I remember having something like that only smaller to take a Polaroid photo of a small o-scope screen.

I remember doing similar with an original IBM PC for some early “computer art”. Had to turn off all the lights, and position a long-lens camera down the hallway to minimize screen curvature artifacts. Printing “screenshots” looked nothing like what was actually on the screen.
