Last television using ultra sonic remote

Hey
Late to the thread!
Alls I know is that the RCA chassis CTC-97 has a 2 or 3 button ultrasonic remote. Mine's from 1980. It has been in storage for a few years, after I replaced the delay line and did some other basic chassis work to it. It was a thrift find and made a great pic after some surgery to the circuitry. I had some great screenshots of it, but they are not accessible due to the server crash, and the fact that I delete the 'masters'.
I have never seen any brand tv with an ultrasonic remote control, past 1980.

Contrast this with Zenith and Panasonic. I have owned examples of both with IR remotes from 81 ad 82 respectively. Remember the Panny 19" set with the IR remote which popped into the front of the front bezel? It was a ColorPilot. That was a cool set I shouldn't have trashed. Or the 1981 Zenith 19" with the green LED channel readout and the early 'computer space command' silver remote, which pre-dated the early 80s Zeniths with the yellow LED channel numbers. The latter sets had a slightly different remote and had the controls behind a door which covered the entire right side of the tv's front.

I saw pics of a CTC-97 set that uses a four-button ultrasonic remote with separate volume up and volume down buttons that also control power on and off. Other than the control panel it was identical to my 1978 CTC-88 set.

I've seen three-button electronic ultrasonic remotes from about that era I guess, and I saw a two-button clicker from I have no idea when, but it had the newer RCA logo.

Just recently I saw a pic of a 1984 13" screen Panasonic with a remote slot. Looked a lot like a 19" screen Panasonic we had briefly before I had any control of TVs that were going in and out of my place. Not sure if that had a remote slot though. I'm familiar with both types of Zenith remotes mentioned, I have a NOS silver ultrasonic unit with Space Phone. It was either that or a zoom button I've noticed.
