Zilog Z80 marks 50 years after shaping early PCs, embedded systems, CP/M software, and Game Boy-era chip designs

The article looks back at the Zilog Z80, launched in July 1976, and its outsized role in 8-bit computers, hobby systems, and industrial equipment. Its compatibility with Intel’s 8080 family helped support de facto standards like CP/M and Microsoft BASIC, while derivatives and clones influenced devices including the original Game Boy.

The Z80’s longevity shows how simple, well-supported architectures can persist for decades in embedded systems long after consumer markets move on. Its history also highlights how compatibility and software ecosystems can matter as much as raw performance in determining a chip’s legacy.
