Since 1982 when I bought Chuck Peddle's Sirius 1 (Victor 9000 in the US), I have had the following failures: power supply: 1 hard disk drive: 4 modem: 1 (lightning) I've been building my own machines for a number of years, and have generally had more disks than power supplies. At the moment, for instance, I am running 1 power supply, 1 CPU and 6 disks, so my odds in favor of a disk failure as opposed to a power supply failure are significantly increased. Your response was interesting, alvin, thanks. -- ....................paul "The number of UNIX installations has grown to 10, with more expected."
