For those who remember the old days of Apple, where a rainbow colored fruit was their logo, there is now a chance to reminisce in a new way.  The source code of version 3.1 of Apple DOS was released.

As reported by The Register, there’s over 4,000 lines of code.  More information as available through the Computer History Museum and Paul Laughton, the developer of the operating system.
