Welcome to the club...It seems most people start with one computer...when they see it doesn't impact their routine, they start looking to add more CPUs. It's infectious! ( I just spent 2 hours trying to configure an old PIII, but something is stopping it at my router.)
I've run out of computers at four processors, sadly. I might get a Mac laptop added once we replace the motherboard.
Use a shorter cable. When a bit is moving that slowly, they can often die of old-age before reaching their destination. ;^)
Once you get it connected, it's first WU will probably be 2107.</chortle>
