I purchased it a week or so ago, on behalf of a member of my family who remembers watching it in first-run.
So far, I have only been able to watch the bonus footage and the first two episodes (I've had a busy week), but I've already managed to find two surprises.
Surprise #1: There are eight episodes on the set, not seven. (The eighth is at the end of the bonus footage.)
Surprise #2: One of the episodes survives on b/w videotape, instead of the expected kinescope.
So, does anyone else have this, or is anyone interested in discussing this?
