I have this sl1 lather with a yasnac 2000g control. The problem is that our shop has all machines with a bit more modern controls that have a full crt and dnc serial ports for file upload. This one is a one line display, no crt. The previous owner had a computer hooked up to it with I believe a BTR. Not sure if we can figure out how to use this old of control or what to do with thus machine. Is there a way to add a crt or update it to where it is more conventional? Hate to scrap such a nice machine.
