LucasFilm Games in early '90 prepared a wide variety versions of the same game: "The Secret of Monkey Island".
The first DOS version of the game can be played on Hercules Graphics Card with PC-Speaker, final version of DOS SoMI works on VGA PCs with CD. Enhanced "talkie" version was prepared couple years ago using speech tracks from The Secret of Monkey Island: Special Edition.
As a bonus I've also included Atari ST, Amiga and Sega CD versions of SoMI.
