Facit's OEM version of Sharp Corporation's landmark
Sharp QT-8D
Large-Scale Integration calculator. The QT-8D was the first
electronic calculator (if you don't count the incredible 1965-vintage
Victor 3900)
to utilize a large-scale integration MOS chipset (developed
and fabricated by US chipmaker Rockwell under contract to Sharp) to provide
the four-chip calculating logic of the machine. The Facit 1114 re-packages
the QT-8D's electronics, which were provided to Facit by
Sharp through an OEM (Original Equipment Manufacturer) agreement
between the two companies. Introduced in 1970.
AC-powered,eight digit, four-function calculator with automatic floating
decimal. Utilizes eight Itron vacuum-fluorescent display tubes.
