A large-scale analog computer inspired by ENIAC and other pre-transistor era machines. The model should feature a wall of interconnected vacuum tubes, rotary switches, patch cables, and blinking indicator lights. Include bulky metal cabinets, exposed wiring, and mechanical components like punched card readers and oscilloscopes. The design should reflect a 1940s–1950s industrial aesthetic with matte gray and beige tones, riveted panels, and vintage dials. Add subtle wear and tear for realism, such as faded labels and slight rusting on metal edges.
