The Secret World of Embedded Computers on PCMag.com

You can now buy a $5 pregnancy test that casually wields more CPU power than an Apple II. The Xbox S controller — by itself — packs more raw processing muscle than a SNES.

Those are merely two of the fascinating things you’ll learn if you check out my latest feature for PCmag.com, “The Secret World of Embedded Computers.” It’s a dee-luxe slideshow that reveals computers at the heart of surprising consumer gadgets.

There are also a couple shout-outs for vintage technology in there (not quite as surprising), so the slideshow is at least somewhat VC&G-relevant. Hope you enjoy it.

Do you Collect Software?

Tuesday, November 16th, 2010

Pile of Floppy DisksHere’s a question for my intrepid readers: Do you collect software? Operating systems, applications, computer games, or even image or sound files? If so, do you have a focus for your collection? How do you store it?

I’ve been collecting software for about 17 years. Much of it was once locked into deteriorating floppy disk formats, but luckily I’ve been able to find working disk images of those particular apps and games (say, for the Atari 800 or Apple II) created by others, so not much is at risk of being lost there.

Everything else — all my personal floppy disks, ZIP disks, CDs, and hard drives for Macs and PCs — I long ago backed up to a central file server that uses a RAID 5 array and offsite backup for extra protection. In that collection are the contents of over 30 different PC hard drives imaged and preserved “in state” for research purposes. I keep all the files in place as they were when those drives were in use, because you really never know what you’ll need in the future when it comes to historical research. Many of those files have come in handy already.

I should note that if you have anything backed up on CD-R, get it off now, because I’ve already found CD-Rs from as recent as 2000 that I can’t read anymore. They really are a terrible archival format. The best hope for long-term software preservation (in my opinion) is to maintain a live RAID array of hard drives that you maintain and update over time.

So how do you do it, and what do you collect? I’m interested to hear from you in the comments below.

Gorbachev CompuServe - 1993“Press <CR> for more”

For my sixth grade social studies class, I wrote a report on Mikhail Gorbachev, former President of the Soviet Union. And he really was “former” then — the USSR had fallen apart just two years prior to my report in 1991. For that report — which I ran across recently — I used every resource available to me, including a novel one at the time: Grolier’s Encyclopedia on CompuServe Information Service. My family subscribed to CompuServe — that massive, pre-ubiquitous-Internet dial-up service that cost amazingly large fees an hour — and I loved it.

What you see above is part of the Gorbachev encyclopedia entry in the form of a dot-matrix printout from the DOS version of CompuServe Information Manager (a front-end client for CompuServe) that I printed myself. Various lines are crossed out and underlined, noting areas of interest that I was to paraphrase for the report. This wasn’t plagiarism — I even cited the online encyclopedia in my report’s bibliography. That fact is actually kinda impressive to me in retrospect.

CompuServe’s online encyclopedia was amazing at the time (1992-1993 era). It was so easy to just search for a term, look it up, and print it out. It sure beat our family’s musty 1968 World Book Encyclopedia set that I used for every report prior to this one (yes, the information in my reports was often woefully out of date). For Christmas 1993, my dad bought us Microsoft Encarta on CD-ROM, and that served as the meat of my school reports for the next few years after that. But that’s another story entirely.

IBM Writing to Read Journal 5

Periodically, I visit my parents’ house and pick through the material vestiges of my childhood. Old toys, broken knickknacks, and drawings rendered in crayon litter their dusty attic. My mom, being the mother she was, tucked them away as small monuments to her child’s journey through life. I’m happy she did.

During one of these visits in 2008, I ran across this curious artifact of my early education. It’s one of my kindergarten spelling workbooks, still filled out in my meandering 5-year old hand all these years later.

As I flipped through its pages, memories of my kindergarten year — 1986 — began to bubble up from the deepest corners of my brain. I remembered the workbook’s contents surprisingly well: it contained simple words with letters omitted, replaced with blanks in which I scrawled awkward glyphs.

I recalled having my spelling knowledge put to the test on primitive PCs of the day, which I had always assumed were Apple IIs in retrospect. But when my eyes fell upon the famous IBM logo printed on the cover, a strange realization washed over me: IBM taught me how to read.

[ Retro Scan of the Week ] AT&T VideoPhone 2500

AT&T VideoPhone 2500 Page in 1992 Sears Wishbook - 1992“Discover a new way to ‘Reach out and touch someone!'”

AT&T launched the VideoPhone 2500 in 1992 with high hopes that it would finally bring video calling to the masses. Ultimately, it fared no better than AT&T’s previous attempts at commercial video phones, all of which exited the market quickly after their introduction.

For $1599.99 ($2,486.19 in 2010 dollars), you received a single phone unit that could send audio and color video (at up to ten frames per second) simultaneously over a regular phone line. It worked its magic through a 19.2 kbps data stream, which is minuscule by today’s standards, but was state of the art in 1992. Unfortunately, the video functionality of the VideoPhone 2500 was useless without another $1599.99 phone to interact with — perhaps the fatal flaw in AT&T’s plan.

[ Retro Scan of the Week ] Sony Digital Mavica FD-7

Sony Digital Mavica FD-7 with Floppy Drive Ad - 1998“It’s as easy as a floppy.”

The Sony Digital Mavica FD-7 seemed so exciting back when it was new, and I wanted one. Its attractiveness stemmed from the cheap and familiar media it used for image storage: standard 3.5″ floppy disks. Most digital cameras of the day required expensive, obscure flash cards for storage and proprietary software to extract photos from the camera (through a painfully slow serial cable). With the FD-7, one needed only to insert the image disk into one’s computer floppy drive and copy the pictures off. But the technological price of this convenience was high: the camera’s maximum image resolution was 640×480 — anything bigger, and you’d only be able to fit a couple photos on a single 1.4 megabyte disk.

Funny enough, I recall ghost enthusiasts on the Internet circa 1998 picking the FD-7 as their camera of choice for its uncanny ability to capture vast flurries of out-of-focus dust (aka “ghost orbs”). That endorsement alone speaks volumes about the camera’s lackluster optical qualities. Also, this new breed of digital ghost hunters didn’t have to feel guilty about taking endless rolls of 35mm dust photos, which can get quite expensive to develop.

[ Retro Scan of the Week ] Apple II Newspaper Ad

Apple II Newspaper Ad - 1982Computers? What is the world coming to?

Here’s another item from my grandmother’s cedar chest — I love these old newspaper line-art illustrations. ECS was Oak Ridge, Tennessee’s first retail computer store, if I recall correctly from an old article I read. They advertised quite a lot in the local newspaper, including the ad for the Apple II you see above.

The Apple II’s configuration with two Disk II drives and a small monitor on top is interesting. I believe I’ve seen Apple promotional photos from the early Apple II days with the same setup. The relatively tiny display seems somewhat silly from a modern perspective, but computer monitors were very expensive back then. A large one that would have covered the entire top of the Apple II would have cost $400 or more in 1980-ish dollars.

In fact, just perusing some ads in the back of a 1981 BYTE magazine, I don’t see any monitors offered larger than a 13″ color Zenith for $399.95 ($933 in 2009 dollars). 9-inch to 12-inch monochrome monitors cost anywhere from $150 to $260, which is equivalent to $350 to $606 in 2009 dollars. You get the point — even entry-level displays back then cost an arm and a leg. Even if you paid two arms and two legs, the monitors were still relatively small.

TRS-80 Pocket Computer  PC-4 Ad - 1983The iPhone has nothing on this. (Click for full advertisement.)

Here we see the state-of-the-art in 1983 pocket computer technology, the TRS-80 PC-4. I have the PC-1 in this series, and it still seems advanced. How many other pocket calculators allow you to program in full BASIC?

I remember taking my PC-1 to high school in the mid-1990s and programming on the sly in my ELP class. It felt so high tech — and my model was made in 1980! Ah, those were the days.

How Times (and Cameras) Have Changed

Digital technology has transmogrified today’s consumer cameras into tiny, futuristic-looking gadgets. Notice how nobody holds them to their face anymore — they just stare at LCD screens.

Not only have the cameras changed, but the photographers have changed as well: it seems that everyone has an imaging device in their pocket these days. With the help of a blog, flickr account, or YouTube, ordinary people on the street often beat professional photojournalists to the punch when it comes to breaking news.

Of course, press photographers still exist in 2009, and their cameras are much bigger and more professional-looking than those seen here. I was just struck by the contrast between the flashbulb-slingers of old and the average citizen photographer of today.
