There were several DIFFERENT formats used with these 
standard tape cartridges.  I have some old CDC Patriot tape 
drives that did a serpentine single track at a time format 
on a 3480-compatible tape. I don't think any DEC drive 
supported the 18-tracks-wide IBM 3480 format.  I think DEC's 
drives were also serpentine.  If they are really from an IBM 
compatible system (really too late for 360, most likely 370 
systems) then I think only an IBM-compatible drive would 
read them.  Wikipedia says the 3480 was introduced in 1984.
