I have inherited an ESA HPLC system that includes a 5200A coulochem Detector, 540 autosampler, ESA isocratic pump (same vintage) and the ESA 501 data system that has an ss tp420-rev b board that goes with the data system. This sytem anthough old in years has never been used. Unfortunately, we have no manuals for the data system and the ss tp 420 board. Does anyone have any idea of how to connect this system to the board and computer? Thanks
