PDP-11/74 Multiprocessor System Evaluation

This document details the preliminary evaluation plan for the 11/74 Multiprocessor System, aimed at verifying that modifications made to the 11/70 processor for multiprocessor support do not degrade performance or software compatibility. It covers the dual CPU configuration as the primary focus, while addressing potential quad CPU upgrades. The evaluation will assess device performance integrity, electrical characteristics, software compatibility (specifically with RSX-11M-PLUS), system configuration rules, and human factors. The plan includes a detailed time schedule, test configurations, and the necessary peripherals for the evaluation, such as the RH70-C Massbus adapter and the MKA11 multiport memory.
