Our 360/50 had 2400 drives.  Read both 7 and 9 track on one.  I think 
the subsystem was structured similar to the 3400 which had a controller 
box that powered and ran the drives.  I'm not sure what the 2400 system 
number was, but the 3400 series was a 3803, I think with the power 
supply and channel, etc.
