: This custom chip handled video display generation, keyboard input, tape input/output, and speaker audio.

This document (referenced as ZX_Spectrum_ULA_How_to_Design_a_Microcomputer_v57l.pdf ) is a technical deep dive into the heart of the Sinclair ZX Spectrum – the Ferranti ULA (Uncommitted Logic Array). Targeted at hardware hackers, retrocomputing enthusiasts, and digital designers, the guide explains not only how the ULA works but also how its architecture influenced the design of a complete, low-cost 8-bit microcomputer.

: In-depth analysis of timing and conflicts between the CPU and ULA. Bugs & Features

: Insights into timing issues and how the ULA manages RAM access with the Z80 CPU. : This custom chip handled video display generation,

I can help you explore how to simulate ZX Spectrum ULA logic using modern FPGAs .

On paper (or via a CAD system like Daisy or Applicon), engineers drew gates. For example, the video shift register was built inside the ULA using 8 flip-flops. The address multiplexer for the DRAM was a set of tri-state buffers. The PDF is not officially free, but you
