave Hicks to sell it to me from his collection. The original HP67 program, by the authors Rockwood & Riman (1981) of 188 steps (from the link in the first paragraph), will be very difficult to find after 38 years.
