HEY, Loving Emc.. I have still not got it to run on my cnc mill. XP
pro and Mach3 crashed.

I designated EMC to the trash pile a long time ago, after trying to load it for hours and multiple times.  I have one Dos 6.22 computer in the shop, with the Xylotex drives and fan mounted on the bottom, and the switching power supply mounted in the top most drive bay.  Seems to work well with TCNC.  

However when I looked at the latest version of Mach, V1.84 everything else went out of the window....

 

My condolences for your Father.
