"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.
Itd 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." ...
