How can I perform a nonparametric statistical test that is equivalent to a 1 sample t-test?

Question

I have a very small data set, for which I cannot use parametric statistics. I want to compare the median value of a group to 0 (i.e. to determine whether or not the sample median is greater or smaller than 0). For parametric data I would use a 1 sample t-test, but I have no idea how to perform a non parametric equivalent. I would be grateful for any advice on a) which test I could use and b) how I can perfom it (preferably in spss or by hand).

Many thanks!!
