I have a new theory about the history of this set. The modifications are very unprofessional, with cold solder joints and midair connections. I can't believe that RCA engineers would do that kind of work. I think the set was abandoned by RCA after its life as a CPA prototype, and the later mods were done by someone who got the chassis, probably an attempt to make it work with NTSC.

Steve,
So then you will be restoring this as a CPA set? If so is there any chance that at least the sweep and decoder sections could be working by the convention? I can get started on developing a CPA converter.
BTW does anyone have the actual spec for CPA? Can we assume that most things just match NTSC (burst length, phase and position) and only the R-Y inverted every other frame?
