NOTES:

- The analog inputs come from the player's depth control potentiometer. The voltage is compared to a voltage ramp provided by a discrete analog circuit that conditions the VBLANK signal. When the ramp voltage exceeds the input voltage an NMI signal is generated. The computer then reads the VSYNC data functions to tell where the cursor should be located. *
