Big Mess O’ Wires (BMOW) announced this morning that they were releasing the Yellowstone controller card to the public. The release makes the cards a Creative Commons license open source project.

Yellowstone is a Liron compatible disk controller for the Apple II. The original Liron cards were created in 1985 but this card uses FPGA to handle all aspects of the cards control features.
