| | In any case, the HP-75C was closely related to HP handheld calculators, and led directly to the HP-71B which was a smaller handheld computer, but with a calculator mode. | | | Apart from HP's usual reluctance to advertise, further reasons for the low sales may be that the target market was not aware of HP calculators, and that the tiny printer was reputed to be unreliable. | | | These secondary registers were used by the statistics functions, avoiding the problem common on HP calculators that statistics operations destroy data in some of the numbered registers. |

| | HPCC : HP-41C/CV/CX |
| | HP also ensured that the HP41 remained competitive against newer more mathematically powerful calculators by bringing out the Advantage Module which added some of the financial functions of the HP-12C, complex number and matrix handling like those on the HP-15C and computer science funtions like those of the HP-16C. | | | Described in one HP brochure as "Unsurpassed in terms of software, expandability and versatility, these are the calculators that grow with your needs." The HP41 series of calculators were considered by many people to be the ultimate calculator. | | | HP's first attempt at correcting this problem was the Quad memory module which allowed full expansion of user memory whilst using only 1 slot. |

| | The new models, however, reportedly didn't have the mechanical quality and sober design HP's earlier calculators were famous for (instead featuring the more "youthful" look and feel of contemporary competing designs from TI). | | | In March 2002, HP announced that the company would no longer produce calculators, which was hard to fathom for some fans of the company's products; the HP-48 range in particular had an extremely loyal customer base. | | | It could be expanded with RAM (memory) and ROM (software) modules, as well as peripherals like bar code wands, cassette tape and floppy disk drives, paper-roll printers, and miscellaneous communication interfaces ( RS-232, HP-IL, HP-IB). |

| | HP Network - Interview : Eric Rechlin |
| | It's truly a sad thing to see happen, since RPN is so much more efficient than algebraic input, but if RPN calculators stop being produced (which will happen if/when HP halts calculator production), there is no hope. | | | At my university, which has an excellent engineering program, I still don't see many HP calculators. | | | I wouldn't even know where to begin to mention the HP programs which most impress me. I suppose the obvious responses would be MetaKernel, Java, Jazz, Erable, and ALG48, but there are many other smaller programs out there that deserve mentioning as well. |

| | The future of HP calculators |
| | Since the narrow bus requirement no longer exists, it is reasonable to expect that HP will switch to a new processor architecture for future calculators. | | | HP has flirted in recent years with non-RPN calculators such as the 17B and 19B, but I must surmise that they realized that they had alienated loyal customers since they added RPN capabilites back in with the 17BII and 19BII. | | | I am personally not the least bit opposed to HP making efforts to increase the accessibility of future high-end HP calculators to the masses by making more capabilities usable with algebraic entry, as long as they don't forget their loyal customer base who want RPN. |

| | Likewise, the hardware and software design of the HP-48 calculators are themselves strongly influenced by other calculators in the HP line, most of all by the HP-18 and HP-28 series. | | | The HP-48 is a series of graphing calculators using Reverse Polish notation (RPN) and Reverse Polish Lisp (RPL), produced by Hewlett-Packard (HP) from 1990 until 2003. | | | The hardware architecture developed for the HP-48 series became the basis for the HP-38G, with a simplified user interface and an infix input method, and the HP-49G with various software enhancements. |

| | ...I lost a friend |
| | With RPN, and the finer knowledge and understanding of Order of Operations that came with using it, problems on the Calculator Applications test can be done completely without parenthesis, a task that is frustrating at best trying it with TI (or Casio or Sharp, or even with HP Algebraic Entry calculators) frustrating at best. | | | I tend to read the articles on the HP forum at www.hpmuseum.org, a website for classic HP calculators (which I have loved since I first got my hands on an HP-11C in 89) and found this article. | | | And of course, the graphing calculators (the reason HP ran the 32SII out) aren't even allowed on the mathematics or science test, so the future of UIL math and science events is blurry at best. |

| | Programmable Calculators: Hewlett-Packard HP-48G |
| | For the HP-28/48 series of calculators, I have already presented a complex implementation of this function, and an implementation of the incomplete Gamma function as well. | | | The HP-48G is the "low-end" (is this term really appropriate for a machine with graphics, symbolic math, infrared and RS-232 I/O, and more features than you can imagine?) member of a series of Hewlett-Packard calculators that replaced the highly successful HP-48SX line. | | | Just as keystroke programmable calculators were a perfect learning tool for the programmer of the 70s or the early 80s, this machine with its object-oriented User RPL language is the perfect learning tool for the 90s and beyond. |

| | TI Graphing Calculator FAQ: TI-89 family vs. HP 49g+ |
| | HP sold graphing calculators to engineers back when the high cost of such a device made it not worth it to anybody else, so the presence of a variety of functions most would find obscure isn't surprising, while still getting the job done when it comes to the more mundane, everyday things. | | | While the HP used to have great software written in hand optimized in asm, and the TI's used is written in C, the emulation layer destroys most of the advantage. | | | - The HP is 2-6 times as fast for complex numerical computations. |
