Here is two versions of CNC Pro.(I hope not the very last 2).
The one from 1-21-03 is faster, but could have keyboard problems.
You can run it on a slower computer.

The 4-18-03 is the last version, posted on Yeager Automation's site
before it went down.

We have a 60 inch by 120 inch travel router with a 12 HP spindle
that is controlled with CNC-PRO. I even have a small Lathe
that uses it also. 
The picture is of the router's control panel, that I made.
All the tags for the buttons were engraved on the machine itself.
