The ZX Spectrum ULA: How to Design a Microcomputer by Chris Smith is widely considered the definitive technical "forensic" guide to the heart of the Sinclair ZX Spectrum. It is highly regarded by electronics hobbyists and engineers for its detailed reverse-engineering of the Ferranti Uncommitted Logic Array (ULA).

This is precisely the logic you will find in the missing PDF. By copying this, you have designed a fundamental part of a video chip.

The ZX Spectrum ULA, also known as the Ferranti FPLA (Field-Programmable Logic Array), was designed by a team led by Chris Curry, a renowned engineer and designer. The ULA was fabricated using a 5μm CMOS process and contained approximately 22,000 transistors. This remarkable chip integrated many key functions, including:
