These are typical files that are in Gerber format that lets a fabrications
house make the pcb's

Program that read and generates these files is PROTEL ADVANCED PCB. It is
not a free tool, but you may be able to get a demo from protel
(www.protel.com). If you are going to make any of the pcb's that I
designed, you may want to check with the list, as others may want to get
some as well. For the CPU board, I'm not sure what was used for the design.
