Watch The Computer Chronicles Online

Monday, September 17th, 2007

The Computer ChroniclesFrom 1983 – 2002, Stewart Cheifet hosted The Computer Chronicles, a public television show devoted to important topics in the field of personal computing. Now viewers can download or stream 560 episodes of the series on their computers from the Internet Archive, with episodes devoted to everything from the Original Macintosh (1984) to the Y2K bug (2000).

I’ve watched a few episodes myself, and they provide a unique contemporary view into the world of vintage computing when it was still the cutting edge. Many of the episodes are co-hosted by the late Gary Kildall, so you rabid Killdall fans out there will quickly get your fill. Go check it out; I highly recommend it.

Great Moments in Shareware: ZZT

Monday, September 3rd, 2007

ZZT

Read any popular game publication these days, and you’ll probably come across ample mention of Epic Games’ Unreal Engine, the 3D powerhouse behind blockbuster first-person shooters like Bioshock and Gears of War. Believe it or not, one of today’s hottest game engines traces its roots back to a 2D text-based game programmed by a University of Maryland college student during the golden age of shareware.

Tim Sweeney founded Potomac Computer Systems in 1991 with the release of ZZT, a graphical ASCII character-based game that ran on a simple object-oriented platform programmed by Sweeney. With an in-game editor, Sweeney created multiple ZZT episodes that he sold to finance the new company. Luckily, Sweeney didn’t limit the in-game editor to himself; it featured prominently on the title screen of the free shareware edition. Much to Sweeney’s surprise, the editor itself soon became the most popular part of ZZT, allowing players to create their own games in the ZZT engine. Potomac changed its name to Epic MegaGames, and a shareware giant was born.

A large community of rabid ZZT fans still thrives thanks to the Internet, where enthusiasts trade nostalgia, user-made games, and the latest attempts to squeeze every last drop out of the ZZT engine through emergent programming techniques. For example, clever world builders have managed to reproduce just about every major 2D game genre — even genres the engine wasn’t designed for — in ZZT‘s editor, albeit in primitive forms. For modern ZZT fans, the game’s fun lies not only in playing the community’s user-created games, but in the challenge of creating new and unexpected things with a simple set of tools and components.

The original shareware package of ZZT only included one game: Town of ZZT, a whimsical adventure created by Sweeney that calls upon a player’s action and puzzle-solving skills. But in the late 1990s, Epic released all of Sweeney’s classic ZZT episodes as freeware, so you’ll find those worlds in the file below as well, including Dungeons of ZZT.

Have fun. Feel free to share your fond ZZT memories (or latest ZZT exploits) with the rest of us.

(Update – 05/25/2009: If you love ZZT, check out this interview I conducted with its creator, Tim Sweeney.)

[ Retro Scan of the Week ] A Prayer for Computers

A Prayer for Computers

For VC&G’s first dip into the deep, unsteady waters of religion, we have an interesting work of spiritual poetry, “A Man-Made Brain,” that I found in a Goodwill store yesterday. It’s from a book titled Lord, I Want to Tell You Something by Chris Jones (Augsburg Publishing House, 1973), a book of every-day prayers “for boys between the ages of 9 and 13.” I literally picked up the book and turned to this page, so perhaps the Lord wanted to tell me something (“Use This For A Retro Scan of the Week, My Son”). Who am I to argue with divine provenance?

My regards to Jones for his futuristic insight. And for blowing my mind.

[ Retro Scan of the Week ] The HP-150 Touchscreen Computer

HP-150 Touchscreen Computer Ad

In 1983, Hewlett-Packard released what may have been the world’s fist personal computer with an integrated touch-screen. The HP-150 was an 8088-based MS-DOS compatible PC with a handful of advanced features for its time. Unfortunately, the 150’s hardware architecture proved so different that it was not compatible with most IBM PC programs.

