I have a working set of TMA1-03 video and cpu boards from a Mario bros. I also have a non-working set of TMA1-02 video and cpu boards from a Mario bros. I would like to swap boards (I.E. use a 03 video, and 02 cpu) to help narrow down the problem with the non-working boards. Will this be an issue? Are they compatible? They look very similar/the same.
