Multiple IDE devices on single Acard 7720UW

[danbeaver]

IDE "Controllers" can have 2 devices, a Master and a Slave; the ACard is a "Bridge" or a conversion device, not a controller.

Well the controller is the SCSI, so there could be 7 SCSI I/II or 15 SCSI III drives off the bus that were bridged to the SCSI controller; a tad bit expensive for my taste and each ACard Bridge requires a wee bit of time to do the conversion, but it is possible.

Edit: Does the Amiga even recognize when there's an ACard plugged in?  I would think it would be invisible to the system, the Amiga would just see the device at the end of the chain?

Well if the ACard is "plugged in" the end of the chain using a good lubricant, it might not notice until the device got off; however I just don't see how the Amiga wouldn't notice this initially.
