1990s Trust Padfighter 250 Wireless Gameing Handsets Midi Gameport Connector.

Bought and used these with the kids in the late 90s but as a good parent I put back in the box when finished with and removed the Batteries.

As I don't have this connector on my pc anymore I can't test fully but putting Batteries in the both still light up

No damage or battery leakage
