I do not know how it work but you can navigate on Internet with it.

If you choose : http://google.com

you will see all the text (ascii) into the dos windows and picture will be with the file name. With the arrow you can move in the windows and go over links and pictures. If you choose the links and press ENTER it goes to the page and if you select an image, it download the image to your computer and then you can see it.

It's an old program
