The Homework First is a combination lock parental control device for the Nintendo Entertainment System made by SafeCare Products, Inc. of Dundee, Illinois[2] and Master Lock. The lock features a "Self-Setting" combination that attaches to the open bay of a front-loading NES-001 system via a screw hole below the cartridge slot which enables the lock to grab the console like a vise to prevent both the insertion of cartridges and the removal of the device.[1][3] Around 25,000 units were claimed to have been sold.[4]
