[Andrew] was left wanting by the slow hard drive in his 2011 Mac Mini. He set out to add a 10,000 RPM drive and we think he did a great job of pulling it off. Luckily he also took the time to document the process so you can try it yourself.

As with a lot of Apple products, a big part of this hack is just getting the darn thing apart without breaking something. Once that’s done, you’re got to do a little bit of interface hacking. To save space Apple uses a non-standard SATA breakout cable so [Andrew] starts by ordering a second hard drive cable from the company. He then soldered a thin wire connecting 12V from the motherboard to the 12V pin on a SATA connector. From there it’s just a matter of altering the original hard drive sled to make room for the 500 GB WD Velociraptor drive. It fits below the original and serves as additional space instead of as a replacement.

Around this time last year, [Sprite_TM] took a 1980′s-era Macintosh SE and rebuilt it as a home file server. He used a Seagate Dockstar as the new motherboard, but over the past year he’s been annoyed with the fact that the Dockstar doesn’t have real SATA ports. Using USB to SATA converters on a server is a slow way of doing things, so [Sprite_TM] rebuilt his SE using an HP thin client. To do this, he had to break out the onboard SATA and PCIE; not an easy task, but that’s why [Sprite_TM] is around.

The first order of business was installing a pair of SATA ports. The stock thin client had two NAND-flash chips serving as the drive, both connected to a SATA controller. All [Sprite_tm] had to do was desolder the flash chips and wire up the new SATA connections. Easy enough.

Because the HP thin client only had 100Mbps Ethernet, [Sprite_tm] wasn’t looking forward to the order of magnitude difference between his expected rsync speeds and what he would get with a 1Gbps connection. The only problem is the thin client didn’t have a spare PCIE connection for an Ethernet card. That’s really no problem for [Sprite_tm], though: just desolder the GPU and run a few wires.

Just like last year’s work on his SE, [Sprite_tm] ended up with a functional and very cool home server. The old-school System 7 is still there, and of course he can still play Beyond Dark Castle. Awesome work, in our humble opinion.

As a new recruit to the 68k Macintosh Liberation Army, [dougg3] is really showing off his hardware hacking ability. He came up with a replacement ROM SIMM for his Mac IIci and made it play the Mario theme on boot instead of the normal chimes.

Swapping out the ROM in these old macs isn’t an uncommon procedure. On some 68k machines, there’s a SIMM slot to either replace or expand the soldered ROM. In fact, it’s fairly common to take the ROM SIMM out of a IIsi and put it in the king of kings computer to make an SE/30 32-bit clean. We’ve never seen a re-writable ROM SIMM for these old macs, so we’re pretty sure [dougg3] just spared a Mac IIsi from the dumpster.

Now that the entire 68k Liberation Army is clamoring for one of [dougg3]‘s re-writable ROMs (we’ve got cash), the question of what to do with it comes up. Of course, SE/30s can now be 32-bit clean without installing MODE32 and new startup chimes can be added. We’d really like to see some hard-core ROM hacking going on, like installing a 68060 in a Quadra 950.

[Steve] over at Big Mess O’ Wires has never been so happy to see the “Sad Mac” icon.

A little over a month ago, he decided to take on the task of building his own Mac clone using modern technology. Not to be confused with Mac emulation on modern hardware, he is attempting to build a true Mac clone using an FPGA that is functionally identical to the original.

He is calling his creation the “PlusToo”, with the goal of producing a modern version of the Macintosh Plus. The Plus shares a good amount of hardware with its other original Mac brethren, allowing him to replicate any of the other machines such as the Mac 128K, with a few simple configuration changes.

Building this clone is an incredible undertaking, and it’s a lot of fun to watch the construction progress bit by bit. [Steve] has been diligently working for a little over a month now, recently getting the clone to run 68000 code from the Mac ROM, resulting in the Sad Mac image you see above. While the logo has been dreaded among Mac users for years, it signals to [Steve] that things are coming along nicely.

If you find a crusty old IT guy and give him half a chance, he’ll probably regale you with stories of how things were done “in the old days” where no one had their own computer and everyone worked on mainframe-connected dumb terminals. [JSTN] yearned for a true to life terminal display that he could attach to his 2010 Mac Pro, and since there’s no chance anybody is bringing one to market any time soon, he pieced one together on his own.

He dug up a digital VT220 terminal, and got to work trying to interface this office relic with his shiny new Mac. He found a few helpful tips from someone who did the same thing with an Apple ][c, though that solution relied on emulating a terminal - something he did not want to do.

