The Tektronix 1240 is a logic analyzer. The 1241 is the same device but with a color-shutter CRT.
The power supply is a switch-mode supply that mainly generates 5 V at up to 45 A. It requires a minimum load of 11.6 A. Additionally it generates 3 V at up to 8 A with no minimum load and several other voltages that are derived from linear post regulators.
Boards are two to six layers.
