You'll have to sort out your own files, but I can provide a link to an older page by Leon Borre that describes the process.  You can skip everything about making and modifying the circuit, my adapter takes care of all that, you just need to sort out how to get the data onto the EPROM.

Now, here's the other important bit.  Williams was very inconsistant about the components they used on their CPU boards.  For some reason, this adapter simply won't work on about 10% of the boards it's installed in, even if the CPU board is perfectly fine.  I don't know the exact cause yet, so the best I can do right now is inform you this may happen, and be very very lenient with the return policy.   So I am allowing 2 years for returns on these PCB's,  minus shipping of course.
