Thanks Bobbie for offering to burn a disk of 64 bit Ubuntu Server if that
turns out to be available. If it does and you get it done, is there any
chance I could arrange to pick it up before next Saturday when Jim and I
will be meeting to try to move this project along to whatever the next
hiccup will be. Ron
