Nor Gate M112

This document is a technical schematic for the "Nor Gate M112" circuit board, produced by the Digital Equipment Corporation in 1968. The schematic illustrates a logic circuit consisting of several integrated circuits (specifically DEC7402N quad NOR gate ICs), along with associated capacitors and resistors for power filtering and input/output stabilization. The document includes a parts list specifying component values and part numbers, as well as pin configuration notes (pin 7 for GND and pin 14 for +5V). It is provided for test and maintenance purposes.
