I'm looking for any info on the Facit N1130 BTR. I own one that is missing the power supply. The chassis is marked 5VDC @ 1.3 amp, but the connector is a 5-pin DIN. There are at least two different circuits connected to the plug pins, so I suspect the power supply had 2 voltages. Operating instructions would also help. Any suggestions?

I located the documentation for the N1130 BTR. The previous owner of my unit was able to find it. After reading the manual, I learned that I might have to reload the exec file, which the previous owner does not have. Any help to locate a copy would be appreciated.
