The EditDroid DVD did not use the 1993 mix. Just listen to it. Note that it has the tractor beam line! Therefore, it's safe to say that the EditDroid disc uses the 1985 mix, since that is the only home video release (prior to the SE) to have that line. I recall a thread here where I pointed this out to the creator of that disc and he admitted he didn't realize that the audio he used wasn't the original track, though it is the track closest to the original.

If anyone wants the original 1977 Dolby Stereo mix, I have an Apple Lossless file of it, taken from the 1983 CAV pan-and-scan LD.
