>Is the pin out on the dx50 the same as the dx33?

Yes, except that my public domain dx50 manual states that it has jtag
complient test pins.  For those and any other NCs which may not be NCs,
it would appear that leaving the pins alone makes it pin-compatible.

>Can you put a dx33 and slower clock into a dx50 motherboard?i

Yes, except you will be detuning the clock circuit which *may* cause
the machine to no longer be FCC/VDE complient... regardless, you would 
probably void any warentee.

>Isn't there a DX2, Overdrive ,whatever that has the same pinout as the dx33

The original intent was to sell the OverDrive(tm) direct and have an
OEM version, too.  The OverDrive(tm) went into the blue zip socket and 
the OEM version was for companies like Tandy who offer DX2 machines.  The
pinouts are slightly different.  There is a 169th pin along with slightly
different locations for other pins... telling you leaves me open for 
liability if you go and try to make modifications to your board.  You
can find the information yourself by finding the pinouts for the DX and 
the 487sx and comparing them.

>Hence the motherboard is not required to provided a 66Mhz clock signal?

This is true.
