< Nope, no manuals except a copy of the N* DOS manual and a < monitor manual I believe. The system has a CPU board, disk < controller and a 64K RAM board so I'd guess N*DOS should load < fine. Opened it back up but don't see any DIPs near the back. < There are a couple of switchs outside the case which are labeled < for different baud rates for the video and printer port. The dips are on the mother board at the rear of the machine inside. They set up all of the IO charateristics including the sense of pins two and three in the serial connectors. I know of no Horizon that has switches for baud rates, that was a user mod. Allison
