6 Bit L-R Shift Register

This document contains a detailed schematic for the Digital Equipment Corporation (DEC) M212 6-bit left-right shift register, copyrighted in 1967. It features a series of integrated circuits (DEC7474N and DEC7453N) configured for shift register operations with enable inputs for right and left shifting. A full parts list including integrated circuits, resistors, and capacitors is provided along with a transistor and diode conversion chart. This schematic is intended for test and maintenance purposes.
