From the project

Mod del iMac G3 slot-loading (M5521) con Raspberry Pi 5: PCB maestra unificada, placas individuales (J20, J22, Down Converter), bezel interior y visores 3D. Todo en español.

Convierte un iMac G3 DV (slot loading) en un equipo moderno: una Raspberry Pi 5 dentro de la carcasa que usa el tubo CRT original como monitor VGA, con sus altavoces y su botón de encendido. Reversible: no hay que cortar nada del iMac.

Este repositorio reúne la documentación en español, las tres placas del proyecto original traducidas, un PCB master unificado que reemplaza el cableado entre ellas, y visores 3D (HTML autónomo y STL) para revisarlo todo sin instalar nada.
