The Zx Spectrum Ula How To Design A Microcomputer Zx Design Retro Computer Portable ((exclusive)) -
“The ULA is the heart – we put it in your hands. Build, code, clash, and carry the 8-bit revolution.”
For a modern retro-build or portable device, you can replace the original ULA using these methods: ZX MAX 128 ZX Spectrum Clone Build “The ULA is the heart – we put it in your hands
" by Chris Smith is the definitive guide. It contains over 140 illustrations and reverse-engineered circuit diagrams. Most modern recreations (like the ZX Spectrum Next)
Most modern recreations (like the ZX Spectrum Next) use an FPGA (Field Programmable Gate Array) to "clone" the ULA’s logic at the hardware level. This allows for 100% accuracy and the ability to add "enhanced" ULA modes (more colors, higher resolution). : The Raspberry Pi Pico Go to product
For a simpler, more portable build, use a powerful microcontroller to emulate the hardware in software. : The Raspberry Pi Pico Go to product viewer dialog for this item.
When designing a modern "retro" microcomputer or a portable handheld, you have three primary paths to replicate or replace the original ULA: 1. The FPGA Approach Modern implementations like the ZX Spectrum Next Field-Programmable Gate Arrays (FPGAs) to recreate the ULA's logic. Advantages:
