SUMMARY: Restore OS; make tape device

I wrote, thinking that I had errors when using MAKEDEV to make the rz and tz
devices needed for restoring the OS from backup. As I learned from quite a
few of you, the list that ensues after issuing MAKEDEV is not an error; it's
a list of the devices crated. It's a Good Thing.

I had some extra help learning what tape devices to make. As Javier Aida wrote,

At the console prompt, I did a >>>show device. Seeing that my TLZ07 was on
MKA500, I knew to use # ./MAKEDEV tz5.

Thanks to all who replied. This list is a fabulous community!:
