Operating Instructions:
Photo shows the tester installed onto a System 6 CPU board. One alligator clip goes to a +5v source, the other to a ground location.
Power input is non-polarized, so it doesn't matter which wire is connected to +5v power or ground. Don't short them out when attaching alligator clips. You may typically use TP9 and TP10 on system 3-7 CPU boards. Be careful on system 6 boards, the test points are very close together.
Three operating modes are available by pressing and stepping through the 'Mode Select' switch.
