7 track or 9 track? The Univacs are pretty old even for "vintage".

Also, as Dave McGuire noted, a lightly-used tape from a known-good drive 
will be useful. In the floppy-disk world, I use several diskettes each 
from a known good drive to validate "alignment".

Seems to me, there's likely several boxes of mag-tapes in the inventory.
