Rott mapper deluxe

[codingnation]

Hello, Im new to the forums. I have a question regarding an old editor for an old game like Rise of the Triad, called Rott mapper deluxe. It's from 1996 i think, and was distributed as a shareware. Does anyone know if it's still possible to purchase that editor, and if so, from where? I would like to buy a registered version so as to have the fully working editor.

thanks
