Apple PowerBook 2400c

This is the second installment of my "Adventures in old Tech" theme of posts. I hope you enjoy reading about one of my favorite laptops ever created.


Side Profile

The PowerBook 2400c has an interesting design history compared to other PowerBooks of the era. According to an article from MacWeek in 1999, the 2400c was co-designed by Apple and IBM Japan to fit this new "subnotebook" class of machines that Japanese consumers had started to gain an appeal for.

Top Profile

The 2400c was the smallest portable computer apple had made since the original PowerBook 100. It was so small in fact, that it only had room for an internal battery, it came with an external floppy disk drive (using a proprietary connector) and offered no external CD-ROM support other than the Mini-SCSI port.

PowerBook 2400c Keyboard

The keyboard and trackpad on this machine are pretty much garbage. The keyboard is almost too tiny to get anything done (remember the netbook craze of the mid-2000s?) ditto with the trackpad. Other than that, the design of this thing is quite nice. The translucent button to open the lid doubles as a green sleep LED indicator, and the generally curvy profile of the PowerBook is an interesting approach that we really wouldn't see again until the first wave of iBooks.

Technical Details

External Floppy Drive

My particular 2400c was originally a PowerBook 2400c/180, meaning it came with a 180MHz 603e PowerPC processor. I say originally, because I took advantage of upgrading this using VImage's PowerPC G3 upgrade kit. It included the processor and a driver that allows you to turn on and off the backside cache to save battery life. This brought my 2400c to 320MHz, which is more than a slight bump in performance.

Apple System Profiler

The other thing you'll notice about my 2400c is that it is running MacOS 8.6. The 2400c can support up to MacOS 9.1, which I have run on this machine, but I have found it to run with much better stability on 8.6 instead. 8.6 is a bit leaner and, quite honestly, in 2016 the differences in software and features between OS 8.6 and OS 9 are negligible at best.


From left to right, the ports on this machine are:

  • ADB
  • Power
  • Apple Serial
  • Floppy Connectory
  • VGA
  • Mini-SCSI
  • IrDA
  • 2 PCMCIA slots

An interesting note about the PCMCIA slots are that they can be compatible with the CardBus standard. The slots can technically fit CardBus cards, but by default the 2400c will simply reject them. By clipping and bypassing 2 resistors on the motherboard, you can activate using CardBus cards in the machine. I've tested this with a MacAlly USB card which provides 2 USB ports. I have used this to successfully transfer data back and forth on the machine using a flash drive.

One final hardware modification I performed was converting the loud and slow HDD for a quiet (and equally slow) compact flash card using a product such as this, it's actually quite easy to do. Once I put in the adapter and rebooted from the OS 8.6 CD, the installer saw the CF card as a regular HDD.


Mac OS 8.6 Boot Screen

Like I said above, the machine is running Mac OS 8.6. Most classic mac software that is compatible with OS 9 can run on 8.6. Here is a list of some of the applications I have installed on the machine:

iCab viewing the 2400c Profile on LowEndMac

Using the internet with this machine today is all but impossible. Almost any website that uses HTTPS fails to load in both iCab and Clasilla. Moreover in both browsers JavaScript needs to be disabled to prevent the system from having a meltdown.

One of the interesting things I was able to do is load a modern MP3 file onto the machine and play it back with iTunes. It worked quite well, actually and the little PowerBook even did a decent job rendering the visualizer, all things considered.

Another thing to note is the appearance of Mac OS 8.5. When Apple was moving from System 7 to Mac OS 8 (code named "Copland") they introduced a new appearence to the operating system that would stick until the death of OS 9, called Apple Platinum. There was always the tease for new themes and when OS 8.5 was being demoed there were three Apple-made themes that Steve Jobs did a demo on before its release. These themes never made it into the shipping version of OS 8.5, however. I was able to find a couple of these themes online, and my favorite of the bunch is called Drawing Board which can be seen in the picture below:

Old Tech Adventures: Part I

The year was 1991. Personal computing was just becoming popular and 5.25" floppy disks were all the rage. Enter the CD-ROM. There was so much more storage potential, the possibilities seemed endless. When Sony released one of their first CD-ROM drives, they packaged it with a compliation of 6 discs called the "Laser Library." I suppose if you're going to drop $1,200 on a new technology, you might as well get some stuff to play with.

One of these discs included the Microsoft's Bookshelf software. It was a DOS application that included a simple encyclopedia, a dictionary, thesaurus, quote-book, etc. I installed it on a FreeDOS virtual machine. First thing I did was try to define the word "internet." I guess it wasn't popular enough to have its own definition in 1991.

Stay tuned for more old technology posts as I dig through my library of treasures.

Aberlour A'Bunadh: A Review

Aberlour A'Bunadh

Aberlour A'Bunadh Batch No. 50. Highland Single Malt Scotch Whiskey, 59.6% ABV

  • Color: Deep wood, cherrywood-like, reddish hue to it
  • Nose: Lots of fruit, plum, peach and cherries, raisins, wood stain, port, sherry, honey, hot sticky jam (5/5)
  • Palate: Lots of sherry, also fruit, cherries, and alcohol, it's very strong Maple syrup, honey again, nutmeg, allspice (45/75)
  • Palate w/Water: Still a lot of sherry, but a lot of sweet notes come out, more maple syrup, rose hips, hibiscus, and the plum from the nose comes back (60/75)
  • Finish: Port wine, gingerbread, fresh-cut mahogany wood, pepper, cayenne, maybe sage? Some herbs. It stays with you a while, even between sips of water (9/10)
  • Mouthfeel: Thick, very thick. Leaves a strong coating around the palate (4/5)
  • Value: It's very good with a little water added to cut its strength down, so at least I get more mileage from it (4/5)

Total Score: 82/1000

I love sipping on this scotch in while cooking or as a start to my evening. It's strong and goes well with a splash of water or a single ice cube. I'm curious how other batches of A'Bunadh compare to batch 50.
