The table at the bottom of page 2 and the schematic near the top of
page 3 show ground as being pin 19. The problem be that the pin 19
row of the table slopped over to the next page -- sorry about that.
(I'd kill for a "keep this table together" setting in Word). (02)

Your're right, we could have done that too. But we had someone who
was willing to build the cable, and it seemed like a cable would let
us go faster for multiple keysets, and also test without having to
handle the connectors as much. Besides, there's the "cool" factor,
as well as some poetic justice, in actually using a Xerox keyset to
control NLS. (04)
