is a PCI implementation for connecting PCI devices in Amiga
computers, allowing expansion of Amiga with all kinds of industry
standard hardware products like graphic, sound, network, USB,
TV tuner, ISDN and MPEG-2 hardware decoder PCI cards.
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
1200 in tower case with a 4MB RAM expansion card.
The recommended configuration is: Amiga 1200 in the E/BOX
tower case, any 68060 (or PPC with 68060) turbo card with
64MB RAM, a SharkPPC G3/G4 card with 256MB SDRAM, a Voodoo3
Mediator PCI 1200 LT4 features:
4 PCI slots (PCI 2.1 compatible)
simultaneous use of up to four PCI cards fully assimilated
in the Amiga environment.
66/33MHz PCI clock
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 1200 LT4 allows access to the entire 4GB of the PCI memory
space. Access to the entire PCI memory space is executed through
the 8MB window in the A1200 memory space.
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 1200 LT4 uses part of the graphic card memory
for Amiga system needs. Thus, the entire system gains in effectiveness
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
CPU load whatsoever.
Interrupt controller (4 lines to each PCI card)
The Mediator Interrupt Controller manages four independent
PCI interrupt lines.
PCI 1200 LT4 is compatible with all the major A1200 turbo
Mediator PCI 1200 LT4 is designed for the following turbo
cards: Blizzard PPC/060, Blizzard PPC/040, Blizzard 1260,
Apollo 1260, Blizzard 1240, Apollo 1240, Blizzard 1230 (III,
IV), Apollo 1230, GVP 1230, Elbox 1230 and M-Tec 1230.
Installation is very easy.
Mediator PCI 1200 LT4 and PCI cards in its slots fit perfectly
in the following tower systems: D-BOX
Power Tower, Winner Tower, Infinitiv Tower, EZ-Z4 Tower.
Mediator PCI 1200 LT4 can be also installed in other Amiga
towers though this may require some physical modifications
you can check how to install Mediator 1200 LT4
in the D-BOX 1200 system.
The following PCI cards are currently supported
in Mediator PCI 1200 LT4 :
• Graphic cards,
• Ethernet 10Mbps cards,
• Fast Ethernet 100Mbps cards,
• TV tuner cards,
• Sound cards,
• USB cards.
