Yeah, as Danfun pointed out, the Star Trek TOS Blu-Rays have both versions of each episode: the unremastered originals and the "improved" remastered editions.

Personally, I prefer the original effects--in the majority of cases. But it's really nice to have both available. Wish I could say the same for Star Wars.

Oh, and the Season 3 Blu-Ray has a special bonus: the original cut of the second pilot, "Where No Man Has Gone Before." This has several pieces of alternate narration from Kirk, and very retro "bumpers" to reintroduce the show on coming back from commercial breaks, at the beginning of each new "act."

This version was actually believed lost for years and years--because Gene Roddenberry donated his personal copy to the Smithsonian, which promptly let it languish in a vault. Some collector in Germany found another copy and let CBS-Paramount use it as a source for a new release.

Now, that is interesting. Besides the Enterprise, there was another Trek exhibit I saw at the Air and Space Museum back in mid 70's. It was part of a larger display about Science Fiction and it's influence on real space travel. There was a 16mm film loop of the show playing, and it was the second pilot. (The loop was of the Enterprise entering the galaxy barrier.) I think a phaser was on display as well.

There was a similar installation nearby about the Flash Gordon and Buck Rogers serials.

The WNMHGB alternate cut is usually referred to as being Quinn/Martin Production style. Their shows popularized that format in the 60's and continued well into the 70's.
