Download for Win32 - Win95/98/ME/NT/2000/XP/2003/Windows 7 - Not tested with newer varsions of Windows but it probably works. Also try Linux Wine.

This program does not need to be installed as it makes no regristry changes. Just extract the files into a folder and make your own shortcut to the EXE file. This also allows it to be run from a network share. Copy it to the network once and run it anywhere on the network. One day, all software will be like this. You might need a mapped drive.

This simulator uses assembly code very like the old 8086 processor. The underlying machine code is nothing like the real thing.

This is useful for beginners learning assembly code programming. Students will soon want to upgrade to the real deal.
