For convenience, RedPower has been repackaged into four modules. All installations need RedPower Core. Logic, Wiring, and Lighting have been packaged as Digital. World, Machine, and Control have been packaged as Mechanical. For use with other mods, RedPower Compat is a new module which includes additional support for cross-mod compatibility.
RedPower is easier than ever to install! Simply install MinecraftForge, and then place RedPower in your mods folder. The same files can be used on a server.
