On this link you will see three pictures of the MicroA1 "Industrial" motherboard: http://lain.ziaspace.com/~ryu/a1. On the pictures you can see that it still uses the ArticiaS northbridge, as well as the VIA 686B southbridge, but a standalone Sil0680 IDE controller is there as well.

They did it. This is what we just know from the comment #16 (from Adam Kowalczyk).
According to him a PLD was added to allow *6* bus masters on BUS-0.
To BUS-0 six bus masters are connected:
1. Southbridge VIA 82VT686B,
2. one PCI slot (for ONE PCI card only),
3. ATA-133 controller (Sil O680),
4. FireWire (VT6307),
5. Sound (CMI7838) and
6. one PCI-104 slot.
The 7th bus master included on the uA1-I board (RTL8110 NIC controller)
had to be connected to BUS-1 together with the ATI Radeon 7000 chip.
This downgrades ATI Radeon 7000 capabilities from AGP x2 to AGP x0 (= PCI).
It means Radeon on the uA1-I board can work in PCI mode only.
But why they did it? No need for AGP in Amiga?
> Perhaps Radeon7000 does not gain anything from AGP2x ?
Maybe you should send your comment to ATI? ;-)
