A friend who worked on a system with the SMS device software sent this:

They're 3420s with the SMS boxes on top. The SMS boxes were hooked to a 
controller that looked like a console to the 370. The console got tape 
messages and would display which tape volumes were to be mounted on each 
drive.

The picture with a volume named INNPUT is someones idea of a joke, since 
tape volume names were 6  characters. The volumes had to be labeled with 
a utility and JCL had to be written to call for the volume.

The tape label utility was IEHINITT.

Thanks
