This event repeats every year forever
An ad for the Carina BBS software created by Jerry Horanoff appears on page 36 of the July 1986 issue of Antic magazine (Volume 5 Number 3). It retailed for $69.95, which included tax and shipping.
Prior to its general release, the BBS software was used by a few BBSs in Florida, according to the August 16, 1986 issue of Z*Magazine. An early version of the Carina BBS documentation lists a 1986 copyright date. The exact release date was probably sometime during the first half of 1986.
