Certainly. But GCC doesn't build well at all on such a machine. It
seems to me that the expectation right now is at least a gig or two of
RAM. My machine roughly fits your description except for having 512
meg of RAM, and builds on it are ok only if you avoid Java.

I.e., all non-GHz platforms should be on the obsolete list?
