DescriptionObject is a large beige box that seems to be two boxes joined at the center. Seen from the front, the left cubical section has the A22 model number; this is the control unit. It contains a large swinging gate of circuit cards that opens to the rear. The right cubical section is the model B22 dual tape drive. (Additional B22s could be added.) At the front of the right section two small doors flip up to reveal insertion areas for tape cartridges.
The IBM 3480 line were tape drives that used a new, 5.5-inch square tape cartridge that provided higher density and easier storage than the old 10-inch round reels. http://www-03.ibm.com/ibm/history/exhibits/storage/storage_3480.html (retrieved 29 July 2015).
