Hello, We have a used TI-82 (ROM Version 18.0) for sale. Comes complete with the Guide Book and the link cable. We plan to sell to the best offer. You may inquire on the CALC-TI list, but to avoid unnecessary band-width usage, it may be wisest to send your inquiries to me by private e-mail: maryesme@3-cities.com. Sincerely, Mark :)
