@loke @thomasfuchs Punch card containers hold 2000 cards, a card holds effectively 80 bytes or 80 * 12 bits of raw data. That's 160kB per punch card box of effective data.

A punch card takes about 10% of the space (volumetric wise) of a 360k floppy disk though, making it about 450x less information dense. Storing MS Flight Sim on punch cards would therefore take about 20-30 regular sized houses.
