Prodigy Reverse-Engineering Tools Released

Tuesday, June 6th, 2017

After promising this for years, it’s time to finally release the Prodigy Preservation Project’s reverse-engineering tools. They’re not much, and they’re written in Python, but this code is the means by which I’ve been extracting fossilized Prodigy pages from STAGE.DAT files for the past few years.

I have been delaying announcing their availability because I was hoping Jim Carpenter, the author of these tools (and my partner on the Prodigy Preservation Project) would have more time to add more functionality and documentation, but he has not made any changes to the code since late 2015.

Yeah, I know that was almost two years ago. I’m sorry — things move slowly in ProdigyLand.

So here it is, everybody. Have at it. I hope you can help us improve them.

Just let me know what you find, and I’ll add it to my Flickr galleries.

GamePro AOL Game Disk Package - 1996click on the image above to see front and back

I’ve previously featured a scan of an AOL CD, but so far I have not ventured into the world of America Online floppy disk packaging…until now. Here is a gaming-centric AOL giveaway disk package — still unopened — which I believe came with an issue of GamePro magazine I received as part of a subscription in 1996.

I love the AOL screenshot printed on the package here (possibly mocked up for marketing purposes) because it offers a rare glimpse into the mid-1990s AOL interface (with a Windows 3.1 window motif), centered on “The Games Channel.” If anybody has a collection of AOL screenshots from the 1990s, I’d love to see them.

[ Retro Scan of the Week ] Gather ‘Round the Videotex

AT&T Sceptre Videotex Terminal TV set-top box online modem - 1983A time when TVs were made of wood and children were not yet rabid.

In honor of Thanksgiving, a holiday which tends to emphasize family, I’ve dug up this AT&T Sceptre Videotext Terminal box art that I captured years ago. Look at those gloriously generic 1980s folks gathered around the TV set.

(I say “captured” for this image and not “scanned” because the image is actually a photo of the side of the box — the box itself is far too large to fit on a scanner. It’s roughly 14″ tall by 18″ wide by 11″ deep, if memory serves.)

Videotex: Smart TV in 1983

It’s funny: I’ve purposely avoided talking about Videotex on this blog for eight years because I was saving up material for a story about Teletext and Videotex. I have bought maybe a dozen vintage books on the two subjects since 2006 and mined news archives for information. But as they say, the best laid plans of mice and men oft go to Disneyland. Maybe I will get around to finishing that piece some day. Probably not.

So here’s the skinny. “Videotex” is the name for a graphical computer communications standard that was designed to display mixed visual and text information on regular TV sets. The idea was that a customer would buy a terminal (such as the one seen here), subscribe to a CompuServe/Prodigy/AOL-like online service, and use the terminal to connect to the service and view the information on their home TV set. Kinda like WebTV before the Web. Heck, kinda like smart TVs before the smart.

Graphically, Videotex used the NAPLPS protocol (similar to Prodigy, which grew out of these commercial Videotex experiments) to quickly transmit graphics to the user’s terminal. NAPLPS saves bandwidth because instead of storing/sending data on every pixel (like a bitmap image), the protocol describes graphics in terms of mathematical geometrical shapes (i.e. “draw a triangle at this location and fill it with orange,” like vector graphics).

By the mid-1980s, Videotex services fizzled in the marketplace. Their failure was likely due to low utility (not very useful), plus high cost of subscription (likely from high overhead on the service’s part in both hosting and creating content), and from competition from much more versatile and easier-to-interface-with personal computers.

AT&T Sceptre Videotex Terminal

And so that brings us to this side box art for a circa-1983 AT&T Sceptre Videotex Terminal. I bought this vintage gadget unopened, new-in-box on eBay for literally $1 plus shipping back in 2000.

The terminal works, but it has nothing meaningful to connect to — after all, the related Videotext service shut down almost 30 years ago. The last time I hooked it up, I believe I tricked its internal 300 baud modem to talk to my PC using a phone line simulator and perhaps even displayed a Linux console on the TV set. But that was many years ago. I also remember that the Sceptre has a horrible rubber IR keyboard that barely works.

One could conceivably create a Videotext simulator, hosted on a modern PC, that would pump NAPLPS graphics into to this vintage beast to bring it back to life. Maybe someone already has. If so, I’d like to know about it.

By the way, AT&T has a really neat vintage Sceptre promotional video on its website. It’s worth a watch.
