Thirty Years of Backwards Compatibility

Eric Lippert, who works on the Visual Studio Tools for Office team at Microsoft, has a great blog entry showing how the error codes and descriptions for VB6 and VB Script go all the back to the original Altair BASIC  (Microsoft's first product) written by Bill Gates and Paul Allen back in 1975 for the Altair 8080.

Who says Microsoft doesn't maintain backwards compatability ?!
