From the project
An Amiga 2000 PCB in the EATX form factor.
This is an open source Amiga 2000 PCB in the EATX form factor. EATX is an ATX variant that defines larger PCBs, measuring 12 x 13 inches (305 × 330 mm). These are referred to as Extended ATX, or, EATX (see Enterprise Electronics Bay Specification). The length of Zorro II cards and the abundance of components on the Amiga 2000 makes EATX the best choice for this project.
