Retro Hackintosh Made From Retro Parts

Apple as a company, has staked most of its future around being a “walled garden” where it controls everything from the hardware up through the user experience. In some ways this is good for users; the hardware is generally high quality and vetted by the company creating the software, making for a very uniform experience. This won’t stop some people from trying to get Apple’s operating systems and other software running on unapproved hardware though. These “Hackintosh” computers were much more common in the Intel era but this replica goes even further back to the Macintosh era.

Originally [Kevin] had ordered an authentic Macintosh with the intent of getting it working again, but a broken floppy disk drive and lack of replacement parts turned this project into a different beast. He used the Mac instead as a model for a new 3D-printed case, spending a ton of time sanding, filling, and finishing it to get it to look nearly indistinguishable from the original. The hardware going in this replica is an old Linux-based thin client machine running the Mini vMac operating system, with a modified floppy drive the computer uses to boot. A hidden SD card slot helps interface with modern computers. The display is a modern LCD, though a sheet of acrylic glued to the front panel replicates a bit of the CRT curve.

Macintosh Classic II With E-Ink Display

As various antique computers age, it becomes increasingly hard to operate them as hardware begins to physically fail. Keeping these systems up and running often requires scavenging parts from other machines which are only becoming harder to find as time goes on. But if you throw out the requirement of using only era-appropriate components, there are some interesting ways to revive older devices with a few touches of modern tech, like this Mac Classic with a unique display.

The Macintosh Classic II was the successor to the first Macintosh computer Apple sold that had a price tag under $1000. As such, there were some lower specs for this machine such as the monochrome 512×342 display. This one has been retrofitted with an e-ink display which actually gives it some of the same grayscale aesthetic as the original. The e-ink display is driven by a Raspberry Pi which displays a replica System 7 environment and a set of photos.

While the only part of the computer that’s original is the shell at this point, the project’s creator [Dave] also built in support for the Apple Desktop Bus through an Arduino so the original Apple mouse and keyboard can be used. While it’s largely an illusion of a working Mac Classic, we still appreciate the aesthetic.

If you’re more of a classic Apple purist, though, take a look at this SE/30 which uses almost entirely original parts with the exception of a Raspberry Pi to allow it to communicate with the modern Internet.

Bringing IMessage To The Mac

If you’ve invested in the Apple ecosystem, the joys of iMessage likely illuminate your life. Your phone and desktop and laptop all sync your messages. But what if your desktop is running Mac OS 9 or System 2? This is where [CamHenlin’s] MessagesForMacintosh comes in.

Unfortunately, it does require a more modern Mac to act as an access point into the wider iMessage network. The modern Mac sets up a GraphQL database that can be accessed. Then a serial cable connects your “retro daily driver” to a translation layer that converts the serial commands into GraphQL commands. This could be something simple and network-connected like an ESP32 or a program running on your iMessage Mac. [CamHenlin] has a second Mac mini in his demo, seen above.

[CamHenlin] leverages his library known as CoprocessorJS. It allows older machines to hand off complex workloads to more modern machines, allowing modern machines to act as a coprocessor. Getting a single binary to run across many different versions of Mac OS and System is tricky and there were a few tricks involved. Retro68 is a C++17 compiler that targets PowerPC and 68k architectures. Additionally, Nuklear Quickdraw is used to provide a GUI in a performant manner.

It is always a joy to see older hardware do new tricks, often with the help of a bit of modern hardware. Connecting your Mac to the internet can be as easy as Pi.

Classic Macintosh Gets An IPad Infusion

We know the classic Mac fans in the audience won’t be happy about this one, but the final results are simply too clean to ignore. With a laser-cut adapter and a little custom wiring, [Travis DeRose] has come up with a repeatable way to modernize a Compact Macintosh (Plus, SE, etc) by swapping out all of its internals for an iPad mini.

He goes over the whole process in the video after the break, while being kind enough to spare our sensitive eyes from having to see the Mac’s enclosure stripped of its original electronics. We’ll just pretend hope that the computer was so damaged that repair simply wasn’t an option.

Anyway, with a hollow Mac in your possession, you can install the adapter that allows the iPad to get bolted in place of the original CRT monitor. You won’t be able to hit the Home button anymore, but otherwise it’s a very nice fit.

Those with some first hand iPad experience might be wondering how you wake the tablet up once the Mac is all buttoned back up. That’s an excellent question, and one that [Travis] wrestled with for awhile. In the end he came up with a very clever solution: he cuts into a charging cable and splices in a normally-closed momentary push button. Pushing the button essentially “unplugs” the iPad for a second, which just so happens to wake it up. It’s an elegant solution that keeps you from having to make any modifications to that expensive piece of Apple hardware.

