`
`It all started in August of 1987 when
`GO Corporation was founded by Jerry
`Kaplan, formerly of Lotus
`Development Corp, to create his
`dream a leadingedge, handheld,
`penoperated computer, which he first
`envisioned a few months earlier in
`February 1987.
`
`After two years of work and million of
`dollars, in June of 1989, GO Corp.
`had a hobbledtogether partially
`working prototype to demonstrate to
`investing partners. State Farm
`Insurance and IBM were two of their
`largest potential customers.
`
`After another two years, in April
`1991, their PenPoint operating
`system "developers release" is
`completed and available to thirdparty
`developers. Designed to run on Intel
`CPUbased systems, it is an entirely new computer operating system, not just an addition to MSDOS, utilizing a notebooklike userinterface
`with graphical icons, draganddrop capabilities, and dozens of simple penbased gestures for document editing and onscreen navigation.
`
`Later that year, BYTE magazine awards GO's PenPoint operating system their Award of Excellence in their annual Best Products edition.
`
`While GO did produce a model G400 prototype, they were having difficulties developing both the software and hardware aspects, and to
`appease their largest investor IBM, in July 1991 GO spunoff a separate and independant company named "EO Inc." ("eo" is Latin for "go")
`GO would concentrate on the software, EO would produce and market the hardware. AT&T becomes a major investor in new EO, owning 20%
`of the company.
`
`AT&T also buys Active Book Company, who is working on a simlar project, utilizing the ARM processor, just months from release. Active
`Book Company is dissolved and incorporated into EO. This new company will concentrate on producting a penbased system using AT&T's
`new Hobbit CPU chipset, which was originally developed for the Apple Newton, a competing penbased portable computer system from Apple
`Computer. Unsatisified with the Hobbit, the Apple Newton eventually went with the ARM processor instead.
`
`In April of 1992, GO released PenPoint version 1.0 to all interested thirdparty developers. IBM announces their ThinkPad 700T (model 2521)
`handheld penbased tablet, running the PenPoint operating system, to ship in October 1992. NCR and GRiD also announce products running
`PenPoint OS.
`
`Within 16 months of spinningoff from GO, EO's 440 Personal Communicator, not yet for sale, was demonstrated in the AT&T booth at the
`Fall 1992 COMDEX show, in Las Vegas, NV. The industrial design (basically the ears on the sides to differentiate it from competitors) was by
`Frog Design, Inc.
`
`The EO440 and it's larger sibling the EO880 were available to the public on April of 1993. They were
`advanced but expensive, with the most basic system going for almost $2,000.
`
`Every EO owner received a free subscription to AT&T EasyLink Mail for both fax and email
`messages.
`Included with and installed in every EO are these penbased software packages:

`EO880 w/ 4MB RAM

`
`The AT&T Hobbit chipset is composed
`of four large chips, which consume a
`large portion of the system motherboard.
`Other prominent chips are by Wacom,
`for their electromagnetic resonance pen
`sensing technology, with additional
`components incorporated into the LCD
`display.
`
`The optional EO440 internal hard drive
`is the tiny and amazing Kittyhawk 20MB
`1.3inch microdrive from Hewlett
`Packard, at the time the smallest hard
`drive in the world. Fragile? No a builtin
`accelerometer parks the drive heads to
`protect itself from hard falls, in fact
`making it the most reliable hard drive
`available. Kittyhawk was claimed to be
`able to survive a 3foot drop onto
`concrete while operating without loss of
`data perfect for use in a handheld
`portable computer system. The Dauphin
`DTR1 from 1993 also utilized the tiny
`Kittyhawk hard drive.
`
`For removeable mass storage, consider
`the SunDisk (not SanDisk) PCMCIA
`flash card, which allows quick and easy,
`but very expensive, data storage
`expansion. Sizes available include:
`1.8MB ($249), 5MB ($449), 10MB
`($749), 20MB ($1,199).
`
`The larger (13x9x1inch, 4.0 lbs) and
`more powerful EO880 ($2,499) has a
`faster CPU 30MHz instead of 20MHz,
`and a larger 9.4inch display, which is
`backlit instead of reflective as in the EO
`440. A larger 64MB hard drive ($699) as
`well as VGA, SCSI, and a second
`PCMCIA port roundout this powerful
`system.
`
`Using the serial port and included
`software, Both EO440 and EO880 can communicate with IBMcompatible machines for sending and retrieving data.
`The parallel port is to connect to laser and dotmatrix printers, and data storage on the optional external 31/2 inch 1.44MB floppy drive.
`A standard PS/2 connector allows the use of an external PCcompatible keyboard for heavy data entry.
`
`GO and EO both had a hard time of it, though, as cheaper but less capable systems were available from other companies, and predatory
`Microsoft had effectively locked them out of the Intelbased market. In June of 1993, AT&T acquired a majority 51% stake in EO, and in
`August buys GO entirely, combining the two companies into EO, only to shut it down entirely in July 1994 when it was obvious that their
`products were selling poorly. It is estimated that about 10,000 EO systems were sold.
`
`Kaplan, the founder of GO, wrote a book about his experiences at GO Corporation entitled "StartupA Silicon Valley Adventure", published in
`May of 1995 by HoughtonMifflin.
