The haul also included an ADM-3A terminal (always wanted one of these), and a dual 5 1/4" floppy cabinet (don't know which system this goes to). I got no documentation, no software or anything (these were all picked up from a curb-side garbage pile!!)! I've always admired the ohio scientific systems...and almost bought a C1P back in the late 70's (it was a toss up between a C1P and a trs-80). Any pointers to documentation, software, specifications, etc?? I have 5 C1P models including a plastic case one. I have schematics and shiny advertisements that must have came with the system. Interesting machines although I have not tested mine yet. The 4 I got last year have all sorts of switches and knobs on them. I think they were modded for extra video capabilities.
