 Which terminal was it used for originally?

 It appears to be from a 3101?
 
The 3101 has 15 pin DSUB while this has a 25 pin D-SUB. So, while very
similar to 3178 and 3101 keyboards in many aspects I do think it is
different. Maybe some kind of replacement keyboard for the big original
3278/3279 keyboard. Will trace the connections of the cable some day to
verify, though.
