[ Retro Scan Special ] IBM Taught Me How to Read
July 11th, 2010 by Benj EdwardsPeriodically, 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 (seen above) 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 ] Rampant Inflation
July 5th, 2010 by Benj EdwardsInside the Amiga 1000 (25th Anniversary)
June 30th, 2010 by Benj EdwardsCommodore first shipped the legendary Amiga 1000 in July of 1985 — twenty-five years ago. In honor of the Amiga’s birthday, I did what comes natural to Benjs of all sorts: I took one apart. And I did it for PC World, making this the tenth entry in my “workbench series” of tech autopsies.
Giving the Amiga 1000 its place in the limelight is only fair because I took apart its arch-nemesis, the Atari 1040STf, back in March (the ST series also turned 25 this year).
I hope you enjoy it. When you’re done, I encourage you — no, urge you — to share your fondest Amiga memories in the comments below.

Here are my previous workbench teardowns, if you’re interested: Atari 1040STf, Atari 800, Commodore 64, Nintendo Game Boy, Nintendo Famicom, Apple IIc, IBM Model M Keyboard, TRS-80 Model 100, and Macintosh Portable.
Mr. Wizard Explains the Atari 1200XL (Somewhat Badly)
June 29th, 2010 by Benj EdwardsYou remember Mr. Wizard’s World, right? It was a light science show for kids that aired on Nickelodeon in the 1980s. On one episode, Mr. Wizard took a peek inside the Atari 1200XL with his usual juvenile accompaniment. Here’s a clip.
The real fun begins as Mr. Wizard tries to explain the function of a row of eight chips on the motherboard around 1:40 into the segment. He quickly lapses into apparent nonsense:
You see these eight all here? This is an eight bit computer. You’ve heard of that? OK. Each one of these sends a, uh, byte off to the screen and, uh, each little dot has to have a signal from each one of those.
I probably don’t have to tell you this, but that’s not how the Atari 1200XL works. This is Internet, though, so I’ll explain it. Those eight chips are RAM chips, and their exact quantity in any computer is mostly independent of the CPU’s word size (i.e. 8-bit, 16-bit).
The fact the Atari’s CPU is 8-bit and that it contains eight RAM chips is a coincidence that apparently confused Mr. Wizard. The 1200XL had 64KB of RAM, so those are likely 8KB chips (8KB x 8 chips = 64KB). To make up the same amount of RAM, Atari could have used (for example) four 16KB chips or sixteen 4KB chips.
The rest of his explanation for those eight chips doesn’t make any sense either. But hey, it’s Mr. Wizard! Other than that, he does a pretty good job showcasing the 1200XL in a kid-show context. The joystick-sans-stick demonstration is classic Mr. Wizard fare — he’d always change things around and make you think about an issue in an unexpected way. That was his genius.
I loved Mr. Wizard’s World dearly as a kid. In fact, I learned many basic physics principles from that show. We could really use someone like him again.
P.S. If you like Mr. Wizard as much as I do, watch him on The Late Show with David Letterman in 1982.

[ Fuzzy Memory ] Interactive Comic Book

Every once and a while, I receive emails from people looking for a certain game, electronic toy, or computer from their distant past. I then pass it on to intrepid VC&G readers to crack the case.
The Clues
Jim writes:
Let me start by saying how wonderful your site is. Sure does bring back a lot of memories, thanks.
The game I’m looking for was played on my C64 (maybe the 128, but pretty sure it was the 64). The time period was the late 1980’s. I remember the game being called an “interactive comic book”. You played the game by being one of the 3 (I think this is the number) main characters in the book. Depending on what you did, the other characters would react to your actions. You could also “switch” to any of the other characters and play the game from their positions.
Kind of a vague description, but that’s about all I can remember about the game. I really hope that someone remembers what it is that I’m talking about.
Thanks

[ Retro Scan of the Week ] Tiger Game.com

The original touch-screen game system.
Pop quiz: which video game console first featured a touch screen? (Hint: It’s not the Nintendo DS.) How about this one: Which handheld console first supported Internet connectivity?
Believe it or not, Tiger Electronics — a toy company famed for its cheap electronic games — came in first on both counts with the Game.com in 1997. (Sega Saturn was the first home console to support Internet in 1996).
I was a Game.com early adopter, having bought one close to its release. The wonder of its primitive touch screen alone seemed to make up for its deficiencies at the time, so I was pleased at first. The unit shipped with a built-in version of Klondike Solitaire and a Lights Out game cartridge, both of which showed off the system’s touch capabilities well. But my infatuation with the Game.com turned out to be brief.

[ Retro Scan of the Week ] AT&T VideoPhone 2500
June 14th, 2010 by Benj Edwards
“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.

Discussion Topic of the Week: If you owned an easy-to-use videophone device — and everyone else had one — how often do you think you’d use its video functionality?
