| The Convergence/Deflection Board I/O | |
| This section describes the inputs to and outputs from the C/D | |
| Board. The I/O descriptions are arranged by the source and | |
| destination of the signal. The assembly communicated with is the | |
| primary heading of each group of signals. Those signals are | |
| subdivided into inputs and outputs. Input refers to an Input to the | |
| C/D Board, output refers to an output from the C/D Board. | |

CONV | correction is about 1 VPP. | |
Y_RED_ | Red Y convergence waveform. The amplitude for full scale correction | |
CONV | is about 1 VPP. | |
Y_GRN_ | Green Y convergence waveform. The amplitude for full scale | |
CONV | correction is about 1 VPP. | |
Y_BLU_ | Blue Y convergence waveform. The amplitude for full scale | |
