Texas Instruments introduced in 1986 with the TI-808 a small desktop calculator with a dot matrix display. It looks today like a marketing gag, neither readability nor design of the numbers was enhanced to standard calculators like the TI-1795+. While the TI-808 (Second Design) changed in 1987 the color scheme of the calculator, switched this TI-808 (Third Design) the Liquid Crystal Display (LCD) to a standard product with actually superior contrast.

 Dismantling this TI-808 (Third Design) manufactured in October 1988 by Compal Electronics in Taiwan shows that only the LC-Display was redesigned, the printed circuit board (PCB) of the calculator is still labeled (TI-)508(-12).

Don't miss the white sibling of the TI-808.
