Looks like this is the "Brains" from an old Okuma OSP2200 controller.
Whether it is from a lathe or not, I could not tell you.
The photo showing all the switches is how you load the bootstrap program, tediuous and very annoying. You can actually read the fact that the board in the 4th photo is from the OSP2000 series of controller. I would guess that the LDU-200 (Linear Drive Unit) is from a later model machine.
