      11/730 (even later), was a smaller, even slower, further cost-reduced version
      of the same. My recollection is that most of the size and cost reduction was
      accomplished by using more highly integrated gate arrays to replace discrete
      TTL logic chips (which, at the time, were faster than the gate arrays).

      I believe the 11/730 was small enough to be easily rack-mountable, while the
      11/750 occupies most of a short cabinet. I could be misremembering, though;
