Just another day at the HP OfficeCalc 300

HP, which sort of got its start making calculators, is still churning out new models. I find this particular new one, the HP OfficeCalc 300, moderately beautiful, if only for its physical switches and built-in "Check & Correct" memory buttons. (I would pretend the "Correct" button is a way to encourage the calculator for its good performance.) HP's 2009 calculators [HP.com]

    Like HP’s PC’s HP’s calculators are no longer designed in-house. while PC’s are OEM/ODMed by folks like foxconn and wistron, the calculators are now designed/manufactured by kinpo electronics.

    there’s a great article on hp’s shutdown of their calculator operations here:

    It can’t possibly be a real HP calculator – it has an “=” key :^P RPN forever!

    Um, HP got it’s start building Audio Oscillators in 1939, and built precision test equipment for decades. While they did introduce the first scientific pocket calculator the HP-35 in 1972, 33 years after it’s founding.

    Sort of like saying IBM got it’s start building laptops.

    IIRC, IBM, the former International Business Machines Corporation did get its start making calculators.

    @Monopole: I stand corrected!


    I still use my vacuum tube 1950s era H-P 200CD sig gen. It works perfectly and has lower distortion than the modern solid state ones that I’ve had.
    My last H-P calculator lasted 10 years, which was a good run, but nothing like the 200CD’s half century.
