The creation of the tablet was performed[further explanation needed] by the Advanced Research Projects Agency. The RAND Tablet was one of the first devices to utilize a stylus as a highly practical instrument. [1]
The tablet is connected to an input of a computer and/or an oscilloscope display. The display would register the input and display it on the computer screen.
