Inside the World\'s Greatest Keyboard - PC World

Today, PC World published the latest in my line of workbench tech autopsies. This time I dissected the venerable IBM Model M Keyboard, which some call the greatest keyboard of all time (obviously, I agree with them). While I took all the pictures as usual, the caption bubbles on a couple of the slides are courtesy of PC World’s art department. Here’s an excerpt from the introduction:

IBM’s Model 5150 PC, released in 1981, was a classic, perhaps the computer most responsible for launching the PC revolution. Sadly, however, its keyboard did not live up to that standard. This 83-key model was IBM’s first, and critics hated it, complaining about its awkward layout and nonstandard design. Stung by the criticism, IBM assembled a ten-person task force to craft a new keyboard, according to David Bradley, a member of that task force and of the 5150’s design team. Their resulting 101-key design, 1984’s Model M, became the undisputed bellwether for the computer industry, with a layout that dominates desktops to this day. As we peek under the hood of this legend, you’ll soon see why many consider the Model M to be the greatest keyboard of all time.

It’s no secret that the title “world’s greatest” ultimately comes down to a matter of opinion. Like the 10 Worst PC Keyboards of All Time, many people are bound to disagree. That’s OK. Feel free to share your picks for the greatest (or simply your favorite) keyboard of all time in the comments below.

Timex-Sinclair 1000 Ad - 1982Fabulous secret powers were revealed to me the day I held aloft my magic computer….

The tiny computer you see above originated in the UK as the Sinclair ZX81, a wildly successful build-it-yourself kit computer. Due to strong sales, Timex struck a deal with Sinclair to market a fully assembled version of the ZX81 in the United States. They rechristened the unit “Timex-Sinclair 1000,” and the minuscule wedge became the first PC to sell for under $100 (US) fully assembled.

The diminutive, Z80-based 1000 was severely limited in function by its tiny membrane keyboard, its black & white display, no sound capabilities, and only 2K RAM. Despite that, it sold well in the US thanks to an incredibly low price. These days, Timex-Sinclair 1000s are relatively easy to find, and thanks to their nice shape, they make great doorstops.

Inside a Classic: The TRS-80 Model 100 on PC World

Some of you might remember the Apple IIc teardown I did for PC World back in March. Now it’s June, and my workbench is back in the spotlight again. This time I dissected the venerable TRS-80 Model 100 laptop computer, which happened to turn 25 this year. Below, I’ve posted an excerpt from the slideshow. I hope you enjoy it.

Twenty-five years ago, Radio Shack released the first wildly successful laptop computer in the United States. The TRS-80 Model 100 was simple, rugged, plentiful, and reliable, selling over six million units during its eight-year life span. With ample battery life, light weight (about 3 pounds), compact size, instant-on capability, and a small suite of built-in applications, the Model 100 served as the portable computing workhorse of its day. Bill Gates’ also ranks it as one of his favorite computers of all time, in large part because he and a friend wrote the firmware it uses.

ERA Magnetic Drum Storage Systems - Computer Drum Memory Ad - 1953Click above to see the full ad.

In this week’s Retro Scan, we’re looking way back to 1953. Many computers in the 1950s used monster magnetic drum storage units, like the one you see above, as working memory — ala RAM — until the faster and more adept core memory came along. Using technology similar to a cylindrical hard disk, these beasts were understandably slow compared to their non-mechanical successors.

If anybody out there ever worked with one of these, we’d definitely love to hear from you.

MS-DOS Saves Columbia Shuttle Data

Sunday, May 11th, 2008

Damaged Space Shuttle Columbia Hard Disk Drive

Vintage computing shows up in some of the unlikeliest places. And in this case, it saved the day.

According to a recent Associated Press article, a 340 megabyte 2.5″ Seagate hard drive from the ill-fated space shuttle Columbia survived the craft’s fiery break-up and crash to the earth back in February 2003.

A data recovery service called Kroll Ontrack managed to recover most of the data on the drive, which dealt with an advanced xenon experiment. Oddly enough, Jon Edwards of Kroll credits the formatting and data storage methods of the MS-DOS operating system for allowing him to recover the data:

However, at the core of the drive, the spinning metal platters that actually store data were not warped. They had been gouged and pitted, but the 340-megabyte drive was only half full, and the damage happened where data had not yet been written.

Edwards attributes that to a lucky twist: The computer was running an ancient operating system, DOS, which does not scatter data all over drives as other approaches do.

Three cheers for the FAT file system. I guess that NASA (or the experiment’s designers) kept their drives pretty well defragged.

It’s amazing Kroll recovered any data off of the platters at all, with the drive’s external case scorched, its dust-proof seal compromised, its heads driven into the platter surfaces, and its internal components desoldered by the intense heat.

