Check that info on the password show with Bern Benett in the early 60s. I seem to recall that the pilot show was shot after 1965, the pilot show used either the Videograph or Divcon Graphics equipment. To narrow in on the date a little closer it was around the time of the first rendevous in space. T C Alred operated the graphics equipment at this time and his hire at CBS was 1965. If I would have to guess at a year, I would have to select 1967.
