What is it?

A plug-and-play, hand-soldered single-board computer that crams a complete 1984 Macintosh 128K environment into a matchbox-size PCB built around the Raspberry Pi RP2040. A 16 MB NOR flash holds the system ROM and a bootable disk image, while a micro-SD slot lets you swap additional classic Mac images at will. The on-chip dual-core Cortex-M0+ emulates the 68k CPU, 208 KB of SRAM is reserved for Mac memory, and a tiny VGA DAC pumps out an authentic 640×480 black-and-white picture. Two full-size USB-A ports accept standard keyboards and mice; simply plug in, power over USB-C, and watch the smiling Mac greet you in under two seconds.

Why did you make it?

Like many hobbyists I was blown away by Matt Evans’ open-source “pico-mac” emulator but didn’t want a tangle of jumper wires on my desk. I designed a single, manufacturable PCB that keeps every part firmly in place, adds reliable flash storage, brings out convenient USB host ports, and fits in a cute 3-D-printed 62 mm “Classic Mac” shell . The goal was to give retro-computing fans, students, and collectors a tiny, worry-free turnkey machine that can be carried in a pocket yet still runs System 1.1, MacPaint and even early HyperCard stacks.

What makes it special?

Zero-compromise emulation: cycle-accurate 68k core, original 128K ROM, 400 KB floppy images, and the legendary 1-bit “beep” recreated with a 600 Hz square-wave chirp on boot .
Ready to use: every SMD part professionally soldered, RP2040 pre-flashed, USB-C cable included—no toolchain or firmware tinkering required.
Flexible storage: 16 MB on-board NOR flash holds a default boot disk; TF-card slot accepts additional *.dsk files for drag-and-drop software swapping.
Big-system feel: native 640×480 VGA output drives any monitor or projector; full-speed USB HID support means modern keyboards, mice and even some wireless combos work out of the box. Open heritage: board files, Gerbers and BOM are released under the same MIT license as the upstream pico-mac project, so you can hack, extend or remix to your heart’s content .
