The KC 85 ('KC' meaning "Kleincomputer", or "small computer") were models of microcomputers (KC 85/2, KC 85/3 and KC 85/4) built in East Germany by VEB Mikroelektronik "Wilhelm Pieck" Mühlhausen. The first model in the series, the HC 900, originally designed as a home computer and introduced in 1984, was renamed to KC 85/2 in 1985 to de-emphasize its use as consumer good.
Despite similar names, the KC 85 computers were not directly related to the KC 87 series produced by VEB Robotron-Meßelektronik "Otto Schön" Dresden.
The availability of the KC 85 series for private customers was very limited. The computers were mostly used at educational institutions, organizations, and enterprises.
