You can sell things at http://www.ticalc.org/buyandsell/index.html Is this the grey cable or the black cable? If it's the black one, keep it. It only works with the 85 and was discontinued by TI years ago. >I have a TI Graphlink cable and software I bought from TI a couple of years >ago for my TI85. I don't have a use for it anymore, so I'm selling it.
