Re: Your choice of calculator at work Message #32 Posted by Mike Morrow on 3 Sept 2009, 1:36 p.m., in response to message #1 by hecube
The HP calculator that I used most productively in my work at the time (nuclear submarine officer) was the HP-67, in 1977-79. (It and accessories cost me more than a month's salary.) Later, I spent a lot of quality time with an HP-41C in civil work.
More than 20 years ago, I settled on regular use of an RPL and an RPN scientific, plus a financial calculator. Subsequently, the RPL machines were HP28C, 28S, 48SX, 48GX, and 49G+. The RPN machines were HP-41C, 41CX, 15C. The financial machine was the HP-12C.
Today, I use the HP50g and HP42S, plus the HP17bii for financial calculations.
The RPN units are (to me) much easier for programming simple problems, compared to the RPL units, hence the two scientifics. Plus, though the HP50g has some financial calc support, what comes built-in doesn't closely match the HP17bii.
My dream machine would be an HP50g that could *also* be programmed in RPN, and that had all the functions of the HP17bii built-in. Then I'd have just one HP in the briefcase.
