Variable Delay M360

This document is a technical schematic for the "Variable Delay M360" circuit designed by Digital Equipment Corporation in 1967. The circuit utilizes integrated circuits (DEC7400N and DEC7440N), transistors, diodes, resistors, and capacitors to provide a signal delay function. The document includes a detailed parts list specifying component values and part numbers, a transistor and diode conversion chart, and standard operating notes indicating that pin 7 is grounded and pin 14 is connected to +5V.
