FACOM 731S Card Reader and Line Printer

The FACOM 731S was developed to meet these needs. In a single console, it provided a card reader -- using the vertical feed system for reading 12 rows simultaneously, with a read speed of 300 cards per minute -- and a line printer with a print speed of 360~440 lines per minute (with 136 characters per line). This unit was designed to conform to Fujitsu's FACOM low-speed input/output interface conventions, and just like units such as paper tape devices, it was connected to the IOC (Input/Output Controller), or a channel MBC (Multiple Basic Channel) with a built-in input/output control function.
