Same problem, the link to the PCB layout (on bottom of webpage) doesn't work.

I can make a Gerber PCB layout (or JPG, PDF) if you want.

Could you make the PCB the size of a Z80 CPU (40 pin DIP), so it can sit on top of the processor like was done with the first versions of the 7mhz clock upgrade. This means also SMD components for IC2 and IC3 (but thats no problem).

I wonder if instead of putting it on top of the Z80 one could design the print to sit between the socket and the Z80?

Sure, if you send me the schematic, I'll give it a go over the coming days...

That should be no problem, did it with an Atari 2600 also.
But the best solution for doing something like this is to have it shifted a bit, so they are not directly above each other in order to have a bit of room to solder some pins in place.
