Vertical Drive
The vertical oscillator inside IC2801 starts and outputs ramp signals at IC2801/pin 18 (VD(-)) and IC2801/pin 19
(VD(+)) when power is applied. Data need not be present for vertical drive to output from IC2801.
The vertical stage is has not changed functionally from previous models. The vertical drive signals from IC2801/
pins 18 and 19 are applied to IC5004/pins 1 and 7. The ramp signals are amplified in IC5004 and the output drive
for the V-DY is output at IC5004/pin 5.
