HP Xpander
The HP Xpander (F1903A) aka "Endeavour" was to be Hewlett-Packard's newest graphing calculator in 2002, but the project was cancelled in November 2001 months before it was scheduled to go into production. It had both a keyboard and a pen-based interface, measured 162.6 mm by 88.9 mm by 22.9 mm, with a large grayscale screen, and ran on two rechargeable AA batteries. It had a semi-translucent green cover on a gray case and an expansion slot. The underlying operating system was Windows CE 3.0. It had 8 MB RAM, 16 MB ROM, a geometry application, a 240×320 display, a Hitachi SH3 processor, and e-lessons. One of the obvious omissions in the Xpander was the lack of a computer algebra system (CAS). Math Xpander After discontinuing the Xpander, HP decided to release the Xpander software, named the ''Math Xpander'', as a free-of-charge application that ran on Windows CE-based Pocket PC devices. It was hosted by Saltire Software, who had been involved in its de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windows CE
Windows Embedded Compact, formerly Windows Embedded CE, Windows Powered and Windows CE, is an operating system subfamily developed by Microsoft as part of its Windows Embedded family of products. Unlike Windows Embedded Standard, which is based on Windows NT, Windows Embedded Compact uses a different hybrid kernel. Microsoft licenses it to original equipment manufacturers (OEMs), who can modify and create their own user interfaces and experiences, with Windows Embedded Compact providing the technical foundation to do so. The current version of Windows Embedded Compact supports x86 and ARM processors with board support package (BSP) directly. The MIPS and SHx architectures had support prior to version 7.0. 7.0 still works on MIPSII architecture. Originally, Windows CE was designed for minimalistic and small computers. However CE had its own kernel whereas those such as Windows XP Embedded are based on NT. Windows CE was a modular/componentized operating system that served as ...

Graphing Calculators
A graphing calculator (also graphics calculator or graphic display calculator) is a handheld computer that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. Most popular graphing calculators are programmable calculators, allowing the user to create customized programs, typically for scientific, engineering or education applications. They have large screens that display several lines of text and calculations. History An early graphing calculator was designed in 1921 by electrical engineer Edith Clarke. The calculator was used to solve problems with electrical power line transmission. Casio produced the first commercially available graphing calculator in 1985. Sharp produced its first graphing calculator in 1986. Hewlett Packard followed in 1988. Texas Instruments in 1990. Features Computer algebra systems Some graphing calculators have a computer algebra system (CAS), which means that they are capable of producing ...

HP Jornada X25
The Jornada was a line of personal digital assistants or PDAs manufactured by Hewlett-Packard. The Jornada was a broad product line that included Palm-Size PCs, Handheld PCs, and Pocket PCs. The first model was the 820, released in 1998, and the last was the 928 model in 2002 when Compaq and HP merged. The Jornada line was then succeeded by the more popular iPAQ model PDAs. All Jornada models ran Microsoft Operating Systems that were based on Windows CE. Model variations Handheld PCs Jornada 820/820e It ran on the Windows CE 2.11 operating system, Handheld PC Professional Edition 3.0, had a small trackpad with two buttons and a built-in miniature keyboard. It had 16 MB of RAM, 16 MB of ROM, Intel StrongARM CPU at 190 MHz, 640x480 256 color screen, 1 CF Type II, 1 PC card. It had a 10-hour battery life, and allowed for sending and receiving of faxes through its built-in modem. There is a software update to Handheld PC Professional Edition 3.01/Service Pack 1, and a 16 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TI PLT SHH1
TI PLT SHH1 (Personal Learning Tool, Spot Hand Held) is a prototype calculator created by Texas Instruments as an early attempt to develop a Linux-based calculator. It features an ARM based OMAP 1510 processor, 16 MB RAM, and an SD slot. In conjunction with its ''TI PLT-FHH1'' Personal Learning Tool, Fido Hand Held and ''TI PLT-SU1'' Personal Learning Tool, second generation are prototype calculators. The project was eventually scrapped by TI in early 2004. However, a few of the early prototypes such as the PLT SHH1 leaked to the public, making it one of a few rare prototypes among collectors. A few elements of its design, including its large screen and casing, seem to have been reappropriated for use in the TI-Nspire. PLT-FHH1 Personal Learning Tool, Fido Hand Held · PLT-WS1 Personal Learning Tool, Wireless Sled (PET project was canceled) Similar products *TI-Nspire The TI-Nspire is a graphing calculator made by Texas Instruments, which was released in July 2007, ...

Casio ClassPad 300
The Casio ClassPad 300, ClassPad 330 and fx-CP400 are stylus based touch-screen graphing calculators. It comes with a collection of applications that support self-study, like 3D Graph, Geometry, eActivity, Spreadsheet, etc. A large 160x240 pixel LCD touch screen enables stylus-based operation. It resembles Casio's earlier Pocket Viewer line. HP and Texas Instruments attempted to release similar pen based calculators (the HP Xpander andPET Project(see TI PLT SHH1), but both were cancelled before release to the market. The ClassPad 300 allows input of expressions, and displays them as they appear in a textbook. Factorization of expressions, calculation of limit values of functions, and other operations can be performed while viewing the results on a large LCD screen. It also comes with graphing tools for 3D graphing and drawing of geometric figures. The user interface features a pull-down menu format. Solutions, expressions, and other items can be selected with the tap of the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pocket Calculators
An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom. Modern electronic calculators vary from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers. They became popular in the mid-1970s as the incorporation of integrated circuits reduced their size and cost. By the end of that decade, prices had dropped to the point where a basic calculator was affordable to most and they became common in schools. Computer operating systems as far back as early Unix have included interactive calculator programs such as dc and hoc, and interactive BASIC could be used to do calculations on most 1970s and 19 ...
