Nope, you need to mod it to use without a computer, so unless you have a laptop to bring along with the D8, you will need to have it modded. It is possible to do this yourself using traderdave's instructions. It looks really easy but definitely requires a steady hand, plenty of soldering practice, and of course access to soldering gear. One option is to find a local electronics shop employee to do it after hours. And $275 new is not a good price. If you are dead set on doing this, you can get an unmodded one online for $240 new or less than that off ebay.
