An antique memory-card
(read:canister) used by people before the invention of flash
memory. The canisters held very few images
(twenty-four, or, sometimes, thirty-six), and the only card readers were very expensive, so people usually
had to have the cards
read at Photo-Labs. The process of reading the cards
was called "developing", and only late
in the game would be provided in a digital
you had to scan the photos in from the paper copies.
John: Where does the memory card go in this camera Mom?
Jane: That's a 35mm film camera...
John: What's 35mm film? I've never even heard of that memory card.
