What is on Your Mind?

Not Barbara Eden. Here is a second photo. I want to find photos that have her in character, because that's the only way people will recognize her. (Not counting hardcore fans.) But most "in character" photos give away too much.

A few hints... The show was on ABC until it was canceled in 1971. All 1225 episodes are on DVD and the entire series has been shown on Sci-Fi several times.

Easy to google the answer with that BIG clue

Don't count your chickens yet, Neo. Go back and look at the clues I dropped for Mr Wizard. Dave Letterman had three guests on his first show and I believe the photos I posted should allow folks to eliminate Marie O'Donnell. Now it's either Bill Murray or Don Herbert. Several other clues should have converged on the answer just as quickly, but still no one got it. Go figure.

We lost a few posts in this thread. Yesterday zazzybob correctly guessed that the actress is Lara Parker. ZB, please repost your photo.

Here's the picture (bigger this time).

I'll give it 24 hours then provide some hints if required

Cheers

OK - a fairly big hint here - a Linux kernel maintainer past or present.
