This is just to add to others my experience that PowerLogix's new 1.4 GHz 7457-based CPU upgrade does not have the wake from sleep (coma) problem of some previous upgrades (1 GHz and 1.2 GHz) on my Cubes. PL includes a firmware patch that must be applied before the new CPU is installed. See <http://www.macsonly.com/index.html#1261> or after tomorrow <http://www.macsonly.com/arch401.html#1261>. Bill
