Triple Flip-Flop S203

This document is a technical schematic diagram for a Triple Flip-Flop circuit, manufactured by the Digital Equipment Corporation in 1965. The circuit consists of three interconnected flip-flop stages utilizing transistors (DEC 3639C) and diodes (D-662/D-664). The diagram outlines the wiring for components, including various resistors, capacitors, and diodes, to perform the flip-flop logic function, powered by a 10V and -15V supply system. It also includes component specifications, a conversion chart for the transistors and diodes, and manufacturing revision notes.
