From the project

KiCad projects (schematics and boards) for a full-diy ZX Spectrum replica

All boards that I designed, etched and soldered to create a full-diy replica of ZX Spectrum. Kicad4 (just a keyboard) and Kicad5

This is NOT a cycle-perfect replica so do not expect to launch fancy demos on it. The project started as a breadboard simplest possible computer using Z80. Quite quickly I started thinking of making a replica of ZX Spectrum - the first computer I ever used as a kid. All I wanted was to:
