Control For Cr 8I

This document is a technical schematic diagram for the Digital Equipment Corporation M716 "Control for CR 8I" module.

The schematic details a transistor and diode conversion circuit. It features a series of logic gates (E1, E5, E13) connected to various input/output buses, leading into a configuration of integrated circuits (labeled E2 through E11) organized by "Zones." The diagram includes associated passive components such as resistors (R1-R6), capacitors (C1-C23), and diodes (D1-D4). A comprehensive parts list is provided in the bottom right corner, listing the specific integrated circuit types (DEC 7440N, 7430N, 7400N, 7474N, 7401N) and component specifications necessary for the assembly and maintenance of this circuit board.
