The K7, which launched mid-1999, that is _before_ OpenOffice.org even
started, has been discontinued by AMD in 2005.. that is 5 years
_before_ libreoffice was launched, and 9 years before 4.3 was
released.
What compelling reason is there to run the lastest version of a
software on such old architecture ? and even more to the point, what
compelling reason is there to slow down everybody else for that.
