1984 CBS/Fox Hi-Fi VHS: This is fake stereo, but the kind that emphasises frequencies differently across both channels and that folds perfectly to mono. Excellent fidelity, especially quieter dialogue-centric scenes which reveal that the SE DVD does have some moderate hiss reduction. Unfortunately, louder moments lack detail compared to the SE DVD (indeed the entire track lacks a bit of dynamic range), and more pressingly there are strange volume fluctuations every 2-3 seconds in the capture I have.
1989 MGM LaserDisc [ML101565]: Okay, but globally lacking detail. More hiss reduction and bass attenuation than later editions, so it sounds a bit dead. Everything sounds thin. One segment of the film (~29 minutes in to the ~40 minute mark) is pitched 0.8 semitones higher than in later editions. I haven't formally checked whether this pitch is incorrect by comparing fragments of music from this section to the official score releases, but anecdotally I think Connery sounds off here.
1993 MGM LaserDisc [ML104539] - Connery Collection: Identical to the 1989 LaserDisc.
1993 MGM LaserDisc [NJEL-52730]: Like the 1989 and Connery Collection LaserDiscs.
2000 R1 MGM DVD - Special Edition: Superb. The best sounding Bond track of the first five films I've heard yet (was this the first Bond film with a magnetic mono track?). Less hiss and bass reduction than the LaserDiscs.
2006 R1 MGM DVD - Ultimate Edition: The SE DVD transfer but with noise reduction. After ~50 minutes in, the bass also rolls off significantly. Better than the LaserDiscs, but not nearly as detailed as the SE DVD.
2012 MGM Blu-ray: Like the SE DVD but with some additional distortion above 12 kHz, which I'd say is inaudible. There's a segment from 01:06:03 to 01:06:13 that has further noise reduction, but everything else sounds the same - which makes this the best of the mono Bond blu-ray tracks I've heard to date. NB: the 5.1 has loads of new sound effects and differently timed music cues.
Edit: On closer analysis, the additional distortion is frequently audible, albeit subtly. For example, at 00:03:01 ("Get back in"), there's some extra high-frequency noise that isn't present on the SE DVD, and again on the lines at 00:03:57.
