For the first time, the inner working of the Sinclair ZX Spectrum's custom chip and heart of the computer, the Ferranti ULA, is exposed in minute detail.
Packed with over 140 illustrations and circuit diagrams, this book takes the reader through the cutting edge technology that was the Ferranti ULA and the design of the ZX Spectrum home computer, illustrating the principles and techniques involved in creating a cost effective computer that required nothing more than a television set and a cassette recorder.
The ZX Spectrum ULA is an essential read for the electronics hobbyist, student or electronic engineer wishing to design their own retro-style microcomputer or anyone with an interest in historical micro-electronic and digital design.
All topics are explained in simple yet precise terms, building on their careful introduction towards the full functionality presented by the Sinclair computer.
Some of the topics covered are:
The architecture of the standard microcomputer,
Ferranti and their ULA, manufacturing process and structure,
The functional layout of the ZX Spectrum ULA,
Video display generation,
Memory contention and timing,
ZX Spectrum design bugs such as "The Snow Effect",
ULA version differences.
Great book, fun read for those who remember those days or are in a mind to emulate it using FPGAs or similar!Published 6 months ago by Problemchild
Great book, written by someone that really knows about the Sinclair ZX Spectrum and the ULA.
Thanks a lot for this bible, I'm really glad that I managed to get one! :)
Well done to Chris Smith for his reverse engineering of the ZX Spectrum ULA. An essential read for anyone interested in the inner workings of retro hardware.Published 7 months ago by Tronix
