Zorro Extenders & Busboards
Elbox: Mediator PCI 4000D
Connection: Other |
Closeup of Busboard - 164K
Another Closeup of Busboard - 92K
Zorro II: | None | |
Zorro III: | 7 | (1 is reserved for bridgeboard) |
ISA: | None | |
PCI: | 6 | (Active, 2.1 compliant, 33Mhz, 1 is reserved for bridgeboard) |
Video Slots: | 1 (inline) | (AGA type) |
Other: | None |
The Mediator 4000D is designed to be used with desktop A4000's which have been towered in an A/BOX 4000 or a Power Tower. 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 called the Mediator PCI 4000 which connects to both a Zorro III slot and a PCI slot effectively making them active.
Jumpers
Jumper | Open | Closed |
---|---|---|
Master | Use SharkPPC (unreleased) as the computer busmaster | Use Amiga's processor as the busmaster |
WinSize | PCI Memory Space is within a 256MB Zorro III boundary (Default) | PCI Memory Space is within a 512MB Zorro III boundary (needed for Voodoo 4 & 5) |
Swap Config | PCI I/O configured before PCI Memory (use with PCI graphics cards) | PCI Memory configured before PCI I/O (use with Zorro graphics cards) |
PCI Features
