M218 Mq Register

Summary The M218 module is a 9-bit storage register featuring input gating and shifting logic. When two of these modules are combined, they form an 18-bit MQ register for the PDP-15 central processor (equipped with the EAE option), which supports high-speed arithmetic operations and double-precision calculations. The document also details the module's electrical specifications, including TTL load requirements for inputs and outputs, and its maximum power dissipation (5V at 310 mA).
