The Poolware disks, also known as the P series, is a series from Germany that starts with disk number 2000. Created and curated by various Atari dealers, Poolware doesn’t have a specific focus, covering both games and applications. The series was advertised with full-page ads in German Atari magazines with the cost split between the participating dealers. The dealers also sold the magazine PD Szene. With the disk 2331 the business model of the Pool series changed: The disks now cost 10 instead of 8 DM, for which a 20 percent royalty was paid per disk sold. A condition was exclusivity to the Pool series. Usually such programs contain a note that distribution via other commercial series is prohibited.
