Which Apple computer model was internally code-named Carl Sagan?

The Apple computer internally code-named Carl Sagan was the Power Macintosh 7100.

The 7100 was part of Apple’s first-generation Power Macintosh family, introduced in 1994 between the entry-level Power Macintosh 6100 and high-end 8100. It used the new PowerPC 601 processor while retaining compatibility with much of the existing Macintosh software ecosystem. The original model ran at 66 MHz; an 80 MHz version followed in 1995.

“Carl Sagan” was one of Apple’s irreverent internal names for the project. The company reportedly chose the name because it suggested the machine would bring Apple “billions and billions,” echoing Sagan’s famous phrase. Sagan objected after the codename became public, concerned that it might imply commercial endorsement. Apple later changed the nickname to “BHA,” then “LAW.”

A common mix-up is the Power Macintosh 6100, whose codename was “Piltdown Man.” The 8100 was “Cold Fusion,” making the three names part of the same early PowerPC-era naming joke.
