    I am looking for an LED (7 segment) style display with 8 digits.

    I am building a GPS derived clock.

    I see there is a MAXIM chip that does this, looking for one built up.

    Farnell have got a couple 4 x 7 segment displays from LED Technology
    pn 5014890 common anode red at $17.20 each , or
    pn 5014920 common cathode green $17.80 each
    They did have more but are not stocking them anymore. These are on stock run-out.

    Tenrod in Sydney have some in various sizes (0.244",0.4" and 0.56")
    and wavelength.

    Rockby have 4x7 red Sharlight CM4-5655 F for about a dollar each
    in their surplus section.

    You will have to use multiple displays and put them together.
    I once had a 6 digit clock HH:MM:SS, I was able to light up just one of the
    7 segs at a time at a higher enough rate that the brightness was still good
    to see. This made control a lot easier as I only needed to switch 6 cathodes
    and 7 datalines.
