FOUR FLIP-FLOPS B204

This document is a proprietary schematic diagram from Digital Equipment Corporation, copyrighted in 1964, intended solely for test and maintenance purposes. It details the circuit design for "FOUR FLIP-FLOPS B204." The schematic illustrates multiple identical flip-flop sections, primarily utilizing transistors (DEC2894-IB), diodes (D-664 and D-662 types, with EIA equivalents IN3606 and IN645 noted), resistors (1/4W, 5%), and capacitors (MMFD). The drawing was prepared in June 1964.
