This is the classic version of The Oregon Trail that launched the second generation of the game. When you arrive at this website, look for the “Load” buttons, which are marked with file folder icons. First click the “Load” button for Drive 1, then choose “Educational”, and then “Oregon Trail – Disk 1”. You should also load Disk 2 to Drive 2, or else you will need to change to Disk 2 when you get halfway to Oregon.
