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+.

Dismantling this TI-808 manufactured in December 1987 by Compal Electronics in Taiwan reveals a surprise: The printed circuit board (PCB) of the calculator is labeled (TI-)508(-11). Not very helpful because the original TI-508 appeared on the market about one year after this TI-808.

Texas Instruments changed within one year the color of the key legends - don't miss the revised TI-808 and a TI-808 in a white housing with blue accents.
