A young prospective astronaut is in a classroom, and they're covering Hohmann transfer orbits (and the equations on the whiteboard in the scene are correct!)

The prof asks her for the value of a couple of variables. "Use your calculator!"

And she says, "What the Heck? This calculator has no equals key!"

And they've clearly rendered an HP-41cv.

That scene was very funny Thank you for finding that johnb.
Here is the above described sequence shown in still frames.
