Everything for learning assembly language in one pack! emu8086 combines an advanced source editor, assembler, disassembler, software emulator (Virtual PC) with debugger, and step by step tutorials. This program is extremely helpful for those who just begin to study assembly language. It compiles the source code and executes it on emulator step by step. Visual interface is very easy to work with. You can watch registers, flags and memory while your program executes. 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.
