Computers “KT-Pilot” and “Kyoto University QA-1”, developed by Dr. Hiroshi Sugawara, the first president of Kyoto University of Information Studies (KCGI), passed away on January 8, 2014. It was certified as “Information Technology Heritage” in 2013 by the Information Processing Society of Japan.Among them, “KT-Pilot” is a high-speed computer “TOSBAC-3400” (Information Processing Technology Heritage No. 2) that was jointly developed by Prof. Sugawara and Toshiba Corporation and stored and displayed at the “KCG Museum” at Kyoto Computer Gakuin Kyoto Station. (No. 1 certified) prototype.The certification of these two models can be said to have proved again that Prof. Sugawara is a global authority in computer development, electronic circuits, information theory, and communication system research, and a pioneer in the Japanese computer world.
“KT-Pilot” was developed and manufactured in 1961 by Prof. Sugawara and Toshiba, and it is the first device in Japan that uses a full-scale microprogram method.The logic circuit uses a high-speed basic circuit with silicon mesa transistors and adopts a parallel asynchronous high-speed arithmetic method.The first thin-film memory device in Japan was implemented as the memory device.Announced at IFIP held in Munich in August 1962, it was highly regarded as the world's fastest computer.It is preserved and displayed at the Toshiba Future Science Museum (Sachi Ward, Kawasaki City).
“Kyoto University QA-1” has a purpose of high-speed graphics processing. From 1974 to 1977, in addition to Prof. Sakakibara, many students led by Toshiharu Tomita, Shigeru Koyanagi, and Kiyoshi Shibayama from the Faculty of Engineering, Kyoto University. Developed with the cooperation ofThe feature is that it is not a dedicated graphics computer but a more general-purpose device that can specify four different ALU operations, four memory accesses, and one sequence control at the same time.It is preserved at the National Science Museum (Tsukuba City, Ibaraki Prefecture).
In addition to “TOSBAC-3400”, “OKITAC 4300C system” (2008, first certification), “NEAC-2206” (2010) There are five models: NEAC S-100 System (certified in 2011) and Sharp MZ-80K (certified in 2012).
Hiroshi Sugawara is a graduate of the Faculty of Engineering, Kyoto University, and a doctorate in engineering.He has served as president of the Information Processing Society of Japan and a member of the Japan Science Council.After working as a professor at Kyoto University, a professor at Ryukoku University, and a director of KCG Institute of Information Technology, he was appointed president at the same time as KCGI opened in April 2004 and continued until March 2008.A great contribution to the development of KCGI.In April 2009, he was awarded the Zuiho Zhongxiao.
