@krl @attoparsec No, these were split-flap displays. Plastic flaps with half of a letter printed on each side that were mounted in a quite sophisticated mechanism:

@Habrok42 @attoparsec thanks! I've confused those.

@Habrok42 @krl @attoparsec either that, or they used what was referred to as "glow cube" technology, where a cube with two painted sides (black and neon yellow) was flipped over with an electric motor.

@krl @attoparsec Yep, good ol' noisy af split-flap tech. In this case it's actually a vane display given it's representing a seven segment number, not a flip-dot display.
