Does anyone have a busted A40 TCM that they could take a picture of the PCB and tell me exactly what CPU it has?

I've been tempted to look inside, but given the size of the case I would suggest there will be nothing to see. It will be a ceramic PCB with just the chip dies. Much like the T42 TCM is.
The A40 is using a PowerPC MPC555, actually I don't know the exact CPU version, 555, 561, 565 etc, but it's from that family.

Cheers,
Ross

Would a ceramic board be green? I haven't seen one myself, but I asked a friend who has one with a hole in it, and he said he was pretty sure it was green with a clear epoxy/resin coating it, like I've seen in Ford PCMs.
