Diode Gate B134

This document is a technical schematic for a Digital Equipment Corporation Diode Gate circuit (B134). It depicts an array of eight transistor-diode circuits utilizing 2N4258 transistors and D664/D662 diodes. The circuit operates using power rails of +10V and -15V, with specific resistor values (7,500 ohms and 68,000 ohms) and capacitor values (.01 MFD) defined for the logic configuration. The diagram includes a transistor and diode conversion chart for the components used in the design.
