Chekov, Sulu, and Mr. Scott
The guy on the right looks like Gene Rodenberry, but he's passed on, and the guy who played DeForrest Kelly who was the good doctor.
The blonde on the left is probably the nurse love interest for Dr. McCoy.
And the black woman is obviously the communications officer.
So, if you tell me he's Jerry Pournelle, I'll believe you. Except I haven't seen a picture of him in 20 years (in Byte), so I have no idea what he looks like now.
The REAL question, who is the Brunette? I can't seem to place her.
Someone in an earlier post said she was the computer voice, but I'd have to have audio to verify that. Affirmative.
