Many issues...

And you can't just fit in a standard PC power supply...

Yes, it was standard and it's missing.

No memory, no memory controller, nothing...

Of the three 1000F I have all have their firmware in slot 10 on a FAB 
because the mainboard simply doesn't have enough sockets for all the ROMs.

Doesn't hurt.

All 8 channel muxes have these edge card connections.

Not sure whether it's the controller for the 7970B or 7970E.

These are simple digital I/O boards. But thanks to DCPC any board supports 
DMA :-)

Same as in slot 13.

Well, it isn't an F series. An F series consists of the proper firmware 
ROMs (SIS, VIS, FFP, FPP) and the external FP processor, but everything's 
missing. You could plug in the firmware from an E series, and then it's a 
My machine here also has the RTE6 and SIGNAL/1000 firmware ROMs.

I think it's complete, but the cables are missing (especially the 
connection from the FPP to the MPP on the CPU front panel).
