The U880 is an 8-bit microprocessor that was manufactured by VEB Mikroelektronik "Karl Marx" Erfurt in the German Democratic Republic. Production of the U880 started in 1980 at VEB Funkwerk Erfurt. The U880 is an unlicensed clone of the Zilog Z80 microprocessor, also supporting illegal opcodes and bugs, except for very minor differences like not setting the CY flag for the OUTI command.
