The enclosed file srxtest.exe is a self extracting file which I downloaded from
the CYRIX tech BBS. It can be used to determine if your older (pre 1991) SX 16mhz
machine can be upgraded by the CYRIX SRX2 chip to an 486 32 mhz machine. 

That chip is currently available from CYRIX (800) 462-9749 for $202 thru the end
of February, money back guarantee. CompUSA is asking $250. The chip installs over
AN existing 386 processor chip (no need to resolder). CYRIX also has chips available
for higher speed 386 SX chips as well as DX chips*. According the to installation
documentation it is only the 16mhz pre 91 386SX chip that needs to be checked for
compatibility.

*A description of the DX chip is also included in the DX.txt file
