Editor note

According to Sierra, the DOS version required for the original (disk version) is literally "DOS". Since DOS 3.0 was the first to use 286 features, I'm using that in this game entry (DOS 6.22 will run on an 8080). The disk versions of the game can officially be patched to be identical to the CD version which required DOS 5.0.
