Instruments introduced this rare TI-2130 with a foldable housing already in 1984.
This approach gives a calculator with the size of a pocket calculator but a keyboard like a desktop calculator.
Dismantling this TI-2130 manufactured in September 1985 by Inventec Corporation in Taiwan reveals a very interesting approach. Please notice the hinges between the two parts of the housing and the flexible electrical connection hidden by a black tape between them. The later TI-1775 makes use of a much simpler construction.
