One Shot Delay M304

This document is a technical schematic for a "One Shot Delay M304" circuit board, manufactured by the Digital Equipment Corporation in 1969. The schematic details the logic gate configuration—utilizing DEC7440, DEC7400, and DEC7402 integrated circuits—alongside a network of resistors, capacitors, and diodes. It includes component specifications, such as resistance and capacitance values, as well as a transistor and diode conversion chart for maintenance and testing purposes.
