Identify this calculator

On the hunt! Haha!
The reason I posted it (as you can imagine) is that I thought the date too early. My first reactions were, "some sort of TI and after the RED LEDs...which made me think after 1980. But, BUT, then again, I remember some tiny LCD machines in 7th or 8th grade--which would be, 79/80....

But just as has been pointed out, it is blurry--which makes it that much more challenging.

Also fun: if the picture really is 1978, it was taken less than 20km from my house at the time. If later, it is 200 km :-)
