: Explains how the ULA handles timing and output for 1980s television sets. Memory Contention
For decades, aspiring hardware developers have asked the same question: How did they design a complete microcomputer using only one custom chip? The answer, partially, lies in obscure technical documents. One such reference that has surfaced in deep archive searches is the filename . This article will dissect what that document likely contains, how the ULA works, and how you can use such schematics to design your own retro-inspired microcomputer.

The ULA was a "blank" chip from Ferranti, a grid of generic transistors waiting for a purpose. Altwasser had to weave these into a master conductor that would synchronize the Z80 processor, manage memory, and paint 256x192 pixels on a screen. : Explains how the ULA handles timing and
