== UA880 CPU (equivalent to Zilog Z80) ==
The KC compact uses a UA880 CPU, which is a Russian an East German clone of the [[Z80]]. It is not confirmed whether there are any actual differences compared to a real Z80. In terms of documentation, the KC Compact System Handbook lists the opcodes SLL, INF [a.k.a. IN F,(C)], and OUTF [a.k.a. OUT (C),F], whereas these have remained undocumented by Zilog.
