This event repeats every year forever
On or around this day, June 13th, in 1988, the Carina II BBS software is released according to an early review in the June 13, 1988 #110 issue of Z*Magazine. Another announcement for Carina II appeared on page 8 of the December 1988 #67 issue of Analog magazine. This BBS software, for the Atari XL/XE and written by Jerry Horanoff, is the sequel to the original Carina BBS software that was released around July, 1986. Carina II retailed for $65.00 (which included shipping and handling). For an additional $15.00, the buyer could also receive the popular RoboWars II online BBS game.
