The iconic '''Nintendo Family Computer''' (Famicom, ファミリーコンピュータ, HVC-001) is a foundational 8-bit console. Most surviving units are now 35–40 years old, and face risks from aging capacitors, brittle plastics, and unreliable power supplies. | The iconic '''Nintendo Family Computer''' (Famicom, ファミリーコンピュータ, HVC-001) is a foundational 8-bit console.
