Can you see the core mats or is there an opaque cover? I have some stuff
that may be the same thing you have (from an 11/05). Mine is marked
similarly, but three of the mats are blank.
I suspect that the same PCB could be used in several machines, including
an 18-bit machine w/parity, depending on how many mats were wired.
