I first viewed this episode three years ago while living in Los Angeles. I haven't seem it since, but the computer themes of this episode have stuck with me. I don't remember the entire plot, but a so-called "computer consultant," as stated on the killers business card, uses computer technology as part of his criminal activity. He also strangles his victims.
What seems to stand out most of this episode, filmed in 1974, is the pervasive use of advanced computer technology, for the day. He uses what I've researched to be an ADDS Envoy portable computer "dumb" terminal and a car mobile phone to break into the Hawaii Motor Vehicle Dept. Remember, this is almost ten years prior to the movie Wargames. He seems to also use a computer terminal from his home with the old phone receiver-pickup modems.
An episode that is well ahead of its time in using portable computer equipment and early car mobile phone system.
Really a very cool episode and would love to find out how the writer came up with the computer themes.
