I saw some flap on the WOF boards, that anything pre 1985(save for the episode we know are there, like Pat's first show, Chuck's last show, first nighttime, etc.) is probably gone. Anything after 1985 is still there. There was also Pat's last daytime show during the marathon also. Basically, not all of them are gone. I bet it's a case of "Peter Marshall Hollywood Squares" all over again. They thought all of those were gone, and found about 200.

But that's a lot less than all of them, which you're willing to believe is there just being hidden.
Pre-1985, I figure, is kinda pushing it, though. Unless NBC was still wiping shows after 1981, because we know Go's intact and the G-T shows that were there are as well (except for Mindreaders and even though G-T was good with that), I highly doubt '85 would be the earliest you could find episodes from. (I would figure maybe two years earlier than that, for reasons I'm not entirely sure of, but I would figure if the practice as a whole had ended by the early '80s that episodes from some point before '85 are still around, but not too far of a point.)
