HP celebrates 35th anniversary of HP-35: launches 35s calculator

Feel that? That's the unexpected stir of nostalgia welling inside your dorktic-loin. Rest easy, you're not alone. In fact, that picture aroused a deeply seeded HP fanboi-ism long obscured by thick slabs of drab computing plastic and opaque printer ink. The 35s marks the 35th anniversary of the industry defining HP-35 pocket scientific calculator (and death of the sliderule) -- a first to offer basic trig and exponential functions. While HP preserved the original's reverse Polish notation, gone is the single-line of red LEDs which illuminated the childhood wonder of so many budding engineers. The new 35s also introduces an algebraic entry mode for those who find RPN entry just a bit too, well, reversed. Of course, it's fully modern with 800 storage registers, 100 built-in functions, and a large 2-line alpha numeric display with adjustable contrast. Better yet, the 35s will only set you back $60 compared to the $395 it cost back in 1972 -- that's a lot more 8-tracks for your swank Ford Mercury Capri, eh Pops?
