From the project
As of right now this is revision 4. I know it could be improved very, very slightly by changing the position of key groups by less than a millimetre but I think it's complete now.

This PCB design was reverse-engineered from the original keyboard in an Amiga 1200. It is designed to connect to your Amiga 1200 with no modifications to the original machine, just take out the original keyboard and store it away safely. If you want an A600 keyboard, see my other repositories.
