Erm. If it is 'simply the best', how come it doesn't 'measure up to the 41c'? Intrigue 07:28, 29 Sep 2004 (UTC)

message: The HP35, 1972-1975, was the first hand-held scientific calculator. It was replaced by the much cheaper HP25 in early 1975. (There is a useful museum site for these devices, http://www.hpmuseum.org/) The HP35 was expensive at $350, and sales were slow. While the precision was good, the first 35k units had a flaw. For example ln(exp 2.02) returned 2.00 rather than 2.02. HP offered to replace them.
HP calcs are still around, although RPN is no longer the rule. Prices range form $15 to $200. 1970s HPs are collectors items, and a working HP25 with the original leather case and manuals will fetch $250. Thats about twice what it sold for in 1978, the final year of production. In early '75, the introduction year, it was $195 in the US, but quickly dropped to about $150 to match the TI offerings. The chances of an HP25 surviving the dreaded battery leak were slim. The nicad pack had to be replaced every 2yrs, which few owners ever did since the battery packs were $40 in 1975. 
Texas Instruments were HP's only rival in the top end calculators of the 70s. Both used the power hungry led displays, and battery charges only lasted for 1hr. Prices ranged from $120 to many hundreds. Cheap calcs made in Taiwan appeared in the late 1975, but HP and TI kept the high professional end. By 1980 the lcd had arrived meaning two AA batts would last for months. Better and cheaper VLSI chips meant that high end calcs would retail for $20, and run for months on a carbon battery.27.33.244.147 (talk) 23:33, 25 April 2015 (UTC)

If somebody wants to find a particular calculator, they'd Find it. Right? Gwrede (talk) 23:52, 26 December 2023 (UTC)
