The Zx Spectrum Ula- How To Design A Microcomputer -zx Design Retro Computer- (VERIFIED - Tips)

Use an Altera/Intel MAX V CPLD or Lattice LCMXO2 FPGA. Program it with ULA-like logic: video timing, contention, and I/O decoding.

Block diagram (conceptual)

Designing a microcomputer—whether a 1980s retro classic or a modern FPGA-based recreation—revolves around the delicate dance between the CPU and its supporting logic. This article explores how the ZX Spectrum ULA redefined hardware design and what it takes to recreate that magic today. 1. The Heart of the Machine: What is a ULA?

I/O Controller

is a definitive technical work by Chris Smith that reverse-engineers the custom chip at the heart of the Sinclair ZX Spectrum. Published in 2010, the book serves as both a historical record of 1980s engineering and a practical guide for hobbyists looking to design their own retro-style microcomputers.
