Kontrast - Public Domain
Kontrast, also known as "Series 7000" because it starts with disk number 7000 (!), was a short-lived public domain series from Germany. The series has no distinct features and is a seemingly random collection of programs released in other series. While only 50 disks were released, 15 of them are dedicated to TeX and various TeX printer drivers. Similar to other series created by German Atari dealers, quite a few disks are dedicated to clipart graphics and MIDI songs.
