IMPORTANT!!! PLEASE READ CAREFULLY >>> The first time you click the links below, in most cases, the new page doesn't work correctly. Because all the required elements are not yet downloaded. So, after loading them, YOU MUST RELOAD THE PAGE, by clicking the REFRESH button or pressing F5. Then it's ok (at least, I hope so). By the way, all this runs fine with Windows XP, Internet Explorer and a mono-core CPU. But maybe you could give it a try, even if you have something else?