I’ll wager that the platters were composed of solid aluminum, like hard drives of old. If the disk had been a more recent model — you know, the kind with platters made of glass — the fragile discs might have been shattered from the stress of the explosion and hard landing.

Damaged Space Shuttle Columbia Hard Disk Drive

Researchers recently published the recovered data from the shuttle’s xenon experiment in a science journal, as was originally intended. It’s satisfying that some good science came out of Columbia’s last mission, proving that the crew’s tragic journey wasn’t completely in vain. For that, in a strange and lucky way, you can thank Microsoft.

Steve Wozniak Announces the 2 GHz Apple IIpc

Tuesday, April 1st, 2008

Apple IIpc LogoFor the last two years, Apple co-founder Steve Wozniak has toiled away in secrecy on a brand new computer system, which he announced today in a surprise press release. The machine, sure to stun the computer industry, carries the torch of the classic Apple II computer line and brings with it a massive installed user base. Wozniak calls his creation the Apple IIpc — a fitting name for a modern update of his venerable Apple II design that sports both a 2 GHz processor and full compatibility with all Apple II software and accessories.

In a special email to the vintage computing press, Wozniak laid out the details. “I’m emailing this to you frist [sic] because I know you’re the ones who supported me all these years,” he writes. “After all, I’m counting on you to make this new launch a success.”

A Modern Marvel

Apple IIpcPowered by a new 2.0 GHz 6502-compatible chip from WDC, the IIpc will retain full backward-compatibility with both Apple II and Apple IIgs software. In a further nod to the past, the computer will ship with three Apple II slots (in addition to the three PCI-X slots on the board) and will include user ports for Apple II keyboards, mice, paddles, and numeric keypads. The IIpc will support memory up to four gigabytes, although Wozniak plans on shipping the first model with only 1GB of RAM.

Perhaps the biggest bombshell in this announcement deals with the IIpc’s new 64-bit CPU. WDC, suppliers of processors for the Apple IIc and IIgs in the past, developed a special chip specifically for this project called the W65T64 Terbium Pro. Long thought to be vaporware by the computer press since it had no known application, the Terbium Pro has finally materialized, although it’s still in the late prototype stages.

“I’m extremely pleased with WDC on this project,” Wozniak writes. “Unlike modern emulation methods, the W65T64 runs Apple II code natively at 2.0GHz, along with more advanced software.”

The IIpc was initially designed as a drop-in replacement for the Apple IIe motherboard, but Wozniak soon realized that the antique IIe case and power supply would severly limit his design’s capabilities. He has commissioned a completely new all-in-one case from Jerry Manock specifically for the Apple IIpc. Manock, an Apple veteran, previously designed the Apple II, Apple III, and Macintosh cases. “Jerry and I work together like magic,” writes Wozniak, “and he’s got an incredible design for a new case that we’ll be testing soon.”

Apple’s Take

Apple Computer LogoSo what does Apple, Inc. and Steve Jobs think of all this? “Every time I talk to Steve, he tells me they still receive over 5,000 calls a day at Apple asking for an upgrade to the Apple IIe,” Wozniak writes, “So he’s happy that I’ll be getting them off his back.”

In exchange for permission to use Apple’s trademarks for a limited-run, limited distribution project, Wozniak had to sign a contract saying that he would handle any and all support issues that might arise. Apple even issued him his own support number, 1-866-866-8668, which satisfies his love for phone numbers with repeating digits.

Regrading trademarks, Wozniak felt it was important to stick to his roots. “I thought I’d stay with ‘Apple II’ as a basis for the name, because my machine is the next step in this long family of computers,” says Wozniak. And what about the model name’s two-letter addition? Wozniak explains: “The ‘PC’ modifier stands for ‘private computer,’ since it’s designed to be used by one person at a time, in other words, by yourself.” He continues,”I though about calling it the “Apple IIrf” — for ‘really fast’ — but I figured people wouldn’t take it seriously.”

Release Plans

Steve WozniakAccording to Wozniak, The Apple IIpc will be available for sale on his website by “fourth quarter 2008” and will retail for $1666.66. But there might be delays. “Aside from the case we’re working on, the W65T64 is really the bottleneck in terms of getting this thing off the ground,” Wozniak writes. “The chip is going into production in June, so until then, I can’t launch.”

Wozniak and Manock formed a new corporation to distribute the Apple IIpc called Wozniock Computers. According to Manock, Wozniak has been waiting years for the opportunity to design something new that people will enjoy. “This is the project that Woz would have worked on at Apple if he hadn’t left the company in 1985,” says Manock. “I really hope people love using it as much as he did making it.”

