Summary
A maker built a miniature Macintosh computer using a Raspberry Pi Pico running Matt Evans' Pico Micro Mac firmware. The project outputs to a 640x480 VGA display at 60Hz and supports USB keyboard and mouse input. Despite the Pico's memory constraints, the setup provides 208KB of RAM, which is 63% more than the original 128K Macintosh. The article documents the hardware assembly and technical specifications of this retro computing project.
