AX08 Laboratory Peripheral

This document provides a detailed description of the AX08 Laboratory Peripheral, designed to integrate analog-to-digital conversion, multiplexing, Schmitt triggers, clocking, and display control into a single unit for PDP-8/L or PDP-8/I computer systems. It covers the basic elements, including the ADC section, crystal and RC clocks, the Enable register, and the External register. The guide details operational flow, timing considerations, optional modules like the XR (expansion for digital inputs/outputs and brightness control) and XM/XC (analog section expansion), and technical specifications for the analog inputs and amplifier performance.
