If you’re looking for a link cable for TI calculators (TI-86, etc.), I’ve got 7 extra in brand-new condition. Specifically, these are 2 ft cables with a right-angle 2.5mm male TRS connector (“phone plug”) on each end. For those of you looking to use this in an audio application, these are “stereo” cables. Email me. I’m looking to get rid of them, so I’d only be charging to cover the cost of an envelope and shipping.
