Microsoft and Apple have their own disk formatting systems, but Apple can read MS-DOS, while Windows cannot read any Apple file systems.

Music nerds will delight in the wealth of inside references and jokes, as when Ms. Starlite refers to 1979 as the moment before Reagan, MS-DOS, acid wash “and Don Henley’s solo career.”

Microsoft has also participated in many April Fools’ Day pranks over the years, including an MS-DOS mobile for Windows Phone and Google insults.

Libraries of Apple II and MS-DOS games have also been retrofitted for browser play.
