emu8086 is the emulator of 8086 (Intel and AMD compatible) microprocessor with integrated 8086 assembler and tutorials for beginners. The emulator runs programs like the real microprocessor in step-by-step mode. It shows registers, memory, stack, variables and flags. All memory values can be investigated and edited by a double click. The instructions can be executed in a regular forward direction and also in reverse direction.

emu8086 can create a tiny operating system and write its binary code to a bootable floppy disk. This software package includes several virtual external devices: robot, stepper motor, led display, and traffic lights intersection. Virtually anyone with any programming experience can design animated virtual devices in assembly language or in any other programming language. All devices are open for modifications and cloning (source code is available). All communications between the microprocessor and devices is coming through this file: c:emu8086.io, to emulate in/out instructions it's just required to change corresponding bytes in this binary file.