He connected the VT220 to his computer using an off the shelf USB to serial adapter, but the software side of things still needed attention. A quick gettytab tweak later, he had his hardware terminal up and running without much trouble.

He says that he is more than happy to help anyone do the same, so let the mad eBay scramble for old terminals begin!

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.

So the machine I bought for the price of removing its zip drive is a 1997 powermac 9600 with a 300Mhz 604e motoroloa power pc cpu, stock 64 megs and a 8 meg non accelerated video card. These sold for 4,200 bucks new.

This one however was part of an AVID system and came to me loaded with every PCI slot filled with video gear, SCSI2, and 256 megs of ram in 8 out of 12 slots (32 meg sticks). It still had its *bitchy Rocket128 8 meg video card, and luckily a Targa2000 card with VGA output.

The cards, while impressive, are practically useless. Even if I had the dongles required to run avid stuff its mid 90′s technology that eats great amounts of power. All of these double board full length heaters were removed except for the Targa2000 card because of its VGA output. I don’t have a Macintosh monitor or adapter. Regarding the Targa2000 video card, its a fine card for the era, but a card made in this century would be awesome. With this video, mac os works, 8.x is snappy but a little limited. 9 is a dog 9.2 is better but its nothing impressive, any generic pci svga card could do the same, and so video became issue #1.

Video is kind of tricky for mac, it has to have its own rom, and its 2x as large as a standard pc rom (512Kbit vs 1024Kbit), So the first thing to do is find out what cards were available as “mac editions”.

Looking at The Mac Elite Software Downloads will give you an idea of what you can use. I have a power pc machine and would like to use an original rom, so that reduces my list down to the first table. The other tables include some roms for intel based machines, reduced (in attempt to fit the large mac rom on a smaller pc rom chip) and modified which are not really supported cards, so good luck.

To install these roms you pretty much need an x86 IBM compatible machine to use the rom flash software, and your card is going to need to have that 1mbit rom. This posed a problem cause at this moment all my pc’s with pci slots are toast, and the one card I have that might work is a 9250 with a pc rom, and the only mac side updater I could find still available for download was for OSX and this mac by nature will not go past 9.04.

Moving on I started reading about the radeon 7000. It is a pretty darn fast card for this machine, I could find mac os9 rom updates and drivers for it, and you can get the PC versions all day for cheap! Traditionally people would go on a hunt for a couple brands of cards that offered both PC and Mac versions and just never changed to the smaller rom for PC use. Those cards dried up pretty quick and if you see one now its going to cost an arm and leg (a 10 year old mac edition card used is like 40 bucks new around 100!).

During my search for software (ATI mac drivers went bye bye when AMD came in) I ran across an old site where dude grabbed any old pc 7000 and cut off the rom with a pocket knife and soldered a larger one in its place using a stove and a flathead screwdriver. He then proceeded to put it in his pc for the old 2 flash process but wondered if that was even needed. In fact no it isn’t! You can put a radeon7000 with a correct size blank rom in a mac and it will update it just fine.

I got online and instantly found a pc-pci version 7000 with 64 megs of ram brand new for 14.99 with free shipping. Once the card arrived I checked its rom and found it to be a nothing special 512Kbit 25×512 SPI eeprom that everyone has made at one point or another. I then dashed off to digikey and found a 25LC1024 made by microchip that would fit on the pads. Once that arrived I tried my best to do a professional job removing the chip, and yep a guy with a stove and a flathead had no problem, but I hosed the ground pad (doh!) … its nothing a little bit of 30 guage cant fix.

At this time I have a 15$ card with a 6$ (including mail) chip sitting on it and no bios. We need to correct that. First and foremost you need at least system 9.While I was waiting for all that shipping to happen I started upgrading my OS. The machine came with OS8.1? and I had a OS9.04 on a CD, which is the max this machine will take without some fiddling. MacOS9.04 is dreadfully slow and every other mac application you try complains about wanting 9.1 or 9.2(the last version of classic OS). Thankfully some people have sat down and cracked this problem in a program called OS9 helper. Using this program and the update disk images (US English available from apple, but I found a set for the international crowd too) you’re just a hop skip and jump away from 9.22 and the latest ATI drivers for a 7000 and much more!

Now we are ready to finish up that ATI card, insert the card into a unused slot, I wont remove the working video card yet. Then I fired up the mac and downloaded R7000-ROM-208.hqx and ati-retail-9-2-2-jan2005.hqx. Decoded and extracted both, ran the rom updater first. This will bring up a little ui asking if you want to update. It should only take a few moments to flash the blank rom and when it says that it is good. I am now ready to remove the old Targa2000 card and install the drivers.

