simpleJ emulates a simplified computer on your PC: a retro-style video game console that lets you understand how a computer works and write your own video game programs. The first microcomputers were quite simple. They had a few kilobytes of memory and couldn't run large programs. Many didn't even have an operating system. Yet they had something valuable: understanding everything about their hardware and software was easy. simpleJ aims to make this possible while running on modern PC hardware.
