- Project shares DCJ11 Hack+ boards and code, heavily inspired by Beent Hilpert's PDP11 Hack, with a backplane for modularity.
- Main boards include a CPU board, RAM/ROM/text display board, and a 16x16 dot matrix display with dual brightness levels.
- Default boot enters ODT mode at 115200 baud (8N1) for debugging; memory map supports RAM, ROM, text display, and matrix display, with word-only access.
- Code examples include Hello World, Knight Rider animation, and terminal tests, compiled via a PDP-11 simulator.
- Uses KiCAD for schematics, PAL files, and relies on eBay backplanes; project moved from GitHub to Codeberg as of March 2026.
