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.
Dismantling
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.
