Apple silicon supports the ancient Intel 8080 through a secret extensionStill supported nearly 50 years after releaseThe big picture: In 2020, Apple made the switch from Intel processors and started releasing Macs powered by its own custom chips.Apple went with the simplest but most effective method: emulating the x64 architecture within the Apple M1 itself.The ancient 8-bit microprocessor handled these adjustments and parity storages very specifically, and the feature has continued to find its way onto today's Intel processors.If you have a new Core i9-13900K, there is a direct (albeit minor) correlation to processors that powered some computers nearly 50 years ago.Bits 26 and 27 within ARM's flags register are dedicated to this process, though these two bits are only assigned to this action when Rosetta 2 is active."
