(Why do we think we know the dates? Maybe because of a 1-page mailer in the archives — should check that.)
Gordon R. Dickson was GoH. Warren Cartwright chaired it.
Suspected from jotted notes and hazy recollections to either have been at the Kelly Inn or the Holiday Inn Capitol. Definitely in St. Paul. More likely at the Holiday Inn Capitol, since that's where Not-Anokon 2 was.
Here are two Not-Anokon badges that don't say what year they are. There have been four Not-Anokons and we have badges for 2 and '85, so these must be for 1 and 8, but we don't know which is which.
This program, uh, pamphlet, I guess (it's two sheets with one staple, so not a book, not a booklet, but not just a sheet either) is untitled and undated, but given who the chair is and the fact that it doesn't give "Not-Anokon" a number strongly suggests it's for Not-Anokon 1. It also lists a Shockwave show on Saturday, which matches the one below, although I guess it's possible there was also a Shockwave show on Saturday of Not-Anokon 2. The University of Iowa has a copy of this, and they have it cataloged as from Not-Anokon 2. I asked them why, and they said that it's in a folder that says "NotAnoCon 2, St. Paul, Minneapolis, 1981" and that's all they know. I still think it's more likely from Not-Anokon 1.
Similar comments apply to this restaurant guide, which came with the program pamphlet in the University of Iowa collection. It clearly indicates that the hotel is the Holiday Inn, so if we believe which con it is, then we know what hotel it is.
The radio show Shockwave was recorded at Not-Anokon 1. Here's some audio.
