I was born in '65, so I had that transporter playset that the OP mentions. You spun the doll around and it looked like it disappeared. I had the large dolls of Kirk, Spock, McCoy, Scotty, Uhura, the Gorn and a Klingon. I may have had other aliens, but I don't remember quite. I bought all the models that I could - I was a model nut. At one point I had all the original James Blish novelizations of the TV show. I still have some of the micromachines, which I got later in life. I wasn't quick enough to get them all.
