KT-Pilot" and "Kyoto University QA-1," computers developed by Dr. Hiroshi Hagiwara (passed away on January 8, 2014), the first president of Kyoto College of The Kyoto College of Graduate Studies for Informatics (KCGI), while he was a student at Kyoto University, were recently recognized as "Heritage of Information Processing Technology" by the Information Processing Society of Japan (IPSJ) in 2013.The "KT-Pilot" is the prototype of the "TOSBAC-3400," a high-speed computer jointly developed by Dr. Hagiwara and Toshiba Corporation, which is preserved and exhibited at the "KCG Museum" of Kyoto Computer Gakuin Kyoto Ekimae School (authorized as Information Processing Technology Heritage No. 1).The certification of these two models proves once again that Dr. Hagiwara is a world authority in computer development, electronic circuits, information theory, and communication methods research, and a pioneer in the Japanese computer world.
The "KT-Pilot" was developed and manufactured jointly by Dr. Hagiwara and Toshiba in 1961, and was the first full-scale micro-programming instrument in Japan.The logic circuit uses a high-speed basic circuit with silicon mesa-type transistors and a parallel asynchronous high-speed arithmetic method.For the memory device, we implemented Japan's first thin-film memory device.Presented at IFIP in Munich in August 1962, it was highly acclaimed as the world's fastest computer.It is preserved and exhibited at the Toshiba Museum of Science and the Future (Saiwai-ku, Kawasaki City).
Kyoto University QA-1 was developed from 1974 to 1977 with the cooperation of many students, mainly Dr. Hagiwara, Dr. Shinji Tomita, Dr. Shigeru Koyanagi, and Dr. Kiyoshi Shibayama of the Faculty of Engineering, Kyoto University, and others, for the purpose of high-speed graphics processing.It is not a dedicated graphics computer, but a more general-purpose device, characterized by the use of a method that allows simultaneous specification of four different ALU operations, four memory accesses, and one sequential control.It is preserved at the National Museum of Nature and Science (Tsukuba City, Ibaraki Prefecture).
In addition to the TOSBAC-3400, there are five other models of "Information Technology Heritage" certified equipment preserved and exhibited at the KCG Museum: the OKITAC 4300C system (first certified in 2008), the NEAC-2206 (certified in 2010), the NEAC S-100 system (certified in 2011), and the Sharp MZ-80K (certified in 2012).
Dr. Hiroshi Hagiwara graduated from Kyoto University with a bachelor's degree in engineering and a doctorate in engineering from the same university.He has served as President of the Information Processing Society of Japan and as a member of the Science Council of Japan.After serving as a professor in the Faculty of Engineering at Kyoto University, a professor in the Faculty of Science and Engineering at Ryukoku University, and the director of the KCG Information Technology Research Institute, he was appointed president of KCGI in April 2004 upon its opening, and served until March 2008.He has contributed greatly to the development of KCGI.In April 2009, he was awarded the Order of the Sacred Treasure, Gold Rays with Neck Ribbon.
