Vicinno 15C scientific calculator is the most accurate and precise emulator of the world-renowned HP 15C RPN high-end scientific. However, for now, is be grateful if they would just ensure their existing emulators are compatible with future iOS versions. The New 15C is simulator of 15c Scientific Calculator with below functions. We use the identical mathematics and calculations with the original to deliver exactly same capabilities and excellent performance. ![]() pocket calculators of the 80s, most notably the HP 12C and HP 15C models. 15C Scientific Calculator 4+ Vicinno Soft LLC 4.5 71 Ratings 14.99 Screenshots 15C scientific calculator is the most accurate emulator of HP 15C RPN high-end scientific programmable calculator. I think HP would have a profitable business unit if they took seriously bringing these great little computing machines back to life in the whole family of reasonably priced emulators. My RPN calculator is a scientific and financial calculator inspired by the. Other developers are keeping up with their HP emulators, some of which are very nice. Apple says they are not compatible with future versions of iOS. HP needs to update the 12 and 15 soon though. Phone size is about the actual size of the real machines too. However, The emulators for the iPhone are so nice to have and I use them regularly, and they're all in my pocket on the iPhone 6s+. I prefer to use the real ones only occasionally now, because there are no more replacement parts. No other calculator type, has ever surpassed the HP family. I've used HP calculators most of my life, since my first HP67 in 1980. They are probably the most usual kind of transistor now in use and have been that for a long time.We need an iOS compatible upgrades from HP soon!! Vicinno 15C scientific calculator is the most accurate and precise emulator of the world-renowned HP 15C RPN high-end scientific programmable calculator. The secret is that the integrated circuit, or chip, in this calculator was made using a silicon-on-sapphire technique, where the usual silicon, before etching the electronics on it, is first deposited on top of a sapphire layer, where it bonds to it so the sapphire then provides a very strong insulation to all the electronic components, so much less of the batteries charge is wasted in leakages from them:Īs to what are the MOS or MOSFET transistors? Here is an explanation for the technically minded. So I first looked for orientation in old and trusty Wikipedia, and found the whole story there, as well as an explanation of the amazing long-life of the tiny batteries it uses: For that I wrote a program to find out and used my trusty old calculator for doing much of the checking of the results.Īs I was doing that I had this thought: “Listen Oscar, you have been using this thing for over thirty years and have not changed its batteries for at least 15, maybe 20 years. Case in point: just now I have been imagining a mission with a very little and cheap (in terms of “normal” space prices, that is) kind of satellites that are all the rage now days, known as “cubesats” because of their usual shape, with several deployed in each of a number of equally spaced orbit planes, so I needed to figure out, among other things, how many of those planes would be enough to do the intended job and how long it will take to deploy the little satellites until all the planes are occupied and in the desired configuration. I often use it to check results when running tests on the software I need to write, for example to figure out if certain ideas of mine, or of someone else, are feasible or not in practice. Having always had access to regular computers, I have had little use for these functions, except for the direct and inverse trig functions, logarithms, exponentials and roots. This particular calculator, one of a series of models, was produced by HP from 1982 through 1989, can be used to write in it and then save for their later use, subroutines involving numerical integration, matrix multiplication and inversion, trig functions (direct and inverse), logarithms, rise numbers to powers and, or find their square roots and to do other usual operations in engineering R&D and for scientific number crunching. FWIW I have killed other HP calculators along with TIs at a rate of about 1 every 5 years, Im a little. I am the owner, as I had long suspected, but only found out for sure very recently, of a most remarkable little hand calculator I bought back in the mid-eighties: a programmable Scientific Calculator HP 15C. This price is enough to temp me into buying a new one.
