EO Personal Communicator
The EO is an early commercial tablet computer that was created by Eo, Inc. (later acquired by AT&T Corporation), and released in April 1993. Eo (Latin for "I go") is the hardware spin-out of GO. Officially named the AT&T EO Personal Communicator, it is similar to a large personal digital assistant with wireless communications, and competed against the Apple Newton. The unit was produced in conjunction with David Kelley Design, frog design, and the Matsushita, Olivetti and Marubeni corporations. Among the EO customers AT&T claimed were: New York Stock Exchange, Andersen Consulting, Lawrence Livermore Laboratories, FD Titus & Sons and Woolworths. Eo, Inc., 52 percent owned by AT&T, shut down operations on July 29, 1994, after failing to meet its revenue targets and to secure the funding to continue. It was reported that 10,000 of the computers had been sold. In 2012, PC Magazine called the AT&T EO 440, "the first true phablet". Product specifics Two models, the Communicato ...

AT&T Hobbit
The AT&T Hobbit is a microprocessor design that AT&T Corporation developed in the early 1990s. It was based on the company's CRISP (C-language Reduced Instruction Set Processor) design, which in turn grew out of the C Machine design by Bell Labs of the late 1980s. All were optimized for running code compiled from the C programming language. The design concentrates on fast instruction decoding, indexed array access, and procedure calls. Its processor is partially RISC-like. The project ended in 1994 because the Hobbit failed to achieve commercially viable sales. History CRISP was produced in 1987, largely for experimental purposes. Apple Computer approached AT&T and paid it to develop a newer version of the CRISP suitable for low-power use in the Newton handheld computer. The result is the Hobbit, which was initially produced as the 92010 in 1992 with a 3 KB instruction buffer and the 92020 in 1994 with 6 KB. Several support chips were produced: * AT&T 92011 System ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phablet
A phablet (, ) is a mobile device combining or straddling the size formats of smartphones and tablets. The word is a portmanteau of ''phone'' and ''tablet''. Phablets feature large displays that complement screen-intensive activity such as mobile web browsing and multimedia viewing. They may also include software optimized for an integral self-storing stylus to facilitate sketching, note-taking and annotation. Phablets were originally designed for the Asian market where consumers could not afford both a smartphone and tablet as in North America; phones for that market are known for having "budget-specs-big-battery" with large low resolution screens and midrange processors, although other phablets have flagship specifications. Since then, phablets in North America have also become successful for several reasons: Android 4.0 and subsequent releases of Android were suited to large as well as small screen sizes, while older consumers preferred larger screen sizes on smartphones due ...

History Of Tablet Computers
The history of tablet computers and the associated special operating software is an example of pen computing technology, and thus the development of tablets has deep historical roots. The first patent for a system that recognized handwritten characters by analyzing the handwriting motion was granted in 1914. The first publicly demonstrated system using a tablet and handwriting recognition instead of a keyboard for working with a modern digital computer dates to 1956.

Pen Computing
Pen computing refers to any computer user-interface using a pen or stylus and tablet, over input devices such as a keyboard or a mouse. Pen computing is also used to refer to the usage of mobile devices such as tablet computers, PDAs and GPS receivers. The term has been used to refer to the usage of any product allowing for mobile communication. An indication of such a device is a stylus or digital pen, generally used to press upon a graphics tablet or touchscreen, as opposed to using a more traditional interface such as a keyboard, keypad, mouse or touchpad. Historically, pen computing (defined as a computer system employing a user-interface using a pointing device plus handwriting recognition as the primary means for interactive user input) predates the use of a mouse and graphical display by at least two decades, starting with the Stylator and RAND Tablet systems of the 1950s and early 1960s. General techniques User interfaces for pen computing can be implemented in several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GO Corporation
GO Corporation was founded in 1987 to create portable computers, an operating system, and software with a pen-based user interface. It was famous not only for its pioneering work in Pen-based computing but as well as being one of the most well-funded start-up companies of its time. Its founders were Jerry Kaplan, Robert Carr, and Kevin Doren. Mr. Kaplan subsequently chronicled the history of the company in his book ''Startup: A Silicon Valley Adventure''.

PenPoint OS
The PenPoint OS was a product of GO Corporation and was one of the earliest operating systems written specifically for graphical tablets and personal digital assistants. It ran on AT&T Corporation's EO Personal Communicator as well as a number of Intel x86 powered tablet PCs including IBM's ThinkPad 700T series, NCR's 3125, 3130 and some of GRiD Systems' pen-based portables. It was never widely adopted. Developers of the PenPoint OS included Robert Carr, who was involved with the Alto computer at Xerox PARC. He commissioned Dr. Tinker, the naming service company of Mark Beaulieu who generated the name 'PenPoint', using proprietary algorithms. Awards and innovation Byte magazine awarded PenPoint best Operating System in the 1992 Byte Awards.

Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and ...

E-mail
Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic ( digital) version of, or counterpart to, mail, at a time when "mail" meant only physical mail (hence '' e- + mail''). Email later became a ubiquitous (very widely used) communication medium, to the point that in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. ''Email'' is the medium, and each message sent therewith is also called an ''email.'' The term is a mass noun. Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simult ...

Modem
A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by Modulation#Digital modulation methods, modulating one or more carrier wave signals to encode digital information, while the receiver Demodulation, demodulates the signal to recreate the original digital information. The goal is to produce a Signal (electronics), signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio. Early modems were devices that used audible sounds suitable for transmission over traditional telephone systems and leased lines. These generally operated at 110 or 300 bits per second (bit/s), and the connection between devices was normally manual, using an attached telephone handset. By the 1970s, higher speeds of 1,200 and 2,400 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
