Buy This Rare Nintendo Cartridge...TestBrian Ashcraft5/31/13 8:15amFiled to: retronintendofamicomjapankotakueast172EditPromoteShare to KinjaToggle Conversation toolsGo to permalink The Famicom Test Cart was used to, well, test Nintendo's Family Computer. It might be rare, but it's certainly not exciting. Advertisement But it is somewhat interesting! And probably more so for hardcore collectors.

Auctions Japan, someone is trying to unload a Famicom Test Cart for controllers. The opening bid is 120,000 yen or US$1,200. As of posting, there are zero bids, but four days left. Four days, people, four days!
