Published in 2010, this 300+ page work is the result of a complete, transistor-level reverse-engineering of the Sinclair ZX Spectrum’s heart: the Ferranti ULA (Uncommitted Logic Array). More than just a history, it serves as a practical masterclass in 8-bit computer design, using the iconic Spectrum as its case study.

The book also acts as a vital reference for the booming "retro-computing" community. Enthusiasts looking to build their own replica ZX Spectrums (such as the Harlequin project) or create entirely new 8-bit computers rely on the comprehensive logic descriptions found in the book to write VHDL or Verilog code that accurately mimics the original Ferranti ULA behavior.

Today, the knowledge provided in The ZX Spectrum ULA: How to Design a Microcomputer is used to create: Enthusiasts looking to build their own replica ZX

This book is often cited as the definitive resource for developers creating hardware clones (like the Harlequin) or FPGA-based replicas of the ZX Spectrum. It provides the necessary logic gate-level information to recreate the ULA’s functionality in modern CPLD or FPGA devices. Amazon.com.be The ZX Spectrum Ula: How to Design a Microcomputer
