But the 9114 was a disk drive, wasn't it? (the HP-IL drive for the
71/75/etc). And the 9100 was a calculator (HP's first desktop calculator,
released in 1968, and rather nice).
Yep. Which just goes to show one point I had in the back of my mind
at the time: HP's model numbering scheme comes maddeningly close to
making sense.
