DCJ11Hack+ – DEC PDP/11 based homebrew computer (codeberg.org)

TechPaula’s Codeberg project shares hardware designs, PAL code, and assembly examples for the DCJ11 Hack+, a homebrew PDP/11-style computer built around a DCJ11 chip with a modular backplane. The repository includes KiCad PCB/schematics for an added CPU board, RAM/ROM/text display board (including a 16x16 dot-matrix display), plus a documented memory map and code demos such as “Hello World,” animation patterns, and a terminal test.
