Picked up a calculator at the dollar store a few days ago, and its red color inspired me to draw up this design. I’m surprised Texas Instruments doesn’t already offer this, because the Speak & Spell toy is an 80’s icon.
For a more conventional layout I placed a solar panel where the original Speak & Spell display used to be. The new display fills up what used to be the handle.

Great idea about the Passenger Eject Button…just for laughs. Is this available for purchase yet?
