Without reading back the whole thread, are the pre-86 video releases represented?
msycamore did show a pan/scan shield generator shot . . . from what source?

IIRC some of dark_jedi's p/s preservations were posted on usenet in the recent past, but those were the time-compressed LDs. I know nothing about time compression, but I'd guess they'd be missing some frames or fields (or have some blended together) which might or might not be a problem if you're looking for specific frames.
I think I'll repost dark_jedi's "Standard Play" preservations. Those are the uncompressed pan/scan CAV LD sets 1130-84 & 1425-84 (the same ones believed to contain theatrical soundtracks, since they predate the digital sound era.)
