Yup, sellam's right, be warned however that your SCSI bus will be hobbled
to the speed of the slowest device usually.
And that common wisdom, performance-wise, is to use only 1/3 of your
available IDs for active devices. ie. on a wide bus, performance drops
like a rock with more than 5 devices on the chain. Not that this looks
like a high-speed rig to start with.
Actually, IIRC, a wide bus will be hobbled to SCSI-2, 20Mbit max, but
fater drives will usually run at 20Mb. SCSI-2 allows mixed negotiated
speeds. Put the slowest device at the highest ID.
