Japan Semiconductor Innovation 50 (A-5 1960s)
LSI based Desk Top Calculator (Sharp)
Sharp (then Hayakawa Denki Kogyo) announced the first LSI
based desk top calculator in the world and succeeded in its mass production
in 1969. This new machine was named "Microcompet QT-8D", and its
feature largely surpassed conventional ones with respect to its small size,
light weight, low power, and low cost.
North American Rockwell did the development and production of the kits of
four LSI's and this was the first case where the company's military application
technology was implemented into consumer products.
This announcement sent a clear message to the semiconductor companies domestically
and abroad that the age of LSI arrived, and played an important role to
the evolution of the industries.
