Atarisoft

Atarisoft was the software publishing label of the original Atari Corporation, primarily used to publish personal computer versions of popular arcade games (both Atari and non-Atari).

The advertising blurb for most Atarisoft games read as follows:

The world's most popular video games can be yours to play at home, now that Atari makes them for the IBM PC. And the possibilities don't stop there. More compatible software will be available soon from ATARISOFT, including educational, management, and productivity programs.
