>>Get acquainted with the system is a good thing to do if it's possible, right?
Well.. if you can get it to run and do what you want to do with the existing controls, that is fine. But if I were you I would use that opportunity to understand how the turret works, electrically and mechanically, how the drives function, how the machine is shifted - if it has various ranges, etc and then line up some parts and time to retrofit that machine. Assuming you keep the drives, I would start looking for spares to keep on the shelf. The problem is that when that machine goes down hard, it will be very difficult and expensive to get it to run again, unless you have a cache of spare boards. So if you take an order to run on that machine for a 1000 parts and you are 200 parts into that order and the machine dies, you may be in a very bad spot.
