The instruction set of the Z80 in an extension of that of the Intel 8080. An entirely different set of assembly mnemonics is used. 8080 compatibility allowed the Z80 to be used in many CP/M systems, and this compatibility allowed CP/M to run on the ZX Spectrum +3, and a CP/M compatible system, Pro-DOS, to run on the SAM Coupé. | The instruction set of the Z80 in an extension of that of the [[Intel 8080]].

[[Zilog]] have released a number of variants of the Z80, and it has been second-sourced by many manufacturers, such as Mostek. In addition, there are numerous processors such as the R800 and T80 that are largely compatible with the Z80's instruction set. | [[Zilog]] have released a number of variants of the Z80, and it has been second-sourced by many manufacturers, such as Mostek.
