Relabeled CDC Keystone 92181?  I'm pretty sure they did call 
logging on these.  Very likely the Keystone was connected to 
a 3B2 that received the data over some comm format from the 
ESS computer.  The data rate was not real high.
But, there may have been other tape drives for other 
purposes (firmware, diagnostics, etc.)
