Comparison of the EO 440 Personal Communicator (1993) and the Amazon Kindle 2 e-book reader (2009). Both have reflective displays (no backlight). The EO has a liquid crystal display, the Kindle an electrophoretic one.
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.[3]
In 2012, PC Magazine called the AT&T EO 440, "the first true phablet".[4]
Product specifics
Two models, the Communicator 440 and 880, were produced and measure about the size of a small clipboard. Both are powered by the AT&T Hobbit chip, created by AT&T specifically for running code written in the C programming language. They feature I/O ports such as modem, parallel, serial, VGA out and SCSI. The devices come with a wirelesscellular networkmodem, a built-in microphone with speaker, and a free subscription to AT&T EasyLink Mail for both fax and e-mail messages.
The operating system, PenPoint OS, was created by GO Corporation. Widely praised for its simplicity and ease of use, the OS did not gain widespread use. The applications suite, Perspective, was licensed to EO by Pensoft.
The MessagePad is a discontinued series of personal digital assistant devices developed by Apple Computer for the Newton platform in 1993. Some electronic engineering and the manufacture of Apple's MessagePad devices was undertaken in Japan by Sharp. The devices are based on the ARM 610 RISC processor and all featured handwriting recognition software and were developed and marketed by Apple. The devices run Newton OS.
Fax, sometimes called telecopying or telefax, is the telephonic transmission of scanned printed material, normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine, which processes the contents as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines transmit an audio-encoded digital representation of the page, using data compression to more quickly transmit areas that are all-white or all-black.
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.
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.
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 design resembling the classic RISC pipeline, and 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.
General Magic was an American software and electronics company co-founded by Bill Atkinson, Andy Hertzfeld, and Marc Porat. Based in Mountain View, California, the company developed precursors to "USB, software modems, small touchscreens, touchscreen controller ICs, ASICs, multimedia email, networked games, streaming TV, and early e-commerce notions." General Magic's main product was Magic Cap, the operating system used in 1994 by the Motorola Envoy and Sony's Magic Link PDA. It also introduced the programming language Telescript. After announcing it would cease operations in 2002, it was liquidated in 2004 with Paul Allen purchasing most of its patents.
Delrina Corporation was a Canadian software company active from 1988 to 1995. The company was best known for WinFax, a software package which enabled computers equipped with fax modems to transmit copies of documents to standalone fax machines or other similarly equipped computers. It also sold PerForm and FormFlow, electronic form software. Delrina was acquired by the American software firm Symantec in 1995.
The Apple USB Modem is a combined 56 kbit/s data modem and 14.4 kbit/s fax external USB modem introduced by Apple Inc. after the internal 56k modem was dropped on the October 12, 2005 iMac G5 revision. While it looks similar, it should not be confused with Apple's optional USB Ethernet Adapter accessory, available for its MacBook Air and MacBook Pro Retina range of laptops since 2008.
WinFax is a discontinued Microsoft Windows-based software product developed and published by Delrina designed to let computers equipped with fax-modems communicate directly to stand-alone fax machines, or other similarly equipped computers.
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens 7 inches (18 cm) or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops, tablets usually run mobile operating systems, alongside smartphones.
Internet fax, e-fax, or online fax is the use of the internet and internet protocols to send a fax (facsimile), rather than using a standard telephone connection and a fax machine. A distinguishing feature of Internet fax, compared to other Internet communications such as email, is the ability to exchange fax messages with traditional telephone-based fax machines.
The term personal communicator has been used with several meanings. Around 1990 the next generation digital mobile phones were called digital personal communicators. Another definition, coined in 1991, is for a category of handheld devices that provide personal information manager functions and packet switched wireless data communications capabilities over wireless wide area networks such as cellular networks. These devices are now commonly referred to as smartphones.
The Tandy Memorex Video Information System (VIS) is an interactive, multimedia CD-ROM player produced by the Tandy Corporation starting in 1992. It is similar in function to the Philips CD-i and Commodore CDTV systems. The VIS systems were sold only at Radio Shack, under the Memorex brand, both of which Tandy owned at the time.
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.

The Ciright Platform also provides immediate mobile extendability to an enterprise's legacy system.
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.
Digital Ocean, Inc., was founded in 1992 by Jeffery Alhom. Digital Ocean was a maker of wireless products from 1992 until it was disbanded in 1998.
