StarTexter v5.2 was a well-known German-language word processor for the Commodore 64, published by Sybex and generally remembered as one of the stronger “serious” productivity programs on the machine. The StarTexter line began in 1985, the original C64 version was by Toni Schwaiger, and v5.2 is described by multiple retro-computing sources as the last major published version, with the 5.2 upgrade credited to Michael Möller.
