TI-307+ was another "really cheap" calculator introduced in the 1990s.
It followed the TI-307 and its sibling TI-7000.
Compare the unique styling with the TI-1775+ and TI-2200+
introduced in 1996.
Dismantling this TI-307+ manufactured in August 1996 by Nam Tai Electronics, Inc. in China reveals a typical design of the 1990's centered around a single-chip calculator circuit hiding under a black epoxy-blob.
Rather unusual - the printed circuit board (PCB) of the TI-307+ reveals the part number of its main components, obviously a Toshiba T6A73 circuit.
