I know I can play Classic 0.30_01c on the official MC launcher, but how do I set it to connect to a server? You can still download the classic server at https://s3.amazonaws.com/MinecraftDownload/minecraft_classic_server.zip so I'm trying to figure out how do you tell Minecraft Classic client (the game launched from the launcher) to connect to a server. When Classic ran on the website, looking at the HTML code showed that there was a param tag in the applet tag, that contained the server address and port. But what is the command line equivalent to passing these HTML applet parameters? Is it possible to do this now? Or is this just one more thing that has become completely obsolete in Minecraft?
