The TI-5000 started in 1982 a new generation of miniature printing calculators. At first glance the TI-5000 remembers the TI-1766 developed and manufactured by Toshiba in Japan. We notice similar keys, similar coloring of the housing and an identical text font.
the TI-5000 reveals indeed a masterpiece of Japanese engineering, probably from
Toshiba. The internal construction and layout of the components looks even 20+
years after its market introduction perfect to us.
The printed circuit board (PCB) of the TI-5000 is populated with a single-chip calculator circuit manufactured by Toshiba, the LC-display and a small single-inline printer driver.
The thermal printer was manufactured by EPSON, Japan and found its way in other calculators like the TI-5008 and the rare TI-45 MSP.
