chip with the marking U880/6 had been developed in 1990 and went into production some time after that. The smaller chip allowed clock rates up to 8 MHz for the U880DC08 and Thesys Z80H. While Zilog likely could have taken up legal action against the successors of VEB Mikroelektronik "Karl Marx"

in 1990, neither project proceeded beyond pilot production. VEB Mikroelektronik "Karl Marx" (MME) was privatized in 1990 under the name ERMIC GmbH, a large part of which became Thesys
Gesellschaft für Mikroelektronik mbH in 1992. Both ERMIC and Thesys continued to manufacture the NMOS version of the

VEB Mikroelektronik "Karl Marx" also manufactured a number of support chips for the U880. The prefixes UA, UB, VB, 80, and 80A correspond to the same temperature ranges and clock rates as for the processor variants above. Likewise, the suffix S1 indicates the out-of-spec, hobbyist version.

Eastern Bloc. Examples are:

From about 1991 until 1993, bare U880 chips were sold to
Russian and Ukrainian companies and packaged there. Initially the U880/5 chip revision was labelled as 80A-CPU and
