This portable, pen-operated personal digital assistant has a black plastic case and a clear screen. A space for an electronic pen is above the screen, although the pen presently with the device does not fit into the space. The pen can be plugged in to either the left or the right side of the Cadillac.
Below the screen is an Apple logo. A tag on the left of the screen reads: SEUTØ13. A tag on the back reads: SEUTØ13 (/) IC.
The Cadillac is a manufacturer’s prototype of the Newton personal digital assistant – Apple would sell the Newton from 1993 until 1998. This example of the Cadillac was owned by Rodney Sol Furmanski (1963-2009), a mechanical engineer by training who worked at Claris as a test engineer. He used the object to test the Newton operating system.
