Anokon 1 was a Minnstf fallcon, held 22–24 September 1978.
Anokon 1 was originally intended to be called Minicon 14, in the tradition of calling all Minn-stf cons "Minicon", even when there was more than one in a year (see Minicons 5 and 9). According to Richard Tatge, the fallcon committee decided they wanted a different name from the springcon. As a result, Minicon 15 followed directly after Minicon 13, setting off 6 years of numerical silliness.
Rusty Hevelin and Bob Tucker were GoHs. (The program book doesn't make this very clear, but Greg Ketter, vice chair, says so. Also it appears in a mailing sent out to the RUNE list.)
Pre-reg was $4, at-the-door $7. Paid pre-reg was 63 people, and there were 57 at the door, so including the the GoH, the pre-reg total was 65 and the total 120.
Here's a PDF of the program book, which is made out of these images: 0 | 1 | 2 | 3 | 4 | 5 | 6.
Here are some higher resolution images, in case you're interested: 0 | 1 | 2 | 3 | 4 | 5 | 6.

The attributed text and all artwork is in the public domain due having been published between 1978 and March 1989 without a copyright notice or subsequent copyright registration. (At least this is how I interpret what happens under the fairly non-sensical "reversion" clause we used to put in publications.)
Here is a list found in a stack of Minicon stuff, of someone's attempt to tabulate Minicons. It is undated, but evidently was made during the period when Anokon 1 was known as "Minicon 14: Anokon", shown as a parallel case to "Minicon 12: The Dododecacon".
This list also nicely demonstrates that by 1978, it was already hard for people involved in Mnstf to reconstruct basic information about all the previous Minicons. (A RUNE of about the same period has similar difficulties.) What a difference the Internet makes!
