A detailed walkthrough of restoring and interfacing with an HP 1345A vector display, the same hardware used in the 1983 film War Games. The project involves troubleshooting multiple units, building custom power cables, creating an ESP32-based parallel bus bridge, and developing Python software to drive the display. The implementation includes rendering effects like starfields and a playable Asteroids game, while exploring the technical constraints of vector displays including refresh rates, line budgets, and the differences between storage tube and live refresh systems.
