9 Volt Control Centers
The Control Center, released in 1990, was the first computerized
Technic element, although it was available as a Dacta item since 1985.
The control center could accept input from the control panel and had 3 9V outputs for 3 motors.
1 motor was directly controlled by 2 buttons that ran the
it foreward or backward. The other 2 motors were controlled simultaneously
by a 4-position Control pad that had 8 different combinations, resulting in 2-axis control.
2 separate series of keystroke sequences could be recorded then ran as a 'program'.
The 1995 version allowed for the use of a 9V transformer. |
