The 880 Processor
The 880 series of East German processors are clones of Zilog Z80 processors. The U880 and UB880 are Z80 clones, the UA880 is a Z80 A equivalent and the VB880 is a Z80 version with enhanced temperature range (-25 to +85 C) for industrial and military purposes. They were produced by Funkwerk Erfurt (FWE), later renamed to VEB Mikroelektronik "Karl Marx" in Erfurt (MME) in the 1980s.
 
The 880 CPUs were used in several GDR microcomputers like the RFT KC 85 series, the Robotron KC 87 and the Z 9001.
