Dave,
Well, Mike Schiller confirmed what you said about the scsi connections.
I really didn't think that you could actually chain across system busses. Now,
my interest is piqued. My tower has room for my spare VGA card and my ST02
SCSI controller for the PC. If I remove the multi-i/o card I can run a scsi
hard drive on the PC side and chain to the Amiga side and have access to my
tape drive for backup on the PC side. Unfortunately, my cheapo PC scsi won't
live with the IDE controller and it is very simple and cannot be flexibly
configured. The controller is "hard wired" at ID7. I don't even know if the
card is in any way terminated. It has no terminators on it and I never used it
but with one terminated drive when it was connected to the bridgeboard.
However, the card will handle up to seven devices, although I think the devices
must have their IDs in numeric sequence or it won't recognize a device.
Can I just daisy chain this sucker anywhere on the Amiga scsi chain,
renumber the Amiga controller to ID6, and it would, presumably, "see" the Amiga
devices already on the chain? The controller also has no drivers or software.
I don't even know if it will work with a scsi tape drive through Fastback
unless there is a driver. Does this mean I really need a "better" controller,
perhaps with the Corel suite of drivers? If I really need a better scsi
controller for the PC side, which would be the best device to look at? Of
possible concern would be one that is known to work with OS/2 2.1 (I have it,
but don't know if I ever want to use it.)
