Description
Kölsch is an experimental single-board FPGA computer designed for timeless and retro applications/games.
Note: We’re starting to make a limited number of Kölsch boards available to developers. Kölsch has not yet been fully tested successfully and may contain hardware bugs that limit functionality. This note will be removed once all functionality has been tested successfully. Thanks for your patience.
