Pdp-8i Switch Connector G793

This document is a technical schematic for the Digital Equipment Corporation G793 Switch Connector, dated 1968. The circuit consists of 13 input channels (labeled D through V) that utilize a diode-resistor network to interface with +5V and -15V power rails through a "Flexprint" connection. The document includes a parts list specifying the required resistors (6.8K and 1.5K) and diodes (D664), as well as a transistor and diode conversion chart. It is marked as proprietary material intended for test and maintenance purposes.
