Used Voyager calculators

Voyager was HP's code name for its landscape calculators of the 1980s, launched on September 1, 1981 with the 11C and the 12C. The 15C and the 16C followed in July 1982, and the basic 10C that September. They share one body: a 10-digit LCD across the top, a gold f and blue g shift on every key, a tall ENTER key and three button cells. All are RPN and keep their memory with the power off, which is what the C stands for. The scientific Voyagers were gone by 1989, but the 15C came back twice, as the 2011 Limited Edition and the 2023 Collector's Edition, and the 16C has a new Collector's Edition too, so check which one a listing is.
