	Nope...  A DX4-100 actually runs a tad faster than 100mHz
internally.  Exact, down-to-the-hertz, 3-to-1 synchronization between the
100mHz processor and 33mHz external motherboard bus is not necessary
because the DX4-100 has a 16K cache where the outgoing code can wait
until the next available motherboard 33mHz clock cycle.  So the 100mHz
CPU and motherboard are in fact running a bit asynchronously.

	That's because the CPU and motherboard both have their own clocks.
If the CPU and motherboard shared one clock then synchronization would be
important, as was in the days of the 286 and 8088.
