I will presume that you know of the more recent tome on the ULA? "The ZX Spectrum Ula: How to Design a Microcomputer" by Chris Smith

  Know of but don’t (yet) own. Strong recommendation?

    I like it. It’s bottom-up, and I’d go as far as saying it’s the definitive book on the Speccy ULA. http://www.zxdesign.info/book/ http://www.zxdesign.info/book/
