I am tying to connect my old Gerber Hs15 Plotter to my XP pc, it was connected to my old Nec 386/25, but that pc died. It was running the old Gerber Advantage 3.5 solfware. I have most of the disk, but can't find all. The newer Graphic Advantage cost more that I can afford, so I was trying connect this Geber HS15 plotter to my New pc wiith XP on it. But can't find any drivers out here that will reconnize it, it connect to serial port. Anyone out here know anything about this that may help?
