Mq Register

This document is a technical schematic diagram for an "MQ Register" circuit (part number RS-C-R212). The circuit utilizes a dual-transistor flip-flop configuration (using DEC 3639 transistors) combined with multiple DCD (Diode-Capacitor-Diode) logic gates. It features inputs for "Shift Left," "Shift Right," and "AC to MQ" transfers, along with "1" and "0" output terminals. The schematic includes detailed component specifications, noting that resistors are 1/4W 5% tolerance and most diodes are D-664 or D-662 types, operating on a -15V power supply.
