Since 2019, this ad-free, no-frills web site for my vintage calculator materials (HP, SHARP, etc.), old HP computers and Misc topics (Computer Chess, Fractals) has been possible thanks to Eric Rechlin's generosity and invaluable help. It features Articles, Programs, Challenges, Pictures, Brochures, Book Reviews & Covers, Raw Scans of vintage materials and more, all free to download. There's now 1,090 files available (thousands of pages) and more will be added periodically. Should you want to comment or ask something, this is the thread to do it. For past Update announcements, see here.

Update #38 highlights: 16 HP-67 programs, 9 Full brochures, 3 Raw Scans, 4 Book Covers, 6 vintage letters, 4 Easter Eggs (for a list of all new files see Latest Additions below.)
- Some minor corrections and changes.
Project HAM is now at 3,551 pages = 88.78% completed. See Introducing Project HAM (Historic Albillo Materials).
If you'd like to help, please include a link to this Main page into your own site and/or ask other related sites to do so, for increased visibility. It won't mean a cent but will do wonders to encourage me to spend the enormous effort required to prepare and upload more materials. Thanks !
