Hi, I have the user- and servicemanual for the Datron 1281 in papperform, I might have the time to scan them later, are there any specific pages the you (M K) would like to start with? I have saved an 1281 from my former employer, who put it on the shelf when it died and they bought an Fluke 8508A instead. The 1281 is now working almost perfect after replacing all the electlytic caps on the digital board (to get it functional...), and then replacing the tantals on the Ohms board to get ohm working (there was a shorted tantal lowering the supply to an amp from 6.2 volt to 0.6V...) Now its only LoI that behaves a little odd in a few ranges. The 1281 is calibrated and run thrue all selttests an selfcal (calibrated against a Datron 4708) Please let me know if I can help you.
