Sonderdisk - Public Domain
Special disks are a series of commercial programs which were distributed by Maxon Computer GmbH at a price of less than 100 Deutschmarks. Unlike the Special-Line-Disks of the Heim Verlag, the special disks were never published on CD. Whoever owns such a disk should archive it immediately. A database with descriptions and screenshots of the programs was published with the public domain database of Maxon.
