Targa 2000 RTX/Pinnacle Truevision, Stand Alone W/Documentation

This is a rare Targa 2000 RTX board mounted in the stand alone case with base, rack mount ears full documentation and software. It was working up until it was pulled but I cannot seem to locate to power supply so it is incomplete. I cannot find the power supply at this time and when I do it will sell separately. The power requirements are in the manual and it uses a DIN. It will be a simply 12 volt wall wort of about 3 amps but to be sure of the pins I would take the box apart and pin out the connectors and look at the board. This is a very, very heavy base and 19" mounts so the box weighs a lot.
