Wells-Garnder Color Vector Monitor Guide

This gives reference frames for when the monitor is mounted horizontally (for games like Space
Duel and Major Havoc conversions) and vertically (for games like Tempest).
An easy way to remember which kind of transistor goes where is to know that each connector
has one of each kind; the 2N3716s are on pins 1, 3, and 4 (key at pin 2) and the 2N3792s are on
pins 5, 6, and 7. If the wiring has not been altered, all 2N3716s are connected to the yellow,
green, and red wires and all 2N3792s are connected to the purple, blue, and white wires. Here are
2 diagrams of the layout as viewed from the top:

or, more simply (where 2 = 2N3792 and 6 = 2N3716):
