Wrong! Gaming's old-timers will be tickled to hear that a quest in Tal Bruinen was inspired by a gameplay mechanic from an Apple II text adventure game. A Turbine employee revealed this behind-the-scenes tidbit in a thread about the quest on the official LotRO forums.
The Apple II was the first widely successful personal computer. It had a large library of games, many of which are cornerstones of computer gaming history. You can play a lot of those games in your web browser at virtualapple.org, one of the best online emulators. It has many of the all-time classic RPGs like Ultima, Might and Magic, and Wizardry as well.
