If you are having problems with NumPy and SciPy on Pentium III machines running Windows, please try the newly released binaries:

I used the Python 2.5 binaries (.exe) on my home P3 and all seems well in use. I got no failures of numpy.test() but some warnings and failures from scipy.test(). The failures are listed below. Comment: finding the SciPy binaries is not obvious, since they do not show here <URL:http://www.scipy.org/Download#head-312ad78cdf85a9ca6fa17a266752069d23f785d1> Thank you!
