Reverse engineering Prodigy is not without challenges. Though the patent describes the communications protocol and the TBOL language well, it lacks detail of the application protocols – that is, the communications between the Reception System and the server-side applications like Logon, Enrollment, Messaging, and so on.

The progress made last time was to implement the communications protocols and to get the reception system to think it was connecting to the server. Now, we need to move beyond that.

After several months on other projects, I’ve freed up some time, made some significant progress, including successful Reception System login, which I’ll detail below.

Beginning in the mid 1980s, there were a number of online “walled gardens”. Among them were CompuServe, Genie, Delphi, Quantum Link (later PC-Link, AOL, etc), and Prodigy. The latter two were interesting in that they relied on specific client software to access the service.

Quantum Link was certainly novel for the fact that it furnished a graphical online experience for the Commodore 64, and Prodigy was novel for its use of the NAPLPS graphics standard, client-side P-Code virtual-machine, and hierarchical caching. In the early 2000s, some folks nostalgic for Q-Link set out to reverse engineer it, which was a success with Q-Link Reloaded launching sometime in 2005.

It’d be interesting to do a similar thing with Prodigy: To reverse engineer the client and rebuild a mock server with enough functionality to enable those interested to relive another one of the experiences of the early commercial online world. This is the first in a many part series about doing just that.

[ Retro Scan ] DWANGO Online Service

DWANGO Quake Doom Online FPS multiplayer online server Advertisement Scan - 1998Looks real to me

DWANGO, which stood for “Dial-up Wide-Area Network Game Operation,” was an online matchmaking service that specialized in FPS games like Doom and Quake. It has a fascinating history that you can read about more in its Wikipedia article.

I believe I signed up for a free trial of DWANGO circa 1994 so I could play Doom with someone when I was bored, but I don’t remember ever getting it working for some reason. Instead, I often played co-op Doom (and later Quake) modem-to-modem with friends who called my BBS.

Discussion Topic: When was the first time you played a FPS multiplayer online? How did you set it up? (i.e. modem-to-modem, TCP/IP, services like Dwango)

CompuServe Ad - 1988Resistance is futile. (click for full advertisement)

Long-time readers of VC&G may recall me talking about my adventures on CompuServe from time to time. Needless to say, they never looked like this. But I did have a few nightmares featuring enormous floating hive-mind spaceships hooked up to my computer when I was 12.

On second thought, maybe this thing is the machine God uses to create snow — if snow indeed exists.

[ Retro Scan of the Week ] James Bond on CompuServe

Compuserve T-Shirts - CompuServe Magazine 1995The Man with the Golden Gun

I spent more hours on CompuServe in the early 1990s than I probably should have — considering it cost something like $4.80 (US) an hour. But of all the commercial online services at the time, CompuServe’s combination of history (it had been running since 1969), depth, and variety blew the others out of the water. I scanned this particular ad from CompuServe Magazine, which — believe it or not — was one of my favorite magazines back then. Ah, the good ‘ole days.

I’m guessing that CompuServe actually found a member named “James Bond” and got him to pose for this advertisement. He may look harmless, but that gun is filled with instant death acid; it’s one of Q’s new toys.
