Technic Control Center
The Lego Technic control center (1990) was the first programmable standalone Lego product, by the sense of being able to store sequence-based programs and run them. It featured three output ports and manual control, and it was only capable of storing linear sequences of manual input plus timing information. It could store up to two programs at once.
The manual controls could be used to independently control the three motors. To record a program; the controller had to be put in programming mode, and then any manual cotrol would be recorded to the program. Pauses could also be included in a program. When the recording was done, the controller could successfully recall and execute any manual action done during the recording. The executing program could be set to loop infinitely.
Compared to the later programmable controllers, the Technic control center is extremely simple and can only barely be called programmable.

Famous quotes containing the words control and/or center:
“The three-year-old who lies about taking a cookie isn’t really a “liar” after all. He simply can’t control his impulses. He then convinces himself of a new truth and, eager for your approval, reports the version that he knows will make you happy.”
—Cathy Rindner Tempelsman (20th century)
“Columbus stood in his age as the pioneer of progress and enlightenment. The system of universal education is in our age the most prominent and salutary feature of the spirit of enlightenment, and it is peculiarly appropriate that the schools be made by the people the center of the day’s demonstration. Let the national flag float over every schoolhouse in the country and the exercises be such as shall impress upon our youth the patriotic duties of American citizenship.”
—Benjamin Harrison (1833–1901)
