Sort of kicking it old school. Timing will be fun, there is a notion of 'lumped' versus not lumped circuits (and this is especially true of logic) where you want the entire circuit to fit within one wavelength of the fastest clock (where that is determined by the speed of light) otherwise you end up with really hard to debug timing skew problems. At 9 meters your CPU will be challenged to run at > 33 Khz but you will be able to do better than that with good layout and floor planning.
Quite the project, I look forward to the final report.
