The ZX Spectrum is more than just a nostalgic icon; it’s a masterclass in minimalist hardware design. At its core lies the – a custom chip that replaced dozens of standard TTL logic chips. This guide will walk you through the principles of designing a retro microcomputer like the Spectrum, focusing on the ULA’s role. You won’t be cloning a ULA (they’re long obsolete), but you will learn to replicate its functions using modern CPLDs, FPGAs, or discrete logic.
"If a function can be done in software, do it in software. If it saves a chip to do it in hardware, do it in the ULA."
