Alfred, Thanks for your reply.Yeah I would highly appreciate if you can send me manual for LC-8A; maybe I can use some details from that into my current pump. The good thing about equipment from 1980s/1990s is that the manuals from that era contained much more detailed descriptions about the electronics and communication protocols/pinouts etc compared to modern manuals for agilent 1100/1200 which are very descriptive and user friendly, but has serious gaps with describing the actual electronics behind their equipment.
