This LMC simulator is based on the Little Man Computer (LMC) model of a computer, created by Dr. Stuart Madnick in 1965. LMC is generally used for educational purposes as it models a simple Von Neumann architecture computer which has all of the basic features of a modern computer. It is programmed using assembly code. You can find out more about this model on this wikipedia page.
