(Include date or date range in title. Example: “Alternating Current Electrification, 1886”) Please provide a plaque citation in English summarizing the achievement and its significance. Text absolutely limited by plaque dimensions to 70 words; 60 is preferable for aesthetic reasons. NOTE: The IEEE History Committee shall have final determination on the wording of the citation. Names of living persons are not normally used in citations. Exceptions to this are cases where the person's name is linked to the achievement itself (e.g. the Lempel-Ziv algorithm, Maxwell's Equations, etc.) or where the person's name is so widely recognizeable to the general public that it makes sense to use it. When used, the names should be the names of the engineers, scientists, or technologists who actually made the achievement, rather than managers or executives. For more information and suggestions about writing milestone citations, please visit Helpful Hints on Citations, Plaque Locations. In what IEEE section(s) will the milestone plaque(s) reside? Please specify the IEEE Organizational Unit(s) which have agreed to sponsor the Milestone, and supply name and contact information for the senior officer from those OU(s). Sponsorship has three aspects: 1) Payment for the cost of the plaque(s), 2) Arranging the dedication ceremony, and 3) agreeing to monitor the plaque and to let IEEE History Center staff know in case the plaque needs to be moved, is no longer secure, etc. Number 3 must be done by the IEEE Section(s) in which the plaque(s) is located, but aspects 1 and 2 can be done by any IEEE Organizational Unit, and they need not be the same one. Please note: your email address and contact information will be masked on the website for privacy reasons. Only IEEE History Center Staff will be able to view the email address.

Please include coordinates in decimal format rather than degrees. What is the intended site(s) of the milestone plaque(s) relation to the achievement? The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque. Also, please Describe briefly the intended site(s) of the milestone plaque(s). (e.g. Is it corporate buildings? Historic Site? Residential? Are there other historical markers already at the site?) Are the original buildings extant? Please provide the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. How is the intended plaque site protected/secured, and in what ways is it accessible to the public? If visitors to the plaque site will need to go through security, or make an appointment, please give details as well as the contact information visitors will need in order to arrange to visit the plaque. Who is the present owner of the site(s)? In the space below, please describe in detail: the historic significance of the achievement, its importance to the evolution of electrical and computer engineering and science, its importance to regional/national/international development, its benefits to humanity, the ways the achievement was a significant advance rather than an incremental improvement of existing technology. The material submitted here will constitute the main descriptive article on the ETHW website for readers to learn about the milestone. Space is unlimited, and detail is encouraged. Most milestones require 1000 to 1500 words of support, however there is no word limit. The article should be readable by a wide audience that includes practicing engineers, scholars of history, and the general public. Some examples of the text of good milestone articles are First Radio Astronomical Observations Using Very Long Baseline Interferometry] and G3_Facsimile International Standardization of G3 Facsimile (Do not worry about the formatting of the page, IEEE History Center Staff will do that afterwards.) What is the historical significance of the work (its technological, scientific, or social importance)? Nowadays, people carry their portable PCs and use them anywhere. But until April 1985, with the introduction of Apple II in 1977, IBM PC in 1981, and other clone PCs, personal computing had increasingly been accepted but usages had still been limited in fixed desktop environment. T-1100, released in April 1985, was a real 16 bit lap-top personal computer weighting only 4 kg. Equipped with battery, it provided the user the same computing environment anywhere even without AC power just like in the office. T-1100 was the first clam-shell lap-top computer in the world. It provided the same office/engineering computing environment as a desk-top PC, introduced ubiquitous computing style (Anytime, Anyone, Anywhere), and was used not only in offices but also at homes. After T-1100, the innovation by Toshiba has triggered the growth of lap-top and Note PC market up to $150 billion and, in addition, created the related component industries. (LCD：14 B$ HDD:17B$, Battery:11B$, CPU 34B$） In the last 25 years, Toshiba has sold 100 million personal computers. T-1100 was the origin of “Lap-top Computers”; as all lap-top and notebook computers can be traced back to this model. What obstacles (technical, political, geographic) needed to be overcome? In order to realize portability, operability without AC power, and compatibility with IBM-PC/AT, it was necessary to make it as light as possible and reduce power usage for long battery life. To achieve this, Toshiba had consolidated a great number of ICs which were normally used in desktops PCs into a few Gate Arrays and, instead of the existing mainstream NMOS technology, adopted CMOS technology. With these solutions, T-1100 realized not only compaction and light weight of 4kg, but also low power consumption. In addition, Toshiba had also developed main components such as LCD and 3.5 inches floppy disc drive for achieving the highest density implementation ever before. Toshiba had also developed rechargeable NiCad batteries from the ground and achieved 8 hours battery life. This battery life was realized with the enabling technologies including charge/discharge mechanism and driver software which were not yet available for PC ATs. This technology had been improved to the current “ACPI (Advanced Configuration and Power Interface)” which has been widely used as a common power control standard and enables stand-by/suspend mode and cutting power supply to sleeping devices. Although Clam-shell system is suitable for portable PC to guard LCD and keyboard, there was no clam-shell hinge and FPC (Flexible printed circuits) cable with light and enough durability and endurance. But Toshiba developed these components with countless repeated trials. What features set this work apart from similar achievements? As for portable computing devices prior to T-1100, Compaq released Portable I in 1982, but it came with size of the suitcase, 12.5kg weight, separate display and keyboard. Therefore, although it was portable, it was not light enough to call lap-top. In Japan, HC-20 of Seiko released in 1982 and PC8201A of NEC released in 1983 were about 1.7kg handheld device, but were 8 bit BASIC machine not compatible with IBM PC/AT. T-1100 was the first clam-shell lap-top computer with IBM-PC/AT compatibility and workable without AC power.
