Comparator

This document is a technical schematic and parts list for a "Comparator" circuit (Module K522-YA-1) produced by the Digital Equipment Corporation in 1971.

The schematic details the electrical configuration of the comparator, which utilizes DEC 6534D transistors and D600 diodes. The design features a symmetrical arrangement of components, including various resistors, capacitors, and transistors, organized around input signals (labeled S and T) and an output section. The document also includes a comprehensive parts list, identifying the specific electrical components required for assembly, as well as a transistor and diode conversion chart for maintenance and testing purposes.