This R7000 makes a HUGE difference in classic mac OS, where as before you could almost watch the Targa card draw windows, and Classilla (a mozilla browser for mac os9) was scrolling web pages about as my 386 would, I am now in a land of accelerated 2D and 3D graphics, Classilla is pretty useable and the computer plays a pretty mean game of Quake3 Arena @1024×768 all options cranked, but the issue is OS9.22 is very old in computer terms, software support is long gone and its still pretty slow just from its age. Besides what if I want to program my avr’s? Or get to a datasheet that is buried behind some java script? Really for this thing to be useable it needs a modern OS, something light but easy and can run on a Power PC cpu, with a ton of tools and programs, something Like Debian PPC…

I downloaded the newest version of Debian PPC as a 200 meg small CD. There are full cd’s and DVD’s but this one gets what you want off the net so its more practical for me. In order to boot linux on what is called a “Old world Mac” you need a bootloader and a place to install your distro. The main bootloader that works on these old machines is called bootX (linux). It is old and unsupported but works like a charm. The down side to it is you need to at least partially boot into OS9 first, so yeah, you have to keep OS9 around, even if its a tiny install.

As far as a place to install my copy of linux, I have a 9.2 gig SCSI (all the drives are SCSI in this old of a mac) that came out of a PC. Unfortunately, yes macs are a pain in the butt about hard drive’s too, and require that they also have a apple driver loaded onto them before the machine can use it. In the past you needed to use tools like “Hard Disk Toolkit”, which were commercial packages, that do just an OK job. Luckily people have patched apples own drive tools so you can initialize partition and format any drive. These tools do not like my install of OS9.22, so in order to use them, I had to use an OS8 boot disk.

I don’t need to partition and format the drive that linux is going on, but it does need its driver “updated” and initialized, which spatters data onto some special partitions so the computer knows what the heck you’re talking about later when you’re asking it to access the drive. In my situation the linux partitioner would not even see the drive until it been initialized.

I have a boot loader, and I have a decent enough disk to put linux on without killing my OS9 fun drive, so lets get this CD spinning! I extracted the bootX bootloader onto my desktop. Inside the folder is the application, a folder for linux kernels, and a system extension so when you’re done you can set it up where you dont have to go all the way to the OS9 desktop first before starting linux. I put the Debian CD into the drive and copied off the vmlinux and initrd from the install\powerpc folder to the bootX linux kernels folder. Start up bootX and point the kernel selection to the vmlinux off of the Debian PPC linux disk, and then point it to use the initrd ram disk also from the CD and click linux.

Sometimes if the CD was not in the machine at boot it will try and lock up. Just reboot and try again. Otherwise you should be greeted by the usual linux text chatter, then eventually launched into a basic text based installer. Simply follow the menus for the most part. When you arrive at the partitioning section it does not really matter how you partition the disk, just keep in mind to not wipe your OS9 partition or any partitions from the Apple disk drivers. So any option except use entire disk is probably safe. Also at this time it is wise to write down where the different linux partitions are, I have a boot partition at /dev/sdb7 and a root partiton at /dev/sdb8, though really I should have just stuck it all in one partition as the boot partition does not really do anything.

This is the trickiest part of the install. Debian will try to install another bootloader. You might get lucky and it might work. I have tried on a half dozen machines over the years and I have not gotten it to work, and it did not work this time either. That is fine just ignore it. The trick is to get the now customized linux kernel and ramdisk from my boot partition to my mac OS partition. Most tutorials on installing Debian on a “old world” machine say “just mount it and copy”, some even suggest using a apple prodos partition but never mention how to mount it … This install of Debian had no clue what a HFS+ disk was and I tried a dozen different ways to get it mounted or copied over. In the end the final part I needed for my main desktop computer had made it in the mail so I just gave up, used a PC SCSI card and linux on my PC to copy the 2 files off of the drive and just emailed it to myself on the mac.

Now that I have the boot files for my machine I just point bootX to use those, tell it where my root drive is, and within a few moments I am sitting at a nice little login prompt. A few apt-get installs later I was starting to build up my software. I had chosen, in the installer, to just give me a basic command line machine, if I had chosen “gui desktop” then I would have been loaded down with GNOME and a bunch of stuff I did not want or need on this machine, so I choose to install it myself. I ended up with xorg as a display server and XFCE as a desktop manager. Overall its pretty darn snappy for a 14 year old computer if you let an application or webpage load before messing with it, and over the month or so I have been using it near daily I have been happy and impressed with its performance.

