The ZX Spectrum ULA: Designing a Modern Portable Microcomputer

For beginners, an RP2040-based emulated version is faster to prototype. But for the true “design a microcomputer” experience—understanding contention, video timing, and memory arbitration—an FPGA ULA is the definitive modern method. The ZX Spectrum ULA: Designing a Modern Portable

The ZX Spectrum's design offers valuable lessons for those interested in creating their own microcomputers. Here are a few takeaways: Here are a few takeaways: Because an entire

Because an entire 8×8 block shares just one Ink color and one Paper color, moving sprites cause colors to spill into adjacent blocks. This is . Embracing or perfectly simulating this limitation is vital for an authentic retro microcomputer design. Designing a Modern Portable ZX Spectrum Designing a Modern Portable ZX Spectrum By mastering

By mastering the fundamentals of the uncommitted logic array and adapting those tightly integrated timing patterns to modern components, you can successfully resurrect the magic of 1980s computing in a pocket-sized, travel-ready design. If you want to start prototyping this project, let me know:
