After battling the 64 bit OS issues I decided to take the computer back to the seller. I retasked my 6 year old XP 32 bit machine to run my plasma/router. I pulled the ports from the dead machine and installed into the old machine with XP sp3. Installed Mach, ran the driver test and got a "excellent".

Now I was going to feed my old xml files in and I noticed the two port addresses are different looking. The old addresses were a hex address xab0 or something like that, the new are 9400 and 9800. I double checked using the "Get port address" file in Mach. I haven't hooked it to the CNC machine yet. Does that sound right or does XP SP3 do something different with addresses?
Thanks Much,
Mike
