M214 Data Storage Register

This document outlines the specifications for the M214 module, which features a 6-bit adder and a 6-bit storage register. Three of these modules work together to create an 18-bit Data Storage Register (DSR) used in the PDP-15 I/O processor for memory and I/O device data exchange. The document provides detailed technical data, including TTL input loading for various connections, output driving capabilities, strobe pulse timing requirements, and power dissipation ratings (5V at 280mA maximum).
