C= never maded a single 1200 with FPU, nor RTC...
They came close, though. The manual says the FPU is a factory-installed option.

Yeah, the Flash memory part looks interesting... but it seems like the traces for it never made it into the PCB layout. I wonder if that module was supposed to connect to the "complete" dual-44-pin clockport headers. There was also supposed to be a 1MB version board with the second meg of Chip RAM connecting there... maybe the Flash was part of that module.
If you have the full header on P9B, your board is probably much older than 1D4. I have a 1D1 that still only has the clockport pins rather than the full headers.
A full service manual would help, I think. I've never seen one for a 1200, but the 3000T version has a complete list of all components.
