An expansion bus which is designed to be used with towered A4000's, this does not mean the A4000T. It provides the A4000 with active PCI slots which support DMA and are capable of transferring at up to 50MB/sec with 1.76GB of non bank-switching address space. This busboard requires a Cyberstorm PPC or a Cyberstorm Mk-III as it takes advantage of their local expansion bus.
