If you don't have this working before the weekend let me know and I'll
pull a Tempest spinner from my cabinet and tinker with it some. The
2.2K resistors on the replacement spinner board might be too much. (Is
that what you mean by "main board"?)

IF the Tempest spinner is actually outputting CLK and DIR though, you'll
need to take a couple taps off directly from the quadrature outputs.
The Sega Board is expecting quadrature inputs, not CLK and DIR.
