This page is in progress. The part list is incomplete, but I've managed to list the two ICs that are trickiest to find. It doesn't use the Z1FFER shield circuit, but operates on the same principle, and like the shield, it's based on a design from Bill Cox. Here is Bill's original schematic. The only difference is that I've found equivalent components that can be mounted in a breadboard.
