AX08 Diagnostic

This document provides the diagnostic procedures for the AX08 option used with PDP-8, 8L, or 8I computers. It outlines three main testing sections:

• Instruction Test: Tests registers, flip-flops, timing, and clock logic.
• Display Test: Verifies display patterns for deflection logic and amplifier functionality.
• A/D Converter Calibration: Uses a 1000-sample buffer and horizontal sweep display to verify A/D conversion accuracy and system noise levels.

The guide includes loading procedures, operational switch settings for diagnostics, and instructions for operator actions during error conditions.