Inside the Apple IIc

Thursday, March 27th, 2008

Inside the Apple IIcMy trusty workbench has officially gone mainstream, courtesy of PC World. They’ve just published my autopsy of Apple’s first portable computer, the Apple IIc, as a richly illustrated slide show. It’s peppered with factoids and doses of VC&G-style humor, so I think you guys will like it. Here’s an excerpt from the intro:

Earlier this year Apple released its thinnest and lightest portable computer yet, the MacBook Air, to great fanfare. But it wasn’t the first time for such an event: Twenty-four years ago critics hailed another Apple computer–its first portable ever–as a masterpiece of compact industrial design. The Apple IIc marked an important milestone for Apple’s stalwart Apple II line, squeezing the power of a full-size IIe into a svelte 7.5-pound package.

With that intro in mind, I have a question for my keenly intelligent, historically-minded readership: Which release made more of a splash? The Apple IIc or the MacBook Air?

Steve Jobs Signed My Macintosh

Steve Jobs Signature on Inside of Mac Plus Case

Steve Jobs, the CEO of Apple, Inc., signed my Macintosh. And if you’re the owner of a Mac 128k, 512k, or Plus, he signed yours too. In fact, so did Woz.

Macintosh Case SignaturesIn crafting the original Macintosh, Steve Jobs viewed himself and his team as artists. As such, it was only fitting for the renegade band of Apple developers to sign their work. At the urging of Jobs, the Mac design group held a small party on February 10th, 1982, during which they ate cake, drank champagne, and took turns signing their names onto a large piece of paper (see image, right). Soon afterward, Jobs had the signatures engraved into the Macintosh case mold, with an obvious result: Apple permanently impressed the team’s autographs into the plastic case of every Mac that rolled off the production line.

You might notice that some of the signatures present on the original signing sheet are missing on the Plus. But fear not; no one was slighted. All the names originally graced the interior of the first Macintosh release (128k), but according to Andy Hertzfeld, some names were lost over time due to revisions of the case design on subsequent models. For example, compare the Mac Plus interior with this picture of the original 1984 Macintosh case.

I recall seeing signatures in the cases of later Macs by the teams that designed them. But I can’t remember if the later compact Macs contain the original names seen here, or simply others that worked on those particular projects.

Channel Your Inner Jobs

Mac Plus Case Open and Closed

To locate these hallowed names within your own Mac case, simply take your machine apart and peer inside the rear half of its chassis. They might be hard to see at first, but they’re there, hiding in the back. Keep in mind that the presence of signatures on your case doesn’t make your Mac any more or less valuable than it would be otherwise — every early Mac has them, without exception. But at least now you can impress your friends with a formidable piece of Mac trivia.

Shortly after the launch of the Macintosh in 1984, most of its original development team parted company. But in a poetic way, they will always be united inside your Macintosh. It’s a fitting, populist monument to an extraordinary chapter in computer history.

The 10 Worst PC Keyboards of All Time

Friday, November 2nd, 2007

The 10 Worst PC Keyboards of All TimeMy first feature on PCWorld.com is now live — The 10 Worst PC Keyboards of All Time. The article started as a pet project of mine over a year ago, although it took far longer to complete than I expected. Between other projects, I anguished and wrestled with myself over the final ten entries after considering (and using) twenty-plus keyboards in detail. Perhaps I put too much work into it, but I wanted to create the most definitive list I could. The end result will never be truly definitive, of course, since any list like this — by its very nature — is based on subjective criteria defined by the author.

The final work turned out to be much longer than the version published, but the pictures turned out so well (taken by both myself and Steven Stengel of oldcomputers.net), that PC World decided to turn it into a slide show. The result, I think, speaks for itself. Still, an unabridged version might make it to the Net some day, with more info on my ranking and inclusion criteria. Just so you know, I considered only non-laptop QWERTY keyboards that shipped with a computer in the United States for the list.

I’d like to thank Steven Stengel for help with the pictures, and especially Harry McCracken of PC World for doing an excellent job of condensing my lengthy epic for a mainstream audience. Last, but not least, thanks to the PC World staff, who did a great job of putting it all together.

Now that the love-fest is over, you can check out the article here. Let me know what you think. And while you’re at it, feel free to tell us which keyboards you’d nominate for the worst (or the best) of all time.

[ Retro Scan of the Week ] The $129 Dollar Numeric Keypad

Monday, October 29th, 2007
Kensington Macintosh ADB Numeric Keypad

Taking the top prize for most overpriced computer product ever is the “Kensington NoteBook KeyPad.” I actually happen to own one of these, although I picked it up for free at a hamfest. It’s quite honestly nothing special — just an external ADB keypad with a construction similar to any keyboard of the time.

I pose this question to you, dear readers: is any numeric keypad worth $129? Even in 1993? Certainly the Kensington KeyPad’s exorbitant price put it in parity with Apple’s hyperexpensive products in the early 1990s. But why would anyone buy a numeric keypad for the modern equivalent of $186? I suspect lack of competition in the numeric Mac keypad market had something to do with it.
