Probably The Cheapest Mac Emulation Hardware

There are many ways to build your own Macintosh clone, and while the very latest models remain a little inaccessible, there are plenty of Intel-based so-called “Hackintoshes” which deliver an almost up-to-date experience. But the Mac has been around for a very long time now, and its earliest incarnation only has 128k of RAM and a 68000 processor. What can emulate one of those? Along comes [Matt Evans], with a working Mac 128k emulated on a Raspberry Pi Pico. Such is the power of a modern microcontroller that an RP2040 can now be a Mac!

The granddaddy of all Macs might have been a computer to lust after four decades ago, but the reality was that even at the time the demands of a GUI quickly made it under-powered. The RP2040 has plenty of processing power compared to the 68000 and over twice the Mac’s memory, so it seemed as though emulating the one with the other might be possible. This proved to be the case, using the Musashi 68000 interpreter and a self-built emulator which has been spun into a project of its own called umac. With monochrome VGA and USB for keyboard and mouse, there’s MacPaint on a small LCD screen looking a lot like the real thing.

If you want a 1980s Mac for anything without the joy of reviving original hardware, this represents an extremely cheap way to achieve it. If it can be compiled for microcontrollers with more available memory we could see it would even make for a more useful Mac, though your Mac mileage may vary.

Of course, this isn’t the only take on an early Mac we’ve brought you.

There are dozens of different 3D printable cases out there for the Raspberry Pi, but the BeagleBone Black, as useful as it is, doesn’t have as many options. The folks at 3D hubs thought they could solve this with a portable electronics lab for the BBB. It opens like a book, fits a half-size breadboard inside, and looks very cool.

The guy who 3D printed his lawnmower has a very, very large 3D printer. He now added a hammock to it, just so he could hang out during the very long prints.

There’s a box somewhere in your attic, basement, or garage filled with IDE cables. Wouldn’t they be useful for projects? Yep, only not all the wires work; some are grounds tied together, some are not wired straight through, and some are missing. [esot.eric] has the definitive guide for 80-wire IDE cables.

Like case mods? Here’s a golden apple, made out of walnut. Yes, there are better woods he could have used. It’s a wooden replica of a Mac 128 with a Mac Mini and LCD stuffed inside. Want a video? Here you go.

If you have a 3D printer, you’re probably familiar with PEEK. It’s the plastic used as a thermal break in non-all-metal hotends. Now it’s a filament. An extraordinarily expensive filament at €900 per kilogram. Printing temperature is 370°C, so you’ll need an all-metal hotend.

It’s the Kickstarter that just keeps going and going and going. That’s not a bad thing, though: there really isn’t much of a market for new Amiga 1200 cases. We’ve featured this project before, but the last time was unsuccessful. Now, with seven days left and just over $14k to go, it might make it this time.
