Homework First Combination Lock NES Cartridge Slot
No, ‘Homework First’ isn’t a joke, but a real Nintendo Entertainment System (NES) lock released by Master Lock back in 1990. It’s designed to thwart kids from playing video games before doing their homework by locking the cartridge slot. That’s right, it attaches to the open bay of a front-loading NES-001 system via a screw hole below the cartridge slot.



Once attached, the lock grabs onto the console like a vise to prevent both the insertion of cartridges as well as the removal of the device. We don’t know the exact number produced, although Master Lock claims that approximately 25,000 units were claimed to have been sold worldwide. This all happened before the internet became a thing, so all the press came from its 1989 Consumer Electronics Show (CES) appearance. Want one for nostalgia or collecting purposes? There have been three recent sales on eBay that have ranged between $45 – $133.50 USD, depending on their condition, so you’ll have to keep a close eye daily or setup an alert to snatch the next one available.
