A SOLID-STATE TYPEWRITER AND TAPE-PUNCH CONTROL UNIT

Technical Report ·
OSTI ID:4840799
A recording unit is described which accepts binarycoded input information and stores it using a typewriter and/or a paper-tape punch. Since all the necessary electrical switching is done using solid-state diodes and transistors, the output speed is limited only by the mechanical operation of the recording devices used and electrical interference is eliminated since the rate of change of currents is low and controlled. Operation of the equipment is explained for both 10 and 60 digit per second output devices. (auth)
