Emu8086 - Microprocessor Emulator Description:

Emu8086 is extremely helpful for programming in assembly language. The source code is compiled by assembler and then executed on Emulator step-by-step, allowing you to watch registers, flags and memory while your program runs. Complete 'all in one' solution for coding in Assembly Language.

Arithmetic & Logical Unit (ALU) shows the internal work of the central processor unit (CPU).

Emulator runs programs on a Virtual PC, this completely blocks your program from accessing
real hardware, such as hard-drives and memory, since your assembly code runs on a virtual machine, this makes debugging much easier.

8086 machine code is fully compatible with all next generations of Intel's micro-processors, including Pentium II and Pentium 4, I'm sure Pentium 5 will support 8086 as well. This makes 8086 code very portable, since it runs both on ancient and on the modern computer systems. Another advantage of 8086 instruction set is that it is much smaller, and thus easier to learn.

Everything for learning assembly language in one pack.
