Has anyone come across a GE Mark Century 2000 PLC or the software program it? We have come across a CNC that is using one of these and come like to modify it.
When GE got into the joint venture with Fanuc, they stopped selling the Mark Century 2000 line. That was in 1986. That makes your unit at least 19 years old. It might have been programmed with a dedicated programmer rather than a DOS software package.
