Just recently acquired a Data I/O 3980 programmer in a not working condition and have determined that the open frame power supply made by Power One MAP80-1012 is dead. I located a replacement NOS Power One MAP80-1012 supply on ebay and would like to complete the re-installation. This power supply output is variable from 10V to 15V. Does anybody know the exact set-point output voltage value required by the 3980 for this power supply? I do not have a service manual for this beast. Does anyone have a scanned copy or original service manual for the Data I/O 3900/3910/3980 programmer series?
