Then I became more aware of Star Trek through the live action show and the Colorforms set (seriously). My next experience of TAS was the Viewmaster set of Yesteryear (around 1976). So I had that pretty well memorized.
Oh, man, I remember those Colorforms. Till now I had forgotten the Viewmaster set, but now I'm thinking yeah, I must have had that because I remember the bird guy scientist and I'Chaya entirely too well from that period!
I also remember my brother often pointing out that Spock's skin looked green in TAS while it didn't particularly in TOS.