Here is a short video of it coming up from a cold boot, into OS9 then into bootX, then into console linux into XFCE, which loads up a gecko browser, pdf reader, task manager, IDE, terminal and file manager along with all the desktop stuff in a reasonable amount of time. Sure its not going to break any speed records, but if you had to be stranded with this computer you would live quite comfortably. As far as its retro appeal goes, this machine is able to boot as low as macOS7 so you can get a ton of retro ware running on it, and was one of the very last models that was able to read and write Apple’s funky 800k DD floppy disks which is invaluable for my mac SE. The fact that I was able to keep it around as a cool old mac to poke around with and make it something that can be productive in my electronics work with near daily use makes this machine worth the hassle and the zip drive.

When you think about hacking laptops, it’s highly unlikely that you would ever consider the battery as a viable attack vector. Security researcher [Charlie Miller] however, has been hard at work showing just how big a vulnerability they can be.

As we have been discussing recently, the care and feeding of many batteries, big and small, is handled by some sort of microcontroller. [Charlie] found that a 2009 update issued by Apple to fix some lingering MacBook power issues used one of two passwords to write data to the battery controllers. From what he has seen, it seems these same passwords have been used on all batteries manufactured since that time as well. Using this data, he was subsequently able to gain access to the chips, allowing him to remotely brick the batteries, falsify data sent to the OS, and completely replace the stock firmware with that of his own.

He says that it would be possible for an attacker to inject malware into the battery itself, which would covertly re-infect the machine, despite all traditional removal attempts. Of course, replacing the battery would rectify the issue in these situations, but he says that it would likely be the last thing anyone would suspect as the source of infection. While using the battery to proliferate malware or cause irreversible damage to the computer would take quite a bit of work, [Charlie] claims that either scenario is completely plausible.

He plans on presenting his research at this year’s Black Hat security conference in August, but in the meantime he has created a utility that generates a completely random password for your Mac’s battery. He says that he has already contacted Apple to in order to help them construct a permanent fix for the issue, so an official patch may be available in the near future.

[Thanks, Sergio]

[Josh Wright] wrote in with a handy little hack just in time for today’s release of Mac OSX Lion. If you’re not familiar with the new version of the OS, Apple has decided to change things up this time around, completely eliminating physical distribution media.

In the event that you need to run a factory restore, this becomes an issue for some users. Computers with DVD drives can run a burned copy of the previously downloaded Lion installer, but MacBook Air owners are left hanging. Their restoration process is more time consuming, requiring a system restore and the download of OSX Lion, followed by the subsequent upgrade process. [Josh] thought it would be great if you skip the initial restore step and jump straight to installing Lion, so he hacked his USB restore media to do just that.

While copying the OS to a USB drive might sound trivial, the process is not as straightforward as it sounds – not surprisingly, Apple has put measures in place to prevent mere mortals from altering the contents of the drive. [Josh] put together an easy to follow tutorial that walks you through removing the drive’s protection and copying your brand new OSX Lion restore image to it.

While you might be asking, “Why jump through all these hoops when a normal flash drive would suffice?”, we think that his writeup is quite helpful. We see no reason to tie up a usable flash drive to store your restoration disc when you already have a perfectly good (albeit locked) drive at your disposal.

♦The only caveat to the process is that you need a Windows machine, virtual or otherwise, to complete the first step – a requirement that elicited a hearty chuckle from us.

Back in 2004, Apple hobbyist/guru [Michael Mahon] built a cluster of Apple IIe main boards dubbed the “AppleCrate” as an experiment in parallel computing. Now that a few years have passed, he is back with a new iteration of the device, aptly named AppleCrate II.

AppleCrate II was built to address some of the design limits of his first cluster project as well as to expand his parallel computing capabilities. His gripes with the first model were primarily structural in nature. The new system is organized in horizontal layers, using metal standoffs between each main board, rather than relying on a shaky wooden superstructure to keep things together. He also found his previous 8-processor configuration a bit limiting, so the AppleCrate II has 17 nodes – 16 slaves and one main board dedicated to running the operation. The cluster even uses his own homebrew networking stack known as NadaNet to enable communications between the boards.

The project is pretty impressive, so be sure to swing by his site if you want to learn more.  He has a ton of technical details there, as well as copies of all of the software he used to get the cluster up and running.

