This Section features scans I've made of selected letters I exchanged with a number of HP-calc fans mainly from 1979 to 1981 and a few beyond. All are part of my Project HAM and due to their perceived historic worthiness I'm making them available here for the very first time.
I scanned most letters 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 when possible (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.
Various letters sent by the Hewlett-Packard Users' Club Europe to Fernando del Rey when he asked for info about the club in order to subscribe to it (I got the same letters, these are his).
It includes one typical envelope, Member Rules and Regulations, Program Orders and Program Submittals conditions, Payment conditions, announcing the first & second European Updates to the Users Library Catalogue, announcing a questionnaire and the latest Key Notes edition V2N1, the April 78 Catalogue Update (547 new programs), the Users' Club BLUE and GOLD MEMBER CARDS, the European Users' Library becoming multilingual and offering recorded magnetic cards, a Membership Renewal Notice and a Thanks Note for renewing, three different models of Program Order Form-Invoice sheets, and a Shipping Label Form.
Hopefully this will allow today's users to get an idea of just how dynamic and exciting was to own an HP-67, HP-97 or HP-41C calculator back then, and how deeply was HP committed to their advanced calculators and users.
I had subscribed earlier to the HP UPLE (HP Users' Programs Library Europe) but once it expired I failed to renew my subscription and HP Europe promptly sent me a letter (which regrettably seems to be lost) asking me for the reasons I had not to renew.
The present letter is my reply to them [...] Includes Notes.

This is the very first letter I wrote back in 1979 to John McGechie (Australian PPC Melbourne Chapter) when I was a very young adult and still at High School.
At the time, I was but a fledgling HP-calc user with rudimentary self-taught English, but already bitten to the core by the HP bug. Includes Notes
This is the very first letter I sent to PPC back in 1979 asking to join the Club [...] I was
absolutely ecstatic at discovering PPC CJ and wanted to be a part of it ASAP, thus this enthusiastic letter [...]
This is how it all began. Includes Notes.

This was John McGechie's handwritten 6-page reply to my very first letter to him, where I unashamedly asked him zillions of questions, as an interested but total newcomer to the 1979 HP calc scene was bound to do.
He answered most of them and encouraged me to join PPC for further tons of information, which I promply did. Includes Notes
This is PPC's reply to my 1979-12-10 letter asking to join the Club, once I sent the required money for a one-year subscription. PPC duly processed it and I was assigned PPC Member Number #4747, a nice number which I very much liked.
My initial subscription ran from January 1980 to December 1980, and it was renewed exactly once. While it lasted I [...] Includes Notes.
This is my first letter to William C. Wickes, of 41 Synthetics (and later RPL) fame, sent just after I joined PPC (Jan 1980), thus becoming Member #4747.
At the time I was very keen in contacting relevant people mentioned there, to try and get hold of all the marvels I saw announced in the pages of PPC CJ, such as [...] Includes Notes.
This is my reply to Michael Tarnowski, who back in 1980 wrote a letter to me (alas, probably lost) with a number of questions about my program "52206 A Chess Game" for the HP-67, which I had earlier submitted to the HP Users' Program Library Europe. Includes Notes.
This is Michael Tarnowski's (Germany) reply to my letter dated 1980-02-01, in which I
explained in detail the internal logic my "52206 A Chess Game" HP-67 program used to make its moves and win the game.
As seen in my next letter to him, dated 1980-04-01, I did my best to comply with his requests and actually much more. Includes Notes.
This is my second letter to Michael Tarnowski, who formerly was interested in the logic used by my program "52206 A Chess Game" for the HP-67 (submitted by me to the HP Users' Program Library Europe), so I sent him a first letter providing the information he asked for, [...]
Additionally, I took the opportunity to inform Mr. Tarnowski about PPC, including a very detailed primer on HP-41C synthetics and their uses, and attaching to my letter photocopies of a number of relevant articles about synthetics. I also included a list with 160 UPLE HP-67 programs I owned [...]. Includes Notes.
This letter was sent to me by D. Felipe Landa in reply to a letter I previously sent him (now sadly lost) after I saw his name in the UPLE Catalog as the author of a number of quite interesting programs submitted by him to the HP UPLE (Hewlett-Packard's Users' Program Library Europe), to which I was subscribed at the time and had also submitted many programs as well. Includes Notes in English.
This is my reply to a letter sent by D. Felipe Landa a week earlier (see 1980-06-07 - Carta de Felipe Landa a Valentin Albillo.pdf), in which he kindly offered to directly send me any number of his HP-67 programs submitted by him to the HP UPLE, and also commenting that in time he got quite disillusioned when ordering UPLE programs with highly suggestive titles and abstracts but ultimately very disappointing. Includes Notes in English.
This 7-page letter is one of the first I sent to Richard Nelson, who was in charge of PPC back then. I wrote many others once my PPC subscription started for good in January 1980 (about one letter per month, sometimes two) but this is the earliest survivor [...] and included 6 pages with my newest contributions to the ongoing PPC ROM Project and other PPC Journal regular sections, namely:
This 5-page letter is also one of the first I sent to Richard Nelson, who was in charge of PPC back then. In this letter I focused mainly on various aspects of the PPC ROM Project logistics. I also included a couple of additional contributions for the ROM, namely:
This is my 3-page second letter to John McGechie, of the Australian PPC Melbourne Chapter, who previously had most kindly replied to my first batch of a zillion questions in a very comprehensive, handwritten multi-page letter where he strived to answer them all as best he could.
After a several-month hiatus and having joined PPC as he suggested in his reply, I took the opportunity to contact him again and show him my progression from "utterly clueless newbie" to "accomplished knowledgeable member" (or something like that), though that wouldn't save him from still more questions and some private comments.
Among the matters I discuss in this second letter, there's a report on my attempt to create a CP (Clear All Programs) synthetics-based routine for the PPC ROM, which features my tentative code, [...]. Includes Notes.
This 26-page (!) handwritten letter is Melbourne PPC Chapter's John McGechie's reply to my previous letter to him dated 1980-07-15. John's handwriting takes some effort to decipher at times, but it's totally worth it.
He begins with some very detailed comments (several pages in fact !) about my attempt to create a CP (Clear all Programs) synthetics-based routine for the PPC ROM, including a number of suggestions on how to successfully implement it using his own b2 routine. He then discusses in great detail the various types of END and .END., and his attempts to create a RAM test to check their locally-created double-density RAM modules. Includes Notes.
This 6-page letter is my reply to the 26-page handwritten letter that Melbourne PPC Chapter's John McGechie sent to me dated 1980-08-05. [...] I expressed my appreciation for his comments and suggestions about my CP (Clear all Programs) synthetic routine, and my intention to experiment with the .END. to make it work.
I also included a short but detailed analysis of CP, explaining what it did and how, and much more, such as synthetic trivia, numeric built-in functions which can return alpha data (!), my own sleuthing re "ghost" functions, useful tips and hints, the works ! Includes Notes.
