The Zx Spectrum Ula- How To Design A Microcomputer -zx Design Retro Computer- | 360p |

In the early 1980s, before the prevalence of CPLDs and FPGAs, the was a revolutionary technology. It consisted of a pre-manufactured silicon die with a sea of uncommitted logic gates. A customer like Sinclair would provide a final "mask" to define the interconnections between these gates, resulting in a custom integrated circuit at a fraction of the cost of a full-custom design.

The 4116 DRAM chips (16Kb) used in the Spectrum are lazy. They forget data every 2ms and need a refresh. They also cannot be read and written at the same time. In the early 1980s, before the prevalence of

To ask "how to design a microcomputer" in 2024, you do not need a ULA. You can buy a $2 microcontroller that runs circles around the Spectrum. Core Functions of the ZX Spectrum ULA The
