StampII data storage question

I am designing a Stamp2 based GPS data logger which will collect data every
6 minutes for up to a week. I have calculated that I need to store 60 bytes
every 6 minutes which calculates out to 60*10=600 bytes/hour or 600*24=14400
bytes/day or 14400*7=100800 bytes/week. I would like to store the data in
non-volatile flash memory. Does anyone have a workable idea as to how I can
store at least this much data?

Any advice/ideas would be appreciated

TIA

Vic

    What type of GPS are you using ?
    Do you already write the code to comunicate with the GPS ?

    Vic,
    Parallax provides a product call StampMEM that can handle this job. It is a
    serial eeprom storage system that uses one pin on the stamp. It will hold
    65,000 bytes which is near your requirement.

    Check out Microchip's I2C 24LC256 Serial EEPROMS. These are 32Kbytes each and
    you can put 8 of them on the same 2 pin bus. If you wanted more storage, you
    could put 8 more on 2 other pins.
