As useful today as it was in 1981
1 of 1 found this helpful I consider this the epitome of engineering calculators because it has all the features I've ever needed (as an electronic design engineer) and it's very convenient to use. The batteries last for several years, never loses its storage, it's programmable, has RPN and doesn't complicate things with unneeded bells and whistles. Though it's no longer made by HP, it's readily available used. There is even a small company, swissmicros.com, which makes a clone but I go for the used originals for about the same price.
