The mechanical parts are common with the DX-32 control. What I am not sure is if the motors for the tool arm and the tool carrosel are 100VAC or 220Vac.
Are your drives Siemens?
The maintenance manual for this machine would also have all the schematics. It would be very valuable to get and it should have a parts section.
The 0M-Mate control is few and far between. Not very popular as it is was very tedious to use as you have to cursor all over the page to do what you want to do. Even i do not have any data on it nor the 412 that came with this control.
