1-bit Rainbow has created the world's smallest working Mac called Pico-Mac-Nano, featuring a two-inch display and powered by a Pico Zero Raspberry Pi.
The tiny computer is a 3D printed replica of the classic Macintosh from the 1980s, runs the MicroMac 128K emulator, and is available for purchase fully assembled for just $59.
For those interested, 1-bit Rainbow also offers 3D printing files to create your own case and assemble it with a regular Pico Raspberry Pi at a lower cost.
There is a Collectors Edition available for $78 that comes packaged in a small-scale replica of Apple's original 'Picasso' Macintosh box.
