On August 21st, you'll have the opportunity to save the world with the same Apple II Desmond used to monitor in The Swan. But don't get mad at me when you fail to contain the magnetic forces building pressure beneath your basement.
This configuration is an Apple-II Plus system running an Apple-III monitor, with a Disk II floppy drive. This same prop is used as both the Swan and Pearl Station computer (as evident by the Swan logo). At the Pearl Station, the computer is connected to a dot matrix printer with the "System Failure" log printout that alerted Desmond to realize what caused Oceanic Flight 815 to crash.
It would be fantastic if I could write MacStories articles on this thing. Though I imagine you'd get tired of seeing 4 8 15 16 23 42 in every other post.
