No difference in the mobo, per se.

For the /200 case, the processor is run at 200 MHz and the bus is run at 
50 MHz (full speed), using a 4 multiplier ... 6 with respect to the PCI 
cards, which are run at 33.33 MHz (also full speed).

For the /180 case, the processor is run at 180 MHz and the bus is run at 
45 MHz, using a 4 multiplier ... 5.5 with respect to the PCI cards, which 
are run at 32.72 MHz.

The processor, cache, bus and PCI cards must always be run at an integral 
or half-integral multilier of each other.
