Toshiba Firsts of Their Kind

Notebook PC "DynaBook"

Around 1986, when Toshiba first began developing notebook PCs, computers (especially desktop computers), were becoming increasingly visible in the office environment. The computers of those days used a CRT display monitor, a 3.5-inch hard disk (HDD) with a thickness of 50.8 mm, and a 3.5-inch floppy disk drive (FDD) with a thickness of 25.4 mm. As office automation level advanced from section or department to personal, we sensed people would eventually demand small PC that could be placed on a desk or carried around. To meet this demand, we decided to develop a notebook PC that could be used by anyone, anytime, and anywhere. We characterized this venture in the catchphrases "a revolution on the desktop" and "a revolution in portability".

In creating lightweight, compact PCs, we first assumed various scenarios in which a PC would be used, then chose a design everybody would want. But only parts for desktop PCs were available. To build an ideal notebook PC, we had to set specifications for the parts necessary for a notebook PC and build them from scratch. Working with FDD and keyboard manufacturers, we developed a 19 mm thick ultra-thin FDD and a 15 mm thick keyboard. We also developed a 2.5-inch HDD as a built-in HDD for the DynaBook with a HDD manufacturer - a world's first. Today, the 2.5-inch HDD represents an important area of the computer industry. We developed our first 2.5-inch HDD for our notebook PCs. We determined the specifications and had a HDD maker manufacture the drives to our specifications. We had considered both 2.5-inch and 2-inch HDDs, but finally chose the 2.5 inch factor, foreseeing that this form factor would permit a doubling of capacity every year. We also developed a thin CD-ROM to fit a notebook PC. For the display, working once again with parts manufacturers, we developed flat plasma and LCD monitors. For the battery, we developed nickel hydrogen and lithium ion batteries. IN parts development, even when the parts represented the first of their kind anywhere in the world, we secured at least two vendors to reduce costs and to ensure a reliable supply. For the DynaBook, we had two vendors each for the HDD, FDD, keyboard, LCD, battery, system LSI (once called super integration), as well as every other part. The development of components for the ideal notebook PC resulted in dramatic growth in the markets for high-tech parts and systems, creating a major new industry. Those parts and systems included ultra-thin HDDs, FDDs, CD-ROM drives, DVD-ROM/RAM, and other storage devices; lightweight, thin, power-saving flat plasma or LCD monitors; and nickel hydrogen and lithium ion batteries.

To minimize power consumption, we adopted a computer-controlled power supply - another first - and provided the DynaBook with power conservation functions (e.g., resume, automatic shut-off of the monitor if no key operations were detected for a certain period, CPU slow/stop, FDD or HDD stop). Such functions eventually became core notebook PC functions. The DynaBook was also the first PC bundled with word processor, spreadsheet, and other applications software. We also adopted a world-standard operating system (OS) for the DynaBook when most other Japanese manufacturers relied on their own proprietary operating systems.

In 1986, in another world's first, we developed the J-3100 (T3100 on the overseas market), a commercial laptop PC that incorporated an ultra-thin 3.5-inch HDD. In 1989, we developed a commercial A4-size notebook PC DynaBook (T1000SE on the overseas market), the first of its kind worldwide. In 1996, we developed the still more compact Mininote Libretto. Our efforts led to the development of a lineup of portable, compact, and power saving computers before our competitors. We created a notebook PC market, in which we established a leadership position.

For these new technologies, we won PC Magazine's Technical Excellence award in 1986, the Nikkan Kogyo Shimbun Best Ten New Products Prize in 1987 and 1989, the Nihon Keizai Shimbun award in 1988 and 1989, and an Okochi prize from the Okochi Memorial Foundation.
