Wang 701 Output Writer
The Wang 701 Output Writer is a Wang-modified IBM Selectric I (Model 72) electric typewriter. Wang's modifications involve adding numerous soleniods and linkages that allow the solenoids to electrically operate the typewriter. The modifications require a spacer between the base of the typewriter and the main body to accomodate the additional room required for the solenoid mechanisms. Along with the mechanical modifications, a circuit board in the base of the typewriter serves to translate the codes coming from the 700-series calculator connected to the 701 into the necessary solenoid and timing actions to drive the typewriter. Special program codes on the 700-series calculator allow full control of the typewriter to allow fully formatted output to be generated.
