Description
The interface for connecting between these tape readers and the computer main unit varied depending on the computer model, so special-purpose tape readers were developed for the FACOM 222/241 and FACOM 231. However, with the FACOM 230-30 (announced in April 1964) and subsequent models, the interface was standardized, and the FACOM 749A and FACOM 749B/749E (employing that standard interface) were used with many computers.
