Digital Press: Maybe you could use the screenshots for Amazing Snake, since they might be from the programmer?
newcoleco: You programmed a version of Reversi for the ColecoVision? It looks as good as the one for the NES!
Unfortunately, the Star Trek screenshots still don't indicate whether or not the CV version has all 6 of the screens (meteor/comet/dock-with-as-many-Starbases-as-possible screens).
