Homework First

The Homework First is a combination lock parental control device for the Nintendo Entertainment System made by SafeCare Products, Inc. of Dundee, Illinois 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. Around 25,000 units were claimed to have been sold.

Reception
ACE magazine panned the device on a conceptual level during their 1989 CES coverage.

Jeuxvideo.com cited the device as one of the first video game parental controls.
