to handle the logic usually reserved for the ULA, simplifying the build for those who want to use a real Z80 but avoid complex gate arrays. Portable Design Considerations
When you build a using an FPGA replicating the ULA, you are not just copying a circuit. You are reincarnating a philosophy: How much can one chip do? You become intimate with the Z80’s timing diagrams, the agony of the 4us refresh window, and the joy of a crisp, 8x8 attribute clash.
