Well, that's not a plain 16-bit application, it's a 32-bit protected mode program. I've re-compiled the sources from this thread (http://masm32.com/board/index.php?topic=1418.msg14444#msg14444) with gcc and jWasm for DOS. That's the output under FreeDOS running inside VMware Player:

Some test results under other environments would be fine.
