Mediator is a PCI implementation for connecting
PCI devices to Amiga computers, expanding the Amiga with all
kinds of industry-standard hardware products like graphic,
sound, network, USB, TV tuner, ISDN and MPEG-2 hardware decoder
Moreover, the Mediator PCI busboard is ready for SharkPPC
PCI cards based on the latest PowerPC G3 and G4 processors.
The minimum hardware configuration is: Amiga
4000D in the standard desktop case.
The recommended configuration is: Amiga 4000D in the standard
desktop case, any 68060 (or PPC with 68060) turbo card with
128MB RAM, a SharkPPC G3/G4 card with 256MB SDRAM, a Voodoo3
The Mediator PCI 4000Di features:
4 PCI slots (PCI 2.1 compatible)
simultaneous use of up to four PCI cards fully assimilated
in the Amiga environment.
3 Zorro III/II slots
simultaneous use of up to six Zorro III/II cards.
33MHz PCI clock (66MHz with SharkPPC G3/G4)
the PCI clock running at 33MHz, data transfers are executed
with the bandwidth of up to 132MB/s and up to 264MB/s for
32-bit PCI datapatch
Longword transfers are supported in all data transfer types:
PCI to Amiga, Amiga to PCI and PCI to PCI.
4GB PCI memory space
PCI 4000Di allows access to the entire 4GB of the PCI memory
Busmastering/DMA in all PCI slots
PCI supports the busmastering mechanism in all its PCI slots.
The PCI cards in the busmaster mode can offer extremely fast
DMA access (up to 132MB/s) without any CPU load. Up to four
PCI busmaster cards may be used simultaneously in Mediator.
• SDRAM/SGRAM of PCI gfx card as
a DMA buffer
Mediator PCI 4000Di can use part of the graphic card memory
for Amiga system needs. Thus, the entire system gains in performance
as graphic card's SDRAM/SGRAM memory modules are about 10x
faster than FastRAM memory in Amiga turbo cards. With very
short access time in SDRAM/SGRAM, several PCI busmaster cards
may use this memory simultaneously. The PCI cards may then
rush at the data transfer rate of up to 132MB/s without any
• DMA to A4000 motherboard space
Mediator PCI 4000Di includes a busmastering controller supporting
transfers between PCI cards and the A4000 motherboard space.
Address and data parity control support
and data parity are supported in all Mediator slots. Parity
support is necessary for using PCI cards like Sound Blaster
Audigy, Sound Blaster Live! or ForteMedia FM801-based PCI
Interrupt controller (4 lines to each PCI card)
The Mediator Interrupt Controller manages four independent
PCI interrupt lines.
PCI and Zorro
Mediator PCI 4000Di enables
simultaneous operation of up to four PCI cards and up to three
Zorro III/II cards.
PCI 4000Di is compatible with all A4000 processor card models.
Installation is very easy. Simply replace the original Commodore
A4000 Daugther Board with new Mediator PCI 4000Di.
Mediator PCI 4000Di, PCI, Zorro III and Zorro II cards in
the slots fit perfectly in the standard A4000 desktop case.
- Mediator 4000Di
- with Fast
Ethernet PCI card,
Fast Ethernet, Voodoo 4 and TV tuner cards.
