PDP-8, 8/I Extended Memory Address Test

This document describes the PDP-8, 8/I Extended Memory Address Test (MAINDEC-08-D1HA-D). The diagnostic verifies that all memory locations not occupied by the program can be uniquely addressed through a series of four tests that involve writing address and complement patterns, as well as checking bit errors with alternating ones and zeros. The document includes requirements for the test, loading and starting procedures, and specific instructions for the operator to set test limits via the Teletype keyboard.
