HP collection
I have a large collection of Hewlett Packard calculators. It all started in 1989 when I bought my first HP-28S whilst I was studying engineering at University.
I inherited my grandfather's slide rule collection in 2000 and made the link to the HP-35 (which revolutionised everything and made the slide rule obsolete). I bought one as I knew my grandfather would have loved one, then had to have most of the other models that followed.
I have over 200 HP's in my collection now - including some very rare prototypes, clear cases and rare items.
The largest subset of my HP collection is the 12C - I have about 30 of these - I have a separate set that covers the 12C. Enjoy!
