Unlike the Mediator 4000D, the Mediator 4000Di is designed to be used with desktop A4000's in their original case. It replaces the original Zorro bus daughterboard. It actually comes in two sections, the first section being the actual busboard whilst the second part is the bridgeboard called the Mediator PCI 40000 which is designed to be plugged into both a Zorro III slot and a PCI slot effectively making them active.

PCI Features

  • 33MHz PCI clock (66MHz with the as yet unreleased SharkPPC)
  • PCI transfers up to 132MB/sec (33Mhz), 264MB/sec (66Mhz)
  • 4GB PCI memory space, accessed through a 512MB window in Zorro III address space
  • Busmastering/DMA in all PCI slots
  • Can use the SDRAM/SGRAM of a PCI graphics card as a DMA buffer
  • Address and data parity control support
  • Interrupt controller (4 lines to each PCI card)