[Warrior_Rocker] pulled off his own Apple Studio Display hack by removing the cable and adding ports. As we saw in Wednesday’s post, these displays use a cable with a proprietary connector that combines DVI, USB and Power. Instead of altering the cable, [Warrior_Rocker] removed it completely. By wiring up a standard barrel jack for power, a USB type-B socket, and a DVI port, he can now use standard video, power, and USB cables to connect to the monitor.

This project was actually submitted to us on May 25th and we missed it. It’s sad that sometimes tips fall through the cracks, and we’re sorry that we missed this particularly well-executed hack. [Warrior_Rocker] wrote in asking why his project didn’t qualify after seeing the similar post on Wednesday. So please don’t take it personally if your project doesn’t get posted. If you think it fits right in here at Hackaday and haven’t heard anything after two weeks or so, consider sending to us again.

[Sprite_TM] cooked up an amazing hack by resurrecting a Mac SE using a Dockstar and ARM processor. The retro hardware had a bad mainboard thanks to the corrosive properties of a failed backup-battery. He had been wanting to do something with the Seagate Dockstar and decided it would find a nice home in the Mac. But what fun is a dead machine housing a headless server? To add to the fun he included an ARM processor running a Mac emulator, along with all the bits to make the screen, keyboard, and peripherals work. When the Mac is off the Dockstar still runs as a server.

But one of the best parts is the floppy drive. It still takes floppies, but there’s no magnetic media inside of them anymore. Instead, he’s added an SD card slot and some protoboard in the space for the read head. The drive itself has had the read head transplanted for some pogo pins (hey, we saw those earlier today). When you insert the floppy, the pogo-pins raise up and contact the protoboard, connecting the SD card to a Teensy microcontroller.

There’s so much going on with this project we just can’t cover it all here. Things like a chemical cleaning to return the original color of the classic case, and building a converter so that the peripherals are USB compatible are just some of the pleasures awaiting you in [Sprite_TM's] post. He’s also filmed a demo video that we’ve embedded after the break.

[Sherry Wu] sent in a link to her Apple Studio Display hack. She got her hands on the 17″ display which has a proprietary Apple Display Connector that rolls signals for DVI, USB, and 25V power into one plug. Convenient right? Not if you want to use it on a machine that has standard video connections. No problem, she got out her meter and figured out which wires belong to each signal. After some soldering she now has a DVI connector for the video, and a 24V bench supply is standing in for power until a dedicated unit arrives. No luck so far at getting the USB and hotplug detection to work but she plans to keep going until that’s accomplished.

Looks like you can pick these displays up refurbished for as low as $75. Might not be a bad addition to your home setup if you’re willing to do some soldering.

[John's] latest build strikes a chord of nostalgia by realizing the Banana Jr. 6000. The whimsical hardware is the product of the Bloom County comic strip. It first appeared in 1984, the same year as the Macintosh. [John] used a Mac Plus as the case but completely revamped the insides. An 8″ touchscreen takes the place of the original cathode ray tube. There’s also a Mac Mini and a couple of speakers salvaged from other Macs. To get things looking just right he altered the case’s logo, painted it yellow, and even altered the Leopard operating system. Now when you boot up you’ll see a Banana and not a partly consumed pomaceous fruit.

If you’ve been frustrated by the inability to skip past parts of DVDs on OSX the here is one solution. It’s a patch script that uses some binary hacking to remove the User Operation Prohibition locks from DVD playback software. Using UOP flags is a way to force users to watch trailers or warnings as part of the DVD experience. This script can patch Tiger, Leopard, and Snow Leopard systems. It also has the ability to generate diagnostic information for other installations that will lead to expanded support in the future.

[Enigma-penguin] built a tablet computer out of a Core2Duo Macbook circa 2007. The battery exploded, damaging the case and a few components inside. But there was hope for a new life as a tablet computer. He removed the screen and tested to make sure the computer would still function without it by using the video out port.

Putting the whole thing back together as a tablet proved to have some headaches. He worked through problems caused by the addition of a touchscreen between the LCD and the bezel and made the connections work with the screen flipped. The finished product looks so good because the bezel has not been turned around like on other tablet builds. Instead, a viewing window was cut in what would have been the case behind the screen.

There’s a little more to be done yet. The black USB cable seen above is the connector for the touchscreen which he plans to internalize. The magnetic sleep sensor has been relocated to the headphone jack. Inserting a plug (no cord necessary) puts it to sleep for transport. There’s also an on screen keyboard and the ability to change the screen orientation from landscape to portrait. After the break we’ve embedded one of [Enigma-penguin's] demonstrations.
