The Mediator 4000D is designed to be used with desktop A4000's which have been towered. For non towered desktop A4000's, please see the Mediator 4000Di. It comes in two sections, the first section being the busboard itself whilst the second section is a bridgeboard which connects to both a Zorro III slot and a PCI slot effectively making them active. It can transfer between cards at up to 132MB/sec and between the PCI bus and A4000 at up to 50MB/sec. All slots support bus mastering and 32bit DMA with a 1GB address space. This busboard is designed to be used with the E/BOX (Power Tower) tower kits.
