You have to convert ta to an (Unsigned)Int8 in order to make it work:
ta = N.array([0, 255, 255, 255,0,0,0], N.UnsignedInt8)
The default integer type is 32 bits signed.

You mean implementing range checking in numarray objects? In my opinion,
that would be a very nice feature, although I don't know how that would
affect the assignment performance.
