Hello I'm new here

I just Bought an old Boxford 280 TCL, CNC Lathe.

It's controlled with an OLD PC (using floppy discs, and running operating system: DOS- since its OLD)

The PC is connected with a DB44 connection (looks like a standard parallel port but has 44 pins)


My Questions:
1 Does anyone know if I can connect another (more designated) kind of "control box" instead of a PC -just using the DB44 connection (more or less) ?
2 Does anyone have any suggestions for how to get a more "up to date" kind of controlling (still using ISO G/M programming)

- I want to be able to use CAD/CAM (But I guess that's "only" a matter of the right Post Processor?)
- I'm working on a tool turret instead of the gang and on a C-axis.
3 is this ^ only a matte of the "Controller" or do I need the replace/ change the electronics on the lathe itself?

I hope I'm not asking too much, and if You could answer just one or some of the questions or give me some pointers I would Greatly appreciate it!

I'm use to programming CNC lathes and Mill's but i'm pretty new to the electronics and the machines themselfs
