HP Calculators
HP calculators are various calculators manufactured by the Hewlett-Packard company over the years. Their desktop models included the HP 9800 series, while their handheld models started with the HP-35. Their focus has been on high-end scientific, engineering and complex financial uses. History In the 1960s, Hewlett-Packard was becoming a diversified electronics company with product lines in electronic test equipment, scientific instrumentation, and medical electronics, and was just beginning its entry into computers. The corporation recognized two opportunities: it might be possible to automate the instrumentation that HP was producing, and HP's customer base were likely to buy a product that could replace the slide rules and adding machines that were being used for computation. With this in mind, HP built the HP 9100 desktop scientific calculator. This was a full-featured calculator that included not only standard "adding machine" functions but also powerful capabilities to ...

HP48G
The HP 48 is a series of graphing calculators designed and produced by Hewlett-Packard from 1990 until 2003. The series includes the HP 48S, HP 48SX, HP 48G, HP 48GX, and HP 48G+, the G models being expanded and improved versions of the S models. The models with an X suffix are expandable via special RAM (memory expansion) and ROM (software application) cards. In particular, the GX models have more onboard memory than the G models. The G+ models have more onboard memory only. The SX and S models have the same amount of onboard memory. Note that the similarly named hp 48gII (2004) is not a member of the series but closely related to the HP 49G+. The calculators use Reverse Polish Notation (RPN) and the RPL programming language. 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.

HP-IL
The HP-IL (''Hewlett-Packard Interface Loop''), was a short-range interconnection bus or network introduced by Hewlett-Packard in the early 1980s. It enabled many devices such as printers, plotters, displays, storage devices (floppy disk drives and tape drives), test equipment, etc. to be connected to programmable calculators such as the HP-41C, HP-71B and HP-75C/D, the 80-series and HP-110 computers, as well as generic ISA bus based PCs. Principles As its name implies, an HP-IL network formed a loop (i.e. it was a Ring network): each device in the loop had a pair of two-wire connections, one designated ''in'', which received messages from the previous device in the loop; and one designated ''out'', which delivered messages to the next device in the loop. One device on the loop is designated the ''controller'', and manages all other devices on the loop. HP-IL cables utilize a unique two-pin connector design with polarizing "D"-shaped shells, and can be connected together ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HP-16C
The HP-16C Computer Scientist is a programmable pocket calculator that was produced by Hewlett-Packard between 1982 and 1989. It was specifically designed for use by computer programmers, to assist in debugging. It is a member of the HP Voyager series of programmable calculators. It was the only programmer's calculator ever produced by HP, though many later HP calculators have incorporated most of the 16C's functions. Features The 16C can display integers in hexadecimal, decimal, octal and binary, and convert numbers from one number base to another. It also deals with floating-point decimal numbers. To accommodate long integers, the display can be 'windowed' by shifting it left and right. For consistency with the computer the programmer is working with, the word size can be set to different values from 1 to 64 bits. Binary-arithmetic operations can be performed as unsigned, one's complement, or two's complement operations. This allows the calculator to emulate the programmer's co ...

HP-15C
The HP-15C is a high-end scientific programmable calculator of Hewlett-Packard's Voyager series produced between 1982 and 1989. Models HP-15C The HP-15C is a high-end scientific pocket calculator with a root-solver and numerical integration. A member of Hewlett-Packard Voyager series of programmable calculators, it was produced between 1982 and 1989. The calculator is able to handle complex numbers and matrix operations. Although out of production, its popularity has led to high prices on the used market. The HP-15C was a replacement for the HP-34C. The 15C used CMOS technology for its processor, resulting in very low power consumption. HP 15c Limited Edition After showing a prototype labelled "''HP 15c+''" at the HHC 2010, HP announced the ''HP 15c Limited Edition'' (NW250AA) on 1 September 2011. It is based on a flashable controller utilizing the same ARM7TDMI core already used in the 2008 revision of the 12C but in a different package, an Atmel AT91SAM7 ...

HP-12C
The HP-12C is a financial calculator made by Hewlett-Packard (HP) and its successor HP Inc. as part of the HP Voyager series. Functionality The HP-12C is HP's longest and best-selling product, in continual production since its introduction in 1981. Due to its simple operation for key financial calculations, the calculator long ago became the ''de facto'' standard among financial professionals. Its popularity has endured despite a relatively simple but iterative process such as amortizing the interest over the life of a loan, a calculation that modern spreadsheets can complete almost instantly, can take over a minute with the HP-12C. The 1977 October edition of the ''HP Journal'' contains an article by Roy Martin, the inventor of the simple method of operation used in HP financial calculators, which describes, in detail, the mathematics and functionality built by William Kahan and Roy Martin that is still used today.

HP-10B
The HP-10B (F1636A) is a student business calculator introduced in 1987. The model of this calculator proved to compete well with the higher end RPN HP-12C. Two versions of the 10B were produced, the first version came with orange lettering around the keys and used an 1LU7 HP Saturn processor, the later model (in 2000) with teal-green labels. The functionality of the two versions appears to be identical. The successor HP 10bII (F1902A), which was introduced in 2001, is essentially a cosmetic upgrade offering the same overall functionality, but actually reduces the available numbered-storage registers from 15 to 10. Early production runs were of poor quality; newer calculators have apparently solved this shortcoming. In 2011, the 10bII was replaced by the HP 10bII+ (NW239AA) model 1 (codenamed "Bluestar") with expanded capabilities. This model also allows chain input. The 10bII+ uses a flashable Atmel AT91SAM7L128 processor with ARM7TDMI core. In 2015, the internal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
