ABSTRACT:
Clocking circuitry for a character generator wherein a control microprocessor controls character generated by hardwired logic through an interface microprocessor, the clocking circuitry including an oscillator which supplies an output to a divider which supplies a reduced frequency signal to the control microprocessor. The output of the oscillator is also supplied to the output of a timing controller. The timing controller further receives a print signal from the interface microprocessor and supplies a plurality of timing signals to the hard wired logic character generator.
