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.
