The TI-1626 here is really small, only slightly bigger size than a credit card. I put a penny beside it to convey how small it is.
It's interesting to note that the display is almost exactly the same size as the solar panel next to it!
You can see on the back there's a lack of a serial number, but that this calculator was released in June 1985.
Taking the 1626 apart, which has no screws but rather small snaps holding it together, you see the keys are a whole rubber sheet.
Unfortunately, there's no markings on the main CPU that identify it. All in all, minus the absurdly small size of the calculator,
there's not too much to say about it.
