Data-Communication Set

- DESCRIPTION OF OPERATING COMPONENTS -

THE PAGE PRINTER - is operated from the local keyboard or tape readers, or from incoming on-line serial signals from external equipment. Information is typed on sprocket-fed business forms, or as plain message copy. All alphabet characters are in "caps" only.

THE TAPEPUCH - like the page printer, is operated from the local keyboard or tape readers, or from incoming on-line serial signals from external equipment. In this case, information is code-punched into I-inch wide, continuous roll tape.

THE TWO TAPE READERS - sense information codes in punched tape to operate the local page printer and tape punch, or to transmit on-line serial signals to external equipment. The two tape readers can be arranged as a "flip-flop" reading operation, in which specific sections of each tape are intermixed at programmed intervals, resulting in the transmission of blended information. The tape readers can be conditioned to "STOP" from a programmed code in the tapes to permit the introduction of additional information. They can also be s topped by keyboard control. When required, character-by-character stepping of the tape readers can be accomplished from keyboard controls. Each tape reader is equipped with the "tight-tape" stop "end of tape" stop and "free wheeling" feature to facilitate insertion of tape.   

THE KEYBOARD - is a 4-row arrangement similar to the standard typewriter keyboard, having in addition, various on-line and local control keys for functions such as tabulation, combined carriage return and line feed, form out, etc. It also contains other buttons and switches for controlling local operations only. The keyboard is used to operate the local page printer or tape punch, or to transmit 'on-line serial signals to external equipment .
