I am mostly interested in finding all these items good homes where someone will use them. I get a bit nostalgic about these like I do about arcade games. I have a small interest in maybe building a projector with the Omnichrome, HeNe, and PCAOM however I think I just want to use the projectors I have and not have to tinker with these items. What do you all think? Is there anyone interested in these items? I did see that DZ recently came into possession of Lowell Cross's projector with a similar laser. Does it need a newer (probably) working laser?
