The animated series is set around the year 2269-2270 which is after the original series. Sometime prior to the events in the original series episode "The Enterprise Incident," the Romulans began to use warp capable warships of Klingon design. In the animated series the Romulans were seen using these type ships, as in "The Survivor" and "The Practical Joker". By 2269-2270, the Romulans probably still used the older design Birds of Prey but probably not in their encounters with the Federation's finest starships.

The series was available on eleven volumes of video tapes from Paramount Home Video beginning in 1995. They were priced around $11.00 for each two-episode tape and they can still be found used through Amazon.com.

The episodes were also available on a set of 6 laserdiscs that went for about $150.

Most recently, the entire set of Animated STAR TREK episodes were finally released on DVD on November 21st. The set is available for around $39 from Amazon.com.

But, in the STAR TREK universe, it is reasonable to assume that Chekov went away to receive further training to prepare him to return to the Enterprise as the ship's Security Chief, which he did in STAR TREK: The Motion Picture which takes place in 2271. This is only a conjecture based on the available facts.

 "The answer to the question is that in our universe, the faster you travel, the slower you age (as Einstein told us). In the reverse universe, the faster they travel, the faster they age--or in this case, grow younger. There was an explanation written into the original script, but of course the show is only 21 minutes long on the air, so quite a bit was cut."

Also, on page 13 of A.C. Crispin's 1988 novel "Time for Yesterday," Admiral Kirk made a reference to a Commander Arex.

M'Ress and Arex appeared in some late 1980's STAR TREK comics written by Peter David. They came on board with issue #37 (set right after STAR TREK IV) and stayed until #58. Some of these are collected in the graphic novel "Who killed Captain Kirk?"

M'Ress appeared and was named in the 1975 Peter Pan comic/record "Passage to Moauv" but was drawn to resemble an Orion woman. (See Picture)

• The Kahs-wan ordeal, which features prominently in "Yesteryear", was a ritual by which young Vulcan males proved their manhood by facing the dangers of the desert wilderness alone. An essentially similar ritual was described in the third season (1995) STAR TREK: Voyager episode "Displaced" (VGR) which was written by Lisa Klink. In that story, Tuvok stated that he took part in the ritual of tal'oth wherein as a young child he survived for four months in the Vulcan desert with a ritual blade as his only possession. It seems clear that script writer Lisa Klink paid homage to the animated STAR TREK series with this reference.
• In the animated episode "Yesteryear", Spock makes reference to the formidable range of mountains on Vulcan called Vulcan's Forge. Vulcan's Forge was also mentioned in the 6th season STAR TREK: Deep Space Nine episode "Change of Heart" (DS9). Vulcan's Forge is also the title of a STAR TREK novel published in 1998 by Pocket Books.
• In the November 1998 episode of STAR TREK: Deep Space Nine, "Once More Unto the Breach", Kor mentioned that he served aboard the Klothos, a D-5-class battle cruiser sometime when the Klingons were still the adversaries of the Federation. Kor, of course, commanded the Klothos in the animated episode "The Time Trap."
• In the 6th season STAR TREK: Deep Space Nine episode "Tears of the Prophets," the Miranda-class starship ShirKahr seen in one battle scene was named after the Vulcan city that was Spock's hometown as mentioned in "Yesteryear."
• Another reference to the Spock's hometown of ShiKahr was made in the February 2002 Enterprise episode "Fusion" when Tolaris, a visiting Vulcan man, said "I taught literature at the ShiKahr Academy."
• Lastly, Holodeck technology, which became a major fixture in all subsequent STAR TREK series and which was the center of several storylines in the next three series, was introduced in the 1974 Animated STAR TREK episode "The Practical Joker."

In the episode "The Counter-Clock Incident" it was stated that April was made a Federation ambassador-at-large twenty years before the episode, which places it in 2250. That was the same year that he relinquished command of the Enterprise to Captain Christopher Pike. So in my Timeline page, I put his promotion to commodore in the same year.

• Galileo-type Shuttlecraft.
• Aquashuttle.
• Heavy Shuttlecraft.
• Copernicus-type Long-Range shuttlecraft.
• Scouter-Gig.
• Small Federation Scout*

*The scout was the small ship with a rounded foresection visible at the extreme right of the Enterprise's expansive hanger deck interior in scenes from the episodes "Once Upon a Planet" and "Mudd's Passion." The scout ship (pictured) was a new ship that was designed for the animated series but never used in any episode.

• "More Tribble, More Troubles" written by David Gerrold was based on a script he had originally written as a possible third-season Original STAR TREK episode.
• "Bem" written by David Gerrold was also based on a script he had originally written as a possible third-season Original STAR TREK episode.
• "The Time Trap" written by Joyce Perry was perhaps based on an August 1972 issue #15 of the Gold Key STAR TREK comic series which was published a little more than a year before the Animated STAR TREK episode aired.
• "The Slaver Weapon" written by Larry Niven was adapted from his 1967 short story "The Soft Weapon."

6. Robert Wesley, former Starfleet commodore turned governor, appeared in "One of Our Planets is Missing" voiced by James Doohan, after having appeared in "The Ultimate Computer" (TOS) portrayed by Barry Russo.

Production numbers are akin to check numbers in a checkbook - a skipped check does not necessarily mean one was written and lost, but perhaps it was simply VOIDED. Television series production numbers are assigned months in advance of production so that actor schedules, scripts, sets, location visits, billing and credits can be coordinated with the correct episode. This is necessary because during production of a series several episodes are commonly in different stages of production at the same time. For example: Episode #05 may be being finally editted, Episode #06 could be before the cameras, Episode #07 could be having voices recorded, Episode #08 could be in drawing/cel painting stage, Episode #09's script could be in pre-visualization/background creation mode. At the same time, Episode #10, #11, #12 and #14 would be in script writing phase with Episode #13 perhaps being dropped due to a writer's schedule unavailability or some other reason. During production, there are times when scripts are put before the cameras or voiced earlier or later than expected for reasons of scheduling conflicts. This would perhaps cause Episode #14 to be voiced (and subsequently finished and aired) before Episode #10. Missing production numbers are not like missing murder investigation evidence. They are simply reference numbers used by management.

Filmation was the first studio to add a moral in the form of an epilogue at the end of animated television episodes. In an interview for Agent DVD Online, Filmation co-founder Lou Scheimer said, "The PSAs were always about the moral in the show, literally to help the child with the concept of the lesson. The idea started with Bill Cosby doing the live-action segments on Fat Albert. It was very effective. We had these superhero shows and at the end the hero would talk about what was in the episode. It created really good will. Mothers were writing in. It was very successful for the kid audience."

The reason that episode-specific PSA's were never made for the animated STAR TREK series was because it did not feature physical violence which might require a special moral in the form of lesson-giving epilogues to provide balance.

The actual PSA and several that I created can be found on the STAR TREK Public Service Announcement page.

  I don't know. Don Christianson, the show's art director, had a hand in most of what the audience saw on the screen, but I can't say for sure who designed any particular characters. As for who came up with the idea for Arex and M'Ress, it was probably D. C. Fontana or Gene Roddenberry, but again, I may very well be wrong. I will look into this further.
