Set-Reset Flip Flop Module M203

This document contains the engineering schematic for the M203 Set-Reset Flip Flop module designed by Digital Equipment Corporation in 1967. The diagram illustrates the circuit logic using E1 through E4 integrated circuits (DEC 7400N). It also provides a parts list, including capacitors (C1-C4) and ICs, along with specific pin voltage requirements (Pin 7 for GND, Pin 14 for +5V).
