I have a boxed shrinkwrapped one, It's called the Envisio NDA030, it's a little video-out upgrade made for the powerbook 140 and 170, that plugs into the memory socket, it provides a ram upgrade for the powerbook and the video out. http://calbears.findarticles.com/p/articles/mi_m0NEW/is_1992_Jan_22/ai_11872921
