USgamer has published a big heaving cover story on Day of the Tentacle ahead of the game's special edition, due for release sometime this month. The article is essentially a giant interview with Tim Schafer and Dave Grossman about the production of the original game as well as the effort of restoring the old assets:
At the time, [LucasArts] had an archive room. They had two full-time archivists, even in the floppy days. And there was a room full of drawers with floppy discs where the game wrapped, and even milestones in between, before the end, you would take it down to Wendy and—they're credited as being the "burning goddesses" in the credits—because they burned all the CDs. It was the burning room. They sat there burning CDs all day long. But, in the old days, there was a whole room, and two full-time positions of archiving stuff.
I feel like there was the feeling at LucasArts, because Lucas himself had that archive, the barn, and that's where all the LucasArts stuff is now, is in the barn at the ranch. So, there was that feeling of, take care of the artifacts of the thing that you're making, because you'll want them someday.