The HP-150 uses a crude, low-resolution method for detecting finger placement on its display. The unit projects a grid of infrared beams across the surface of the screen. By sensing which beams are obstructed by an object, the computer can calculate the coordinates of the touch.

Aside from the touch-screen, The HP-150 is notable for being the first U.S. computer to use Sony’s 3 1/2-inch “micro-floppy” disk format, as well as support for Ethernet networking, hard disks, and HP’s first LaserJet printer (through an HP-IB interface). Not bad for 1983.

Anybody have one of these that they don’t want anymore? I’d love to add one to my collection.

[ Retro Scan of the Week ] The 3-Inch Compact Floppy Disk

3-Inch Compact Floppy Disk

Sure, you’ve probably seen plenty of 3.5″ “micro-floppy” disks. But have you ever seen a 3″ compact floppy? I picked up a stack of these at a thrift store about seven years ago. The ones I found were once used with an Amstrad computer (strange to find in the US), which unfortunately wasn’t accompanying the disks at the shop. Amstrad, the once-prominent British computer manufacturer, used these disks in a few of their computer models (the CPC and PCW, or so I read), and consequently, mainstream usage of 3″ floppies was limited mostly to the UK. Sony’s 3.5″ floppy standard took firm hold in the US because of Apple’s decision to use it in the Macintosh.

I’ve seen an advertisement in an old computer magazine for a 3″ 128k compact floppy drive for the Apple II, one of this format’s first applications. Nintendo fans out there might notice similarities between this disk and Nintendo’s 3″ Famicom Disk System media, but Nintendo’s disks used a proprietary format based on a different standard.

A neat history of the 3″ compact floppy disk can be read here.

The History of Civilization now on Gamasutra

The History of Civilization on Gamasutra

Earlier this year, I spent a few months getting into everything Civilization for an in-depth look at the history of Sid Meier’s classic. The result of that work is now up on Gamasutra as “The History of Civilization.” It also includes (at the end of the article) the transcript of a lengthy telephone interview I conducted with Sid Meier on the topic.

I’d like to extend special thanks to Sid Meier, Bruce C. Shelley, and Troy S. Goodfellow for their indispensable help in putting the piece together. I hope you enjoy reading it.

Great Moments in Shareware: Scorched Earth

Thursday, July 12th, 2007

Scorched Earth

Sixteen years after its humble emergence in the golden age of the BBS, Wendell Hicken’s timeless 1991 artillery simulation remains a hallmark in shareware history. Scorched Earth stands as nothing less than a masterpiece in the field of computer games.

With its numerous gameplay settings, variable computer AI, and an impressive variety of entertaining power-ups, Scorched Earth possesses nearly infinite replay value. It’s also one of the greatest party games ever devised: up to ten players can take turns plotting the explosive demise of their closest friends at the hands of a Nuke, MIRV, or Death’s Head over as many as 1000 rounds. As a testament to the pure strategy of the game, veterans skilled in the ways of Scorch know the best ways to dispatch foes — or merely survive as others duke it out — under any circumstance, rain or shine, springy walls or rubber.

Many of today’s game designers seem envious of Scorch’s ability to consistently entertain for over a decade. Fans of Hicken’s classic have attempted modern remakes of or improvements upon Scorched Earth, but to this day, none has even begun to approach the solid feel, intricate balance, or professional production values of the original. That’s how good it is.

Hicken didn’t invent the artillery game; he perfected it. And as long as our computers run without smoking, we’ll still be playing the original Scorched Earth as good Wendell intended.

Scorched Earth 1.5
Release Date: 1991 (1.0), 1995 (1.5)
Author: Wendell T. Hicken (aka “Sprig”)
Platform: MS-DOS
Runs Best On: Any 286 or 386 PC with 640K+ RAM and a VGA card
Notes:
Amazingly, Scorched Earth runs pretty well on modern computers under Windows. If the game seems too fast, adjust the in-game “Firing Delay” setting (under “Hardware”). You might also want to try running the game under DOSBox. The game uses the PC speaker for sound.
