To the best of my knowledge (not the map maker): RedPower(wiring, lights, world), IndustrialCraft, Buildcraft, Wireless Redstone, and Advanced Machines.
Note: If you update to 7.0.1, the Advanced Machines blocks (not many) and Wireless Redstone (used for everything) blocks all disappear, ruining everything forever. No explosions at least. Teleport pipes will also lose their data, but there aren't any of those on the map by default.
