Valentin Albillo's HP Collection
Welcome to my new site and Happy New Year 2020. Latest update #12 was uploaded Feb,5th (5 new files)
At long last, and thanks to Eric Rechlin's incredible generosity and invaluable help, I finally have this web site for my calc-related materials (HP, SHARP and other brands, as well as assorted vintage HP computers and other Misc topics) to be permanently online again, including Articles, Challenges, Programs, Pictures, Book Reviews, Selected Threads and more, all freely available for interested people to download and hopefully enjoy. Right now there are some 435 files available and I intend to eventually upload new materials iff I see enough interest, real-life chores permitting of course.
