What's the deal with the "CPU board" exemption?
Where is there such an exemption?

So if one sells a board that has say a PIC on it and some support logic,
and the 9kHz+ signals are all internal to the uP (self-clock), but it's
otherwise a functionally complete design other than it's not in a
housing, is that an exempt product?
