I find it interesting when someone makes foundational improvements when using an FPGA to mimic an old CPU.
The NextZ80 is a good example. It's designed to run 4x the amount of instructions at the same clock rate as a real Z80. And you can clock it to 40MHz, so it's effectively a 160Mhz Z80...compare to a typical 4/8Mhz real Z80.
