Written by Marion Stubbs, published by Quicksilva in 1983 for the Sinclair ZX-81. Also known as "Pioneer Trail".
As a covered wagon party of pioneers, you head out west from Independence, Missouri to the Willamette River and valley in Oregon. You first must stock up on provisions, and then, while traveling, make decisions such as when to rest, how much food to eat, etc. The Oregon Trail incorporates simulation elements and planning ahead, along with discovery and adventure, as well as mini-game-like activities (hunting and floating down the Dalles River).
Currently, emulation for this item does not auto-start. To load the 'cassette' this program is located on, press the following keys: j (which will appear as LOAD), shift-p shift -p (Which will appear as double quotes) and then ENTER/RETURN. Then press SCROLL LOCK on your keyboard, and the F2 key. If all is working properly, the system will bring up a box showing the cassette tape loading into memory. It will stop when complete and the emulation can be interacted with normally. Some games will run by themselves after cassette loading, while others can be started by pressing the r key and ENTER to run.
