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 Voodoo4
Mediator PCI 1200 TX features:
6 PCI slots (PCI 2.2 compatible)
simultaneous use of up to six 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 TX allows access to the entire 4GB of the PCI memory
space. Access to the entire PCI memory space is executed through
windows in the A1200 memory space. With a MMU supported paging
mechanism, PCI memory access is executed without any slowdown
compared to the linear memory access.
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 six
PCI busmaster cards may be used simultaneously in Mediator.
• SDRAM/SGRAM of PCI gfx card as
a DMA buffer
Mediator PCI 1200 TX 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.
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.
AT and ATX connectors with control IC
Allows to supply Amiga using PC AT or PC ATX power supply.
• Power Management Interface
allows waking up the computer with external events (e.g. with
USB or LAN signals) and programmable shutting down the computer.
PCI 1200 TX is compatible with all the major A1200 turbo card
Mediator PCI 1200 TX 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, Elbox 1230 and M-Tec 1230.
Installation is very easy.
Mediator PCI 1200 TX and
PCI cards in its slots fit perfectly in the following tower
Power Tower, Winner Tower, Infinitiv Tower, EZ-Z4 Tower.
Mediator PCI 1200 TX can be also installed in other Amiga
towers though this may require some physical modifications
you can see the Mediator 1200 TX installed in the
D-BOX 1200 system.
The following PCI cards are currently supported
in Mediator PCI 1200 TX:
• Graphic cards,
• Ethernet 10Mbps cards,
• Fast Ethernet 100Mbps cards,
• TV tuner cards,
• Sound cards,
• USB cards.
