I was always confused when I saw nostalgia screenshots of Oregon Trail, because they had fancier graphics than the version I remembered. Then I saw this version, which is even older than the one I played. So I searched and found this site with all the versions:

It looks like I played the 1980 version, which at least had a primitive type of graphical hunting.
I attempted to emulate the 1975 version by interpreting the basic as JS. It probably has some issues in the conversion, but it should be more accessible:

It essentially creates a state machine for each line of Basic, and uses a loop as the program counter. going into the appropriate state based on variables.
As usual with browser emulation, iDevice fails to show the keyboard, nor can one copy and paste letters or words in the terminal. Apple's fault. Still cool.
