Thanks to Bill Westfield now we have a beautiful ready to made PCB!

I've uploaded in the Files section all the Eagle files (schematic + PCB) zipped as 4chipZ80-Eagle-PCB.zip.
There are two versions, the first one with some little bugs and a second one with the needed corrections (see the "readme" file inside the zip for the explanations).

In any case I suggest to check at the Bill GitHub repository here for any update/information before sending it to a service (so you are sure to use the last updated version...).
