First 24 hours per day Atari BBS

In February 1982, the Michigan Atari Computer Enthusiasts (MACE) start the first Atari BBS that would operate 24 hours per day. They would use their own Atari Message and Information System (A.M.I.S.) BBS software. The BBS software ran on a 48K Atari 800 with a Hayes Smartmodem, an Atari 850 interface, four floppy disk drives, and an Atari 822 printer (source: The Atari 8-bit Frequently Asked Questions by Michael Current).  The MACE BBS is mentioned on Page 44 of the June 1982 (Voume 1 number 2) issue of Antic.
