PDP-8/E Extended Memory Parity Checkerboard Diagnostic, LS8E Line Printer Test, and RK8E Diskless Control Test

This document outlines the operational specifications and starting procedures for three distinct diagnostic programs for the PDP-8 computer family:

• PDP-8/E Extended Memory Parity Checkerboard Diagnostic: Used to detect memory parity failures under worst-case noise and data patterns in systems with 8K to 32K of core memory.
• LS8E Line Printer Test: Validates the control interface and character generation logic for Centronics model 101 line printers.
• RK8E Diskless Control Test: Checks the RK8E disk control logic without requiring an actual disk drive connected.

Each section includes specific hardware requirements, loading methods via binary loader, and detailed switch register settings for customizing test execution, such as looping, error reporting, and program relocation.
