Description
The FACOM 668K was Fujitsu's high-performance card reader for the FACOM230-5 Series and FACOM 230-8 Series. It could read 80-column cards at a high speed of 2,000 cards per minute (maximum). At the time, large high-performance computers were used in computing centers, and a high-speed, easy-to-operate and high-reliability data input unit was needed for inputting a diverse variety of data at high speed.
