Hi Clark,
Thanks for your reply.
My other PCI cards are Creamware/Sonic Core Scope DSP cards (3x) and one
AGP video card. The Scope cards can run under OSX, but I'm mainly
working with 9 due to the OASYS PCI. I'm also more familiar with OS 9
than X.
As for slow transfer rates with USB 1, I could possibly live with that.
In most cases, it would be fairly small transfers.
My main concern is reliability and functionality. This area is pretty
new to me. I used to use Amiga for music back in the day, but often
heard about other users with pro samplers connected via SCSI to their
Macs (I think G3 mainly). There is host control software to run under
Mac OS 9 for this. I have the samplers now (they are cheap at this
point) and really like the sounds I can coax from them, but would like
to integrate them into my computing environment. I don't really know
what I'm doing though.
I have read a little about Magma PCI expansion chassis which are
supported under OS 9. Never used one though. Would an Atto SCSI card +
PCI chassis be a reasonable solution? Does adding an expansion chassis
cause any issues with the PCI bus performance? As I'm running a lot of
live DSP audio processing, which uses main memory to some extent, as
well as some CPU load (I think not a lot though) I would not want to
cause issues in the bus performance.
Thanks again for your help,
Oli

I have a G4 MDD (FW 400, not 800 model), which I would like to add SCSI to. All
my PCI slots are taken up. I am mainly using this with OS 9.2.2. I would like
to know what is the best featured/most reliable option for adding SCSI for this
machine, that doesn't use a PCI slot?
I use the machine as a legacy DSP farm for my home music studio. I use a Korg
OASYS PCI card, which will not run under OSX. My idea for the SCSI was to
interface with my old hardware samplers (EMU/Ensoniq/Akai).
I have read about some Firewire and USB SCSI adapters, but information is a
little sparse as to how these really perform in practice. Some also don't allow
a complete SCSI chain, just one device. If really necessary, I could possibly
try to free one PCI slot, but I would really rather not. It seems that some PCI
SCSI solutions were more highly regarded. I certainly would not want too much
hassle with an unreliable solution, if that's all I would get with USB/Firewire
SCSI adapters.
BTW, I have heard of PCI expansion racks to add more PCI slots; are these any
good? Is there a performance degradation with these?
Well, forget USB, OS 9 only supports USB 1.1 so you'd be limited to 12MBps.
Most of what I know about the Firewire - SCSI adapters is that they are rare.
What other PCI cards do you have, maybe there are some options there.
