This actually hinders use especially for casual users, as they must switch to a different “mode” of using the device when they program it compared to a more keyboard programmable macro capture mode. The keyboard can be used to some extent, in a sort of “watch me” mode, but most of the programming is done simply with the alpha numeric keyboard option, typing in control flow commands, etc. Most modern programmable calculators are programmed much like the old BASIC hand held computers in the past, using some higher level language. They were effectively elaborate macro systems. The HP-15C was “keyboard programmable”, which basically means that programming was a matter of capturing keystrokes. But what’s most curious is that save for the higher end, expensive, “graphing” models, almost no modern calculators support programming. They have immense capability, packing large functionality in to small spaces, that are dirt cheap (< $15). If you go to an office store today, modern calculators are a marvel. This capability departs in the later, more powerful HP calculators where most of the functions were buried beneath large menu trees, or needing to be keyed in via the alpha keyboard, and the devices themselves revert back to the conventional, vertical layout the dominates calculator design. It is pocket handy, light, thing, and yet used easily with two hands. It managed to combine its high end capabilities like matrix math and integration with a simple, single key access idiom.Ĭombining this utility with the particularly excellent ergonomics of the size, shape, and layout, and key quality is what makes the 15C a treasured tool even today. The HP-15C was a marvel of the day in terms of the balance of functionality and usability. I love the attention to detail HP has put into these applications, and I’m sure many geeks with fond memories of these calculators will appreciate that HP is making them available software-wise. The Windows versions work with the touchscreen PCs HP puts out, making it all a little bit more realistic. ![]() Since these software variants are a lot cheaper to make, this is a clever move by HP. It is important to note, though, that “real” versions of these calculators are a lot more expensive (some still get made). They’re not exactly what you’d call cheap the 12c comes in at USD 14.99, while the 15c goes for USD 29.99. The iPhone gets the 12c financial calculator and the 15c scientific calculator, while Windows gets the HP 35s scientific calculator, the 12c Platinum financial calculator, and the 20b business-consultant calculator. HP has made available a few of its Reverse Polish Notation calculators for the iPhone and Windows. I’m personally not particularly versed in the world of mathematics (other than statistics), but I do know the love many geeks have for their calculators.Īs said, this is a world not travelled for me, so please bear with me, and feel free to give me a proper beating if I get anything wrong. I did find something interesting, though: HP has made several of its classic calculator models available as iPhone applications or as Windows applications. Users also have the option to redefine the number of certain keyboard keys.I guess the tragic death of Michael Jackson put the internet on hold or something, as the amount of news we can find has come to a grinding halt. This allows for label addressing (0-9 and A-E), subroutines (nestable to 4 deep), 8 conditional tests, increment/decrement loops, and 2 flags. ![]() The main advantage of the 11C calculator is its programming capabilities. Other built-in features of the HP 11C calculator include hyperbolic and inverse hyperbolic trigonometric functions, combinations and permutations on probability, percent change, factorial, and absolute value. These two features are its built-in random number generator and a backspace key that enables users to correct a problem or formula one number at a time. modes (degrees, radians, grads) 3Ī mid-range and programmable scientific calculator, the HP 11C has two features that are an improvement from an earlier version, the 33E/C.
