A Uncommitted Logic Array (ULA) is a type of integrated circuit that consists of a matrix of programmable logic blocks. These blocks can be interconnected to create a wide range of digital logic functions, making ULAs highly versatile and ideal for complex digital system design. In the case of the ZX Spectrum, the ULA was designed to integrate many of the computer's core functions, including memory management, I/O control, and graphics processing.

The book uncovers hidden features and explains infamous issues like the "Snow Effect".
