Lisp machines are general-purpose computers designed to efficiently run Lisp as their main software and programming language, usually via hardware support. They are an example of a high-level language computer architecture, and in a sense, they were the first commercial single-user workstations. Despite being modest in number Lisp machines commercially pioneered many now-commonplace technologies, including effective garbage collection, laser printing, windowing systems, computer mice, high-resolution bit-mapped raster graphics, computer graphic rendering, and networking innovations such as Chaosnet. Several firms built and sold Lisp machines in the 1980s: Symbolics, Lisp Machines Incorporated, Texas Instruments, and Xerox. The operating systems were written in Lisp Machine Lisp, Interlisp (Xerox), and later partly in Common Lisp.
Fujitsu Limited is a Japanese multinational information and communications technology equipment and services corporation, established in 1935 and headquartered in Tokyo. Fujitsu is the world's sixth-largest IT services provider by annual revenue, and the largest in Japan, in 2021. The hardware offerings from Fujitsu are mainly of personal and enterprise computing products, including x86, SPARC and mainframe compatible server products, although the corporation and its subsidiaries also offer a diversity of products and services in the areas of data storage, telecommunications, advanced microelectronics, and air conditioning. It has approximately 126,400 employees and its products and services are available in approximately 180 countries.

ISO/IEC 646 is a set of ISO/IEC standards, described as Information technology — ISO 7-bit coded character set for information interchange and developed in cooperation with ASCII at least since 1964. Since its first edition in 1967 it has specified a 7-bit character code from which several national standards are derived.
ISO/IEC 8859-8, Information technology — 8-bit single-byte coded graphic character sets — Part 8: Latin/Hebrew alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings. ISO/IEC 8859-8:1999 from 1999 represents its second and current revision, preceded by the first edition ISO/IEC 8859-8:1988 in 1988. It is informally referred to as Latin/Hebrew. ISO/IEC 8859-8 covers all the Hebrew letters, but no Hebrew vowel signs. IBM assigned code page 916 to it. This character set was also adopted by Israeli Standard SI1311:2002, with some extensions.
ISO/IEC 2022Information technology—Character code structure and extension techniques, is an ISO/IEC standard in the field of character encoding. Originating in 1971, it was most recently revised in 1994.
The FM Towns is a Japanese personal computer, built by Fujitsu from February 1989 to the summer of 1997. It started as a proprietary PC variant intended for multimedia applications and PC games, but later became more compatible with IBM PC compatibles. In 1993, the FM Towns Marty was released, a game console compatible with existing FM Towns games.
The Fujitsu FACOM VP is a series of vector supercomputers designed, manufactured, and marketed by Fujitsu. Announced in July 1982, the FACOM VP were the first of the three initial Japanese commercial supercomputers, followed by the Hitachi HITAC S-810 in August 1982 and the NEC SX-2 in April 1983.
FUJIC was the first electronic digital computer in operation in Japan. It was finished in March 1956, the project having been effectively started in 1949, and was built almost entirely by Dr. Okazaki Bunji. Originally designed to perform calculations for lens design by Fuji, the ultimate goal of FUJIC's construction was to achieve a speed 1,000 times that of human calculation for the same purpose – the actual performance achieved was double that number.
Toshio Ikeda was a Japanese engineer. He was the former managing director of Fujitsu and was the pioneer of domestic computer production in Japan.
The National Aerospace Laboratory of Japan (NAL) was established in July 1955. Originally known as the National Aeronautical Laboratory, it assumed its present name with the addition of the Aerospace Division in 1963. Since its establishment, it has pursued research on aircraft, rockets, and other aeronautical transportation systems, as well as peripheral technology. NAL was involved in the development of the autonomous ALFLEX aircraft and the cancelled HOPE-X spaceplane.
JIS X 0201, a Japanese Industrial Standard developed in 1969, was the first Japanese electronic character set to become widely used. It is either a 7-bit encoding or an 8-bit encoding, although the 8-bit form is dominant for modern use. The full name of this standard is 7-bit and 8-bit coded character sets for information interchange (7ビット及び8ビットの情報交換用符号化文字集合).
The transistor count is the number of transistors in an electronic device. It is the most common measure of integrated circuit complexity. The rate at which MOS transistor counts have increased generally follows Moore's law, which observed that the transistor count doubles approximately every two years. However, being directly proportional to the area of a chip, transistor count doesn't represent how advanced corresponding manufacturing technology is, which is better characterized by transistor density instead.
A mechanical computer is a computer built from mechanical components such as levers and gears rather than electronic components. The most common examples are adding machines and mechanical counters, which use the turning of gears to increment output displays. More complex examples could carry out multiplication and division—Friden used a moving head which paused at each column—and even differential analysis. One model, the Ascota 170 accounting machine sold in the 1960s calculated square roots.
PFU Limited is a Japanese information technology company. The company was formed by the merger of Panafacom and USAC Electronic Industrial in 1987.
The Information Processing Society of Japan ("IPSJ") is a Japanese learned society for computing. Founded in 1960, it is headquartered in Tokyo, Japan. IPSJ publishes a magazine and several professional journals mainly in Japanese, and sponsors conferences and workshops, also mainly conducted in Japanese. It has nearly 20,000 members. IPSJ is a full member of the International Federation for Information Processing. Its current president is Katsumi Emura, appointed in 2020.
Akira Nakashima was a Japanese electrical engineer of the NEC.
The character sets used by Videotex are based, to greater or lesser extents, on ISO/IEC 2022. Three Data Syntax systems are defined by ITU T.101, corresponding to the Videotex systems of different countries.
FACOM is a trademark used for Fujitsu's computers. The first product is FACOM 100, built in 1954. In May 1990, the brand name of FACOM was abolished and changed to Fujitsu.
The FACOM 128 was a relay-based electromechanical computer built by Fujitsu. Two models were made, namely the FACOM 128A, built in 1956, and the FACOM 128B, built in 1959. As of 2019, a fully working FACOM 128B is still in working order, maintained by Fujitsu staff at a facility in Numazu in Shizuoka Prefecture.
