The Central Operator's Keyboard
|
Note lack of any upper-case/lower-case shift which is not needed if
you are using 6 bits per character. And the "Carriage Return" is bottom
left where it is supposed to be...
Also noteworthy is the curious ordering of the number keys (zero is on the left) and the lack of n-Key rollover (e.g. a depressed key blocked any other key from being depressed) which caused a "bouncy" sort of typing style. The rocker switch (lower right) shows that this is a more recent keyboard. It dates from the era when the two separate tubes in the operator's console were replaced by a single CRT. This switch was used to control which which of the two original displays was actually shown on the tube. Return to Home Page |
