Download the EAGLECAD files and build the board!...

I'll do a BOM soon, but the EAGLECAD contains the parts required.

Some parts are non essential if you don't want to put them in yet like the display or EPROm and SDcard etc. But you MUST do the Power supply and sockets and headers!

Note the numbered 40 pin double sided headers at the lower edge of the board provides for direct plug in to a 6" breadboard and the top header provides test points for clipping a logic analyzer , scope or multimeter for testing your I/O etc.
