NAND now back at full speed. (measured at about 10 x faster on the 'scope).
NAND_RNB needed a pull up, clearly we are now reading this in the NAND
(Note this is not a "real" resistor but a programmed one inside the FPGA).
The CPLD .ucf file had one but the FPGA .ucf file did not.
I'll check stuff in on Monday now...
