Initially (1988–89), the Reatta featured a touchscreen computer interface, marketed as the Electronic Control Center (ECC), that included radio and climate control functions, date reminder, trip computer and user-configurable overspeed alarm, as well as diagnostic access to the vehicle's electronic systems and sensors. Later models were equipped with conventional push-button stereo and climate controls. The new system eliminated the trip computer functionality and the climate control buttons could access diagnostic information, replacing the diagnostic scanner capability formerly provided by the touchscreen.

It was a CRT and it was bright AF at night. I remember getting a bunch of them in at the auto auction in the early 90s. They also had burned in screens by that time.
