*Doh!* Another one! ;-) Does the Mad Planets gizmo have a "decoder" PCB
that the spinner talks to? (Or do the quadrature outputs go straight to
the PCB?)

Yeah, I can use a couple jumpers on the board and physically "reverse" the
connections. (Or, can you just invert the signals? Or maybe you invert
one line? I'll have to think about that.)
The other option is to go to a 28pin PIC with another 8 bits of I/O and do
everything in firmware.
