The Zilog Z80, which debuted in July 1976, has been a cornerstone of computing for decades. With 8,500 transistors built on a 4μm process, it was a revolutionary chip for its time, typically running at a clock speed of 2.5 MHz.
As we celebrate its 50th anniversary, the Z80's legacy continues with the announcement of an open-source replacement designed to fit into the traditional DIP40 package. This new silicon aims to provide enthusiasts and developers with a modern alternative while honoring the original architecture.
Despite being discontinued in 2024, the Z80 remains a beloved component in retro computing circles, and this new development is expected to breathe fresh life into projects that rely on its unique capabilities.
