TI-808_P1.jpg (581285 Byte)Texas Instruments introduced 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+.

TI-808_PCB.jpg (509180 Byte)TI-808_BACK.jpg (361694 Byte)Dismantling this TI-808 (Second Design) manufactured in December 1987 by Compal Electronics in Taiwan reveals a surprise: The printed circuit board (PCB) of the calculator is labeled (TI-)508(-12). Not very helpful because the original TI-508 appeared on the market about one year after this TI-808.

Don't miss the white sibling of the TI-808 and the first Marketing Sample. Within a few months Texas Instruments changed to a conventional Liquid Crystal Display (LCD) instead of the fancy "dot matrix" display but kept the other internals. We refer to this final edition of the calculator as TI-808 (Third Design).
