Adding machine (calculator) - learned to operate this in my office machines class in high school.
Canon TP-8 Vintage Portable Printing Calculator
Tested working (printing function not fully tested as no paper but the head did move across and sound as though it was doing something) but due to age sold as a collectable only. I have been collecting old technology (calculators / computers / curios etc.) for over 30 years and the time has come to thin the herd a little. | eBay!
