TI-1895 Metric Converter introduced in 1984 added solar cells to
the TI-1889 launched already in 1982 and matches
perfectly the design of the TI-1766.
Dismantling this TI-1895 Metric Converter manufactured in April 1986 by Toshiba Corporation in Japan reveals a very clean design centered around a Toshiba T6856S single-chip calculator circuit soldered on a single-sided printed circuit board (PCB) and powered by five large solar cells.
Inspecting the PCB of this TI-1895 calculator brought our attention to a small mark reading TI-1895 21, obviously a reference to TI-1895 and revision 21 (layout) of the PCB. We started compiling a list of the PCB-Marks on calculators manufactured by OEMs for Texas Instruments.
If you are interested in really powerful metric conversion calculators, look for either the Canon FC-80 or the TI-1890.
The TI-1895 was replaced in 1986 with the stylish TI-1895 II.