If there’s one thing we’re not thrilled with, it’s the empty holes left behind where the ports, switches, and floppy drive were removed. As we’ve seen in the past, you can simply cut the ports off of a motherboard and glue them in place to make one of these conversions look a little more convincing. If you’re going to do it, might as well go all the way.

The Other Way To Brick A Mac Classic

Why would you build a mini Mac Classic using LEGO and a Raspberry Pi? Well, why wouldn’t you?

[Jannis Hermanns] couldn’t find a reason to control this outburst of nostalgia for the good old days of small, expensive computers and long hours spent clawing through the LEGO bin to find The Perfect Piece to finish a build. It turns out that the computer part of this replica was the easy part — it’s just an e-paper display driven by a Raspberry Pi Zero. Building the case was another matter, though.

After a parti-colored prototype with whatever bricks he had on hand, a session of LEGO Digital Designer led him to just the right combination of bricks to build an accurate case, almost. It turns out that the stock selection of bricks in LDD won’t allow for the proper proportions for the case, so he ordered the all-white bricks and busted out the Dremel. LEGO purists may want to avert their eyes from the ABS gore within, but in the end the case worked out and the whole build looks great.

Fancy a full-size Mac Classic reboot? How about this iPad docking station? Or if tiny and nostalgic is really your thing, this retro-future terminal build is pretty keen too.

Hackaday Links: January 22, 2017

What is a 1971 Ford Torino worth? It depends, but even a 2-door in terrible condition should fetch about $7 or $8k. What is a 1971 Ford Torino covered in 3D printed crap worth? $5500. This is the first ‘3D printed car’ on an auction block. It looks terrible and saying ‘Klaatu Varada Nikto’ unlocks the doors.

Old Apple IIs had a DB19 connector for external floppy drives. Some old macs, pre-PowerPC at least, also had a DB19 connector for external floppy drives. These drives are incompatible with each other for reasons. [Dandu] has a few old macs and one old Apple II 3.5″ external floppy drive. This drive can be hacked so it works with a Mac Classic. The hack is simply disconnecting one of the boards in the drive, and it only reads 400 and 800kB disks, but it does work.

The US Army is working on a hoverbike. Actually, it’s not a hoverbike, because it doesn’t have a saddle or a seat, but it could carry 300 pounds at 60 mph. That’s 136,000 grams at 135 meters per second for the rest of the world out there. This ‘hoverbike’ will be used for very quick resupply, and hopefully a futuristic form of jousting.

Over the past few months, we’ve seen a few new microcontrollers built around the RISC-V core. The first is the HiFive1, a RISC-V on an Arduino-shaped board. The Open-V is another RISC-V based microcontroller, and now it too supports the Arduino IDE. That may not seem like much, but trust me: setting up the HiFive1 toolchain takes at least half an hour.

The NAMM show has been going on for the last few days, which means new electronic musical gear, effects pedals, and drum machines. This is cool, but somewhat outside our editorial prerogative. This isn’t. It’s a recording studio using a Rasberry Pi. Tracktion is working on a high-quality digital audio input and output add-on for the Pi 3. This is really cool, and you only need to look back at MPCs and gigantic Akai samplers from 15 years ago to see why.

Hey LA peeps. Sparklecon is next weekend. What’s Sparklecon? The 23B hackerspace pulls out the grill, someone brings a gigantic Tesla coil, we play hammer Jenga, and a bunch of dorks dork around. Go to Sparklecon! Superliminal advertising! Anyone up for a trip to the Northrop ham meetup next Saturday?

Art For Planespotters

We don’t know art, but we know what we like. And this gizmo by [Johan Kanflo] is right up our alley.

First, [Johan] gutted an old Macintosh Classic computer and stuffed a Raspberry Pi inside. Now this is not really a new idea, but [Johan] did a very nice job with the monitor and his attention to detail shows in the rebuilt floppy-drive eject mechanism. He gives it back that characteristic “schlurp” noise.

Then he outfitted the Raspberry Pi with an RTL dongle running dump1090 software to listen to the ADS-B radio signals. The data extracted from the SDR is piped off to an MQTT server with all sorts of data about the airplanes overhead. Another script subscribes to the MQTT topic and figures out which is the closest and runs an image search for the plane type in question, publishing the results back to another MQTT topic. One final script subscribes to this last topic and displays the relevant images on the screen. Pshwew!

The end result is a Macintosh Classic that’s continually updated with whatever planes are closest to being overhead. We’re not at all sure if this is fine art, or part of the useful arts, or maybe even none of the above. But we really like the nice case job and think that using MQTT as a back-end for coordinating multiple concurrent Python scripts (on the same computer) is pretty cool.
