The Black Cats was a French Atari ST demo-group founded in October 1984.
In 1985 there were five members: Doc Prof aka Mr Jean, Sharp Man, JPMaster, MicroPat and TrackMan. They all bought different 8bit machines except for TrackMan who left the group. Their attention came to the recently released Atari ST. MicroPat moved and they lost contact.
In 1986 a new member called The Fox joins the group who is the first guy who owns an Atari 520 STf. The Fox sold his machine to Sharpman and Doc Prof and JPMaster bought Atari ST machines too.
In 1987 Sharpman and Doc Prof started to learn machine language and JPMaster became a graphician. JPMaster buys and Amiga and leaves the Black Cats.
