RE: Upgrading an AS/200 4/233 cpu??

["Hoover, Tony" <hoover sal ksu edu>]

I don't have an AS200, just a little info.
The 21064 is not pin compatible with the 21164.  The fastest 21064 is 300
Mhz.  Also remember you will have to figure out how to adjust the clock
divisor so that PCI and the memory bus run at the correct speed.

Good luck.
