		VEB Mikroelektronik „Karl Marx“ Erfurt, prior to 1983 labeled the VEB Funkwerk Erfurt, was a people-owned enterprise (Volkseigener Betrieb, VEB) manufacturing microelectronics and semiconductor devices, located in Erfurt, East Germany at that time [1] [2], and head of the correspondent VEB Kombinat Mikroelektronik „Karl Marx“ Erfurt combine producing under the trademark Rundfunk- und Fernmelde-Technik (RFT) [3]. Funkwerk Erfurt emerged from a former Telefunken facility during the Socialization in East Germany in 1948. After the Wende in 1990 it successively evolved to the X-FAB Silicon Foundries.

Chess Computers

In the 80s VEB Funkwerk Erfurt and VEB Mikroelektronik Erfurt manufactured various dedicated chess computers based on their own produced Z80 clone U880 ^{[5] [6]}, notably the SC 1 and SC 2, which in turn were clones ^[7] of Ron Nelson's Chess Challenger programs, manufactured by Fidelity Electronics, and since 1983/84 the Chess-Master models with programs written by Dieter Schultze, Rüdiger Worbs and Wolfgang Pähtz.
