I've done a version based on Tony's design. I'm about to send the board
out to be fab'd. I've sized it so that it should be able to take the
original overlays too.

I'll be offering the PCB's (with schematic, BOM, etc) or PCB + parts +
docs for sale once I get the first boards back and debugged.

The PCBs will be nice with silk screen, solder mask and gold edge
