Walkmac revisited: The inside story of the 'first' portable Mac

A spring cleaning unearths a semi-rare Apple find, the Colby Walkmac, a "modded" portable Macintosh that predates Apple's Macintosh Portable.


Recently my brother-in-law, Ken Landau, was doing a major spring cleaning when he came across a bit of computing history in his basement: a Colby Walkmac, the first battery-operated Macintosh computer and first portable Mac with a LCD display.
I'd never heard of the Walkmac, which wasn't built by Apple but by electronics pioneer Chuck Colby, who founded Colby Systems in 1982. The Apple-sanctioned model you see here was "modded" around a stock Mac SE motherboard and hit the market in 1987, two years before Apple put out its Macintosh Portable in 1989 for $7,300. Subsequent Colby models were built around the SE-30 motherboard and had an integrated keyboard (that black mat in the picture above is a mouse pad).
Though certainly not nearly as rare as the Apple that just sold for $671,400, it's still somewhat rare.

How did my brother-in-law end up with one? Well, he worked at Apple from 1986-1992 (he started around the same time as Phil Schiller, Apple's senior vice president of worldwide marketing) and was investigating sales force automation options when Colby Systems sent him one.
According to Chuck Colby and DigiBarn computer museum in Northern California, "customers ranged from the Grateful Dead rock band to Peter Jennings of CBS News." Thousands of them were sold from 1987 to 1991, "and before Apple came out with their Portable, when anyone called Apple in search of a portable Mac, Apple gave them Colby's phone number."
Even after Apple released the Macintosh Portable, the Colby continued to sell because it had a faster processor (Motorola 68030) than Apple's portable (16MHz 68HC000).
However, after Sony threatened to sue over the name (too close to Walkman), Colby was forced to change it to Colby SE30, which wasn't quite as catchy.
That was then, this is now (click image to enlarge).

Here are this Walkmac's specs:
  • Model No.: CPD-1
  • Year Produced: 1987
  • Operating system: System 6.0.3
  • Processor: Motorola 68030 @ 16Mhz
  • Memory: 1MB
  • Weight: 13 pounds
  • Cost: Around $6,000 (or $11,935.96 today, based on inflation)
Landau, who today is the CEO of Mobileage, an iOS app developer (yes, that's the company'sGluey app on the iPhone and iPad), says the unit is missing a few parts, namely the plug-in hard drive and battery pack, but it does turn on. It's unclear how much it's worth, buteverymac.com has it fetching $25 to $50, though that is for a later model with an integrated keyboard (this is a very early unit).
According to Wikipedia, Chuck Colby is mentioned in Steve Wozniak's book iWoz as having introduced Wozniak to early satellite television. That was apparently "the impetus for Wozniak to leave Apple so he could design, then start a company to market the first programmable learning TV remote, the CL 9."
Apple's Macintosh Portable arrived in 1989 and cost $7,300.

What's Colby doing now? Well, last month he put his all-redwood house in the Palo Alto, Calif., hills up for sale for $4 million (Colby says it's the largest all-redwood house in the world). But there's a bit of twist if you want to buy it. According to the San Jose Mercury News'Silicon Beat blog, Colby's "offering it as a 'Life Estate' contract, which means the buyer will have to wait until Colby dies to move in."
Colby thinks he'll still be kicking for another 10 to 15 years but he expects the home will be worth substantially more by the time he dies. "It [Palo Alto hills real estate] has a really great return on your investment -- even better than gold, silver or Apple stock," he said.
No word on whether there are any takers.

Best tech gifts under $100 for Dad

Roku's speedy streamer is the best box yetThe good:The Roku 3's excellent new interface and faster processor makes it feel quicker and more responsive than any other streaming box. More than 750 channels are supported, including Netflix, Amazon Instant, HBO Go, Hulu Plus, Pandora, MLB.TV, Amazon Cloud Player, and Vudu. It also has cross-platform search that scours several major TV and movie services to find content. And Roku's nifty new remote has a built-in headphone jack that lets you listen without disturbing others. The bad:There's still no official YouTube channel. Some services have an outdated interface on Roku compared to other streamers. The Apple TV still works better within the Apple ecosystem. And the Roku 3 isn't a great option if you're mostly looking to stream your personal digital media collection. The bottom line:The Roku 3 is the best streaming-video box yet, with tons of content sources, lightning-fast performance, and an innovative remote wit…

'Star Trek II' producer talks Ceti Eel, J.J. Abrams, and more (Q&A)

Robert Sallin, producer of "Star Trek II: The Wrath of Khan," shares his experience working on the film, looks at the future of "Trek," and dishes on whether that was Ricardo Montalban's real chest.

The release of "Star Trek Into Darkness" has not only spurred interest in the "Trek" world in general, but especially in its film daddy, the original Khan-as-villain movie "Star Trek II: The Wrath of Khan." While the new film takes quite a few detours, it is full of homages to the earlier work. Let's look back to 1982. "Star Trek: The Motion Picture" had been released in 1979 and faced a poor critical reception. Paramount, the film's studio, was gun-shy after the movie nearly doubled its original budget, ending up with a $46 million price tag. Nonetheless, plans for a second movie plodded along. It's 30, 40 years later and we have new audiences. You can't keep dwelling on the old guys and the old things. It has…

Power-packed plasma shines brighter

The good:The Samsung PNF8500 series exhibits outstanding picture quality with a class-leading bright-room image, exceedingly deep black levels, very good shadow detail, highly accurate colors and superb off-angle and uniformity characteristics; mind-boggling feature list with touch-pad remote, IR blaster with cable box control, four pairs of 3D glasses, motion and voice command, and the industry's most capable Smart TV platform; unique styling with full-width ribbon stand and slim-bezel metallic finish. The bad:Extremely expensive; correct film cadence requires sacrificing some black level; remote lacks numerous direct commands; imperfect cable box control; consumes more power than LCD TVs. The bottom line:Samsung's best-performing TV ever, the PNF8500 series pushes the plasma picture quality envelope, especially in bright rooms.Amid the hubbub aboutPanasonic's financial troubleand questions about how it will affectthe future of plasma TV, it's easy to forget about Samsu…
