The 486DX/2 chips .... are they *direct* replacements for the DX ?

So I hear all this stuff about the 486DX/2 being a direct replacement for 
the DX, and that any motherboard with a DX in it can support a DX/2 by 
simply replacing the chip. Well, I have a chance to get a 486DX/2 66 and I 
have a motherboard that only *explicitly* supports a DX 33. 

Do I need a special socket or can I 
just drop the DX/2 chip in in place of the DX ? Are they pin-compatible ? I 
really need to know because once I buy the chip I can't send it back and 
it's pretty expensive. Also, I have a 66.666 MHz x-tal in place ... do I 
have to change it ? 


Barring that, I may trade the DX/2 66 for a DX/33 and some cash, so if it 
won't work, I might still buy it and trade someone who *can* use it.

Let me know if you can help or if you would be interested in the chip if it 
won't work in my board.

Thanks,

-- Stephen
