Figure 4: The CLAS-300. Top left: CLAS-300 with central alpha - numeric display keyboard and three remote universal data entry terminals. Top right: data entry on the CLAS-300 (note the large size of the computer components, as well as the magnetic tape-based storage). Bottom left: the CLAS-300's line printer; this particular model, which featured a speed of 300 lines per minute, was considered an incredibly fast printer by 1970's standards. Bottom right: the CLAS-300's central input station; though a large unit, this station was - like the smaller remote data entry terminals: A "dumb" terminal that merely reflected the state of the mainframe that powered it.
