Is it possible to speed up an old 6Mhz IBM-AT (not a compatible) to 12Mhz
by changing the crystal in it?

We have an 80287/6Mhz and 512K RAM+1128K AST Rampage card in it. I think, the 
RAM chips have a speed of 120ns.  Would changing the crystal create any problem
with using these?  Do I have to change the '287 and the RAM chips also?  Do I
have to change the '286 chip itself?

I would appreciate any advice from the netters.

Thanks,

Baskaran.
