sharp el8m
This is an early almost-pocketsize calculator (though it used an external power supply). The size of the numeric keys is about 15 mm. The display is built from eight vacuum-fluorescent tubes (*). Unfortunately the power supply (with unknown characteristics) is missing.

The calculator was donated by Mr. J. Franssen
