Uncovering easter eggs in old Mac ROMs

The picture you see above is taken from the ROM of a Macintosh SE made in the  late 1980s. This black and white image remained buried inside old Macs until [Adam] and [Trammell] at NYC Resistor reverse engineered these old Mac ROMs and found a few really cool Easter eggs.

[Adam] and [Trammell] have been dumping ROMs from old computers for a while now. Their modus operandi is finding old 27C-series EPROMs on old computers, prying the out of their comfortable home, slapping them in a breadboard, and wiring up an Arduino clone to dump the data to a computer.

Recently, the guys found an old Mac SE lying on the side of a road in Brooklyn and brought it over to NYC Resistor. They had known about images hidden in the SE ROM, but the guys wanted to know how and where these pictures were stored. After carefully inspecting the binary file generated from dumping the ROM, [Adam] was able to recover three images hidden in every Macintosh SE.

The folks at Apple – especially in the heady days of the Apple II and 68k Macs – hid quite a few Easter eggs in the ROMs of their computers. For instance, the Apple IIgs has audio data stored in the ROM, and the Macintosh Classic hid an entire operating system – System 6.0.3 – in the ROM of the machine.

Hacking 14 year old Power PC Mac back to life

For a while now I have been battling a dying 2.6Ghz dual core computer, but due to laziness and budget I just let it ride. At first it would occasionally crash in games, then it got to where it would crash during routine activities. After a year of this it would nail 105 degrees C in like 20 seconds and that is where the drama starts!

I threw my 2ghz “electronics” computer into my main machine’s case and used that for a few months. It’s motherboard had suffered from every electrolytic capacitor on it being puffy, but it has worked fine for nearly 5 years. I was surprised by the sound of what ended up being 2 caps blowing off of the geforce 7600 video card. In shock and excitement I removed the blown caps, slapped her back in and got another 4 months out of it before 2 more capacitors blew and took out a voltage regulator (and who knows what else with it).

Only armed with the craptop, I was stuck in a pickle! Then a co-worker came up to me and said “hey man you want this mac I only want its zip drive”. Well of course, going bonkers without my avrgcc, datasheets, and calculators, I took on the 14 year old Apple Power Macintosh 9600/300 as my bench machine, and I will now show you how I turned it from a novelty relic to a daily useful machine after the break.

VirtualBox beta runs Mac OS X

A new beta build of VirtualBox, Sun’s Oracle’s free x86 virtualization software, makes it possible to run Mac OS X as a guest operating system…no shenanigans or flaming hoops to jump through, just pop in the $30 retail Snow Leopard upgrade disc and go. This had previously only been possible with some awkward Hackintosh-style maneuvering, or using recent editions of commercial virtualization products.

Hacking the MagSafe

magsafe
This is a simple hack that could come in handy one day. [Mooner] wanted to use a Kensington universal power supply with his Macbook Pro, but found the adapters and peripherals involved “hideous”. His solution was to wire directly to the Kensington power supply. It’s pretty simple really, only a couple resistors are needed. It’s nice to have someone else do the research for you sometimes. While his final picture does look neat and tidy, we just don’t know how much of an improvement he’s made to the aesthetics. What do you think?

Mac mini in an old Apple II disk drive

Yo dawg, we heard you liked macs. [Charles] got sick of his Mac mini looking nice and pretty and decided to cram it into an old beige box. This old beige box just happened to be an old Apple II disk drive, so we guess that gives it some more street cred. The original disk drive sold in 1978 for $500. Man times have changed.

Apple forces Wired to take down netbook OSx86 video

bswind2

Wired Gadget Lab has taken down a video made by [Brian X. Chen] in which he gives a brief overview and demonstration of how to install OSX on an MSI Wind netbook. This apparently didn’t sit well with Apple, who contacted Wired and complained; Wired agreed and removed the video. Frankly, we’re disappointed with Wired’s response. While they were technically posting content which is questionable at best—in the video, Brian mentions that this is illegal and that it would be a good idea to have a retail copy of OSX on hand, but then goes on to point out that you can also download the hacked operating system off The Pirate Bay, Isohunt, etc—the video in and of itself wasn’t illegal, and thus Wired comes off as susceptible to what amounts to bullying by Apple. We’re all about creativity and innovation, and stifling that innovative spirit has never worked well in the long run.

Fortunately, if you’re feeling like you’ve missed out on the video, don’t despair: Gizmodo has posted the video on their website for you to view and enjoy.

Mac pro ultra mini

mac_pro_ultra_mini

[Matthew] sent in this slick project where he made a Mac pro Ultra Mini. He received a MacBook that had been killed by water. He took it apart, re-soldered some connections and was able to get enough of it working to be a decent multimedia machine for his tv. To make it look nicer, he found an external drive case that looks like a tiny Mac Pro. After a little bit of grinding, cutting, and zip tying he managed to get all the pieces inside the case.  We’re always happy to see hardware salvaged, and  to see it transformed to a fantastic looking useful machine is a bonus. Good job [Matthew].
