Once you use a SuperCPU you will never want to use your 64 without it.
Comes from my personal collection. One of my prized pieces, a CMD SuperCPU64 Rev. 2B with 16MB SUPERRAM! Functions perfectly and looks fantastic! I hate to sell it but I am listing several of my personal items to make room for more!
Because of the age of this item I can offer no exchange or refund.
