Accurate simulation of a Z80 CPU and of a ZxSpectrum computer at the electronic level.

Based on the book "The ZX Spectrum Ula: How to Design a Microcomputer" : full reconstruction of the ZxSpectrum computer in software at the wire and clock signals level.

You can load all original ZxSpectrum games from tape captures and play.

The goal was to deeply understand the inner workings of a CPU and a rudimentary computer with all its peripherals at the electronic level, and to understand its operating system in assembly language.
