Io Device Control M7100

This document is a technical schematic for an "IO Device Control" module (M7100). The diagram details the electrical circuitry, including a decoder, comparator, and various integrated circuits (such as DEC74H04, 8242, 8251, and 74H74) used for signal processing.

Key features include:

• Signal Pathways: Logic for PI response enable, PI sync, device request, and IOB reset lines.
• Components: The document includes a bill of materials listing specific hardware components, including resistors, capacitors, integrated circuits, and a printed circuit board.
• Specifications: It outlines power requirements (+5V), grounding, and component-specific ratings for the described circuitry.

This schematic was produced by Digital Equipment Corporation in 1970 for test and maintenance purposes.
