Good questions but one very important detail left out. Is this a SX or DX?
Reason: The SX (if no one has messed with it) used a boot disk (floppy) to get the machine going. It did not have a herd drive.
The DX had a hard drive from which it would boot. The floppy was only a back-up of the machine software and not the full back-up. There was a small matter of a set of DOS 6.20 disks.
The only parameter file unique to easy machine was the SYS.BEZ file. This had the backlash comp values, machine travel (and pitch error comp for the ball screws on later machines). Easily copied if you are DOS literate, otherwise, there is a procedure to view them and write them down (if they exist in the first place).
Depending on the vintage of the machine, there may be updates. They are easy to install. All you need is a disk and an email addesss without a firewall. The disks are self extracting ZIP files which firewalls do not trust.
Will the machine boot right now? Are the CMOS correct? Are you or anyone at the facility PC/DOS literate? Do you know the version of software in the machine right now?
