8x6 Data Mixer M178

This document is a technical schematic for an 8x6 Data Mixer (Part Number M178-0-1) designed by the Digital Equipment Corporation in 1970. The circuit diagram illustrates the routing and connections of various input signals (such as AH1, AE2, AF2, etc.) through an array of logic gates (E1 through E12). It includes power supply specifications, noting that the integrated circuits use Pin 7 for ground and Pin 14 for +5V. The document also specifies the types of integrated circuits used, specifically DEC 74H62 and DEC 74H53, and lists the capacitor values required for the circuit.
