That's my point - with ROM A05 and Wm 2003, 1.5 greatly increases nps over 1.4 on PPC 2002 and ROM A01 -- do you have Cg 1.5 ? - it has nps option runs some tests and we can compare. Seeing is believeing. If you have CG, Richard has a special version of 1.4 that has nps in hex format . email him for the test copy. > >Michael > > >Michael
