  The TU10 DECmagtape unit was available in eight different models. Each model incorporated a transport mechanism, head assembly, read/write electronics, motor control circuits, power supply, and cabinet. Bit packing densities of 200, 556, and 800 bits per inch (bpi) were program selectable. A single capstan drove the tape in the forward or reverse direction at a speed of 45 inches per second (ips).
