Eight Inverters

This document is a technical schematic diagram for the Digital Equipment Corporation "Eight Inverters" circuit (K138), copyrighted in 1970. The schematic details the configuration of eight transistor-based inverter circuits, each utilizing multiple diodes and resistors. The document also includes a transistor and diode conversion chart, listing the standard component equivalents (D600/1N4009 and DEC653I/MPS653I) and provides default specifications for resistors, capacitors, and diodes used in the circuit.
