From the project
Portable, safe readers for Apollo Guidance Computer core rope memory modules
This repository contains all of the design files for safe, portable Block I and Block II Apollo Guidance Computer (AGC) core rope memory readers. For a detailed explanation of how it all works, check out CuriousMarc's video featuring this project.
The rope readers are designed to be electrically and mechanically exactly identical to real AGCs from the point of view of the rope modules. Exact mechanical dimensions and interfacing circuits were copied from the original AGC engineering drawings, obtained from the National Archives. During bringup, all circuits are calibrated to the original…
