I have two Excello's I retrofitted with the Acroloop 8000.
If you test ran the machine, then it should have the software on it. Is it the DOS version or NT?
The Software used to be available, but since Acroloop was taken over by Parker they supply Win XP MotionMax s/w for alot higher price.
You can usually get the s/w onto one floppy if it is DOS, I can tell you the directory to back up if so.
I would be interested in what version you have and would like to see if that version has the couple of bugs that mine has.
If it is fitted with a VFD then most will run on 220 1ph or off a 3PH RPC.
Make sure the 2 main legs of the supply feeds the 220v control transformer side.
