TI-1750 looks similar to the 3rd design
but uses completely different components. The Toshiba
calculator chip was replaced with a Sharp
type and the LC-display uses a metal frame. The different position of the
display could be recognized easily due to the asymmetrical display frame.
|The tiny Sharp calculator chip instead the Toshiba chip found in the other designs.|
|The display frame of the 4th design is different from the other designs.|
