Zilog Z80 Microprocessor Introduction

A middle-aged man with a wiry build, short brown hair slightly graying at the temples, and rectangular wire-frame glasses that reflect the glow of the oscilloscope. His face shows faint lines of concentration and long hours spent squinting at schematics. His hands are steady but bear small nicks and burns from years of working with electronics.

A young man in his early 20s with a wiry build, short brown hair slightly tousled from working long hours, and bright, eager eyes behind round wire-frame glasses. His face bears traces of youthful enthusiasm mixed with the fatigue of late-night debugging sessions.

A woman in her late 20s with a lean build, shoulder-length brown hair tied back in a practical ponytail, and sharp hazel eyes that scan equipment with precision. Her hands move with practiced efficiency, fingers slightly calloused from frequent handling of delicate components.

A middle-aged man in his late 40s, with a lean build and sharp features. His hair is neatly combed, showing traces of gray at the temples, and his clean-shaven face exudes an air of authority. His piercing eyes scan the room with calculated interest.
