Open-Source Silicon Replacement Developed for 50-Year-Old Zilog Z80 CPU

The Zilog Z80 CPU, a classic 8-bit processor, has reached its 50th anniversary. To mark the occasion, an open-source silicon replacement is being developed, designed to be a drop-in component. This initiative is particularly relevant for retro computing enthusiasts and could also serve niche embedded systems by providing a modern, open-source alternative to the original chip.
