I don't know about ISC, but I have tested up to seven SCSI devices
(concurrently!) on SCO UNIX systems (4 disks + 3 tapes, & 3 disks + 4 tapes).

It's pretty awesome to watch all those SCSI access lights blinking across
seven devices!  You can't do much *else* with the system, once you fire up
all that I/O, but quite impressive, none the less.

FYI: For the curious, testing was performed on NCR PC's (microchannel) with
NCR SCSI host adapters running a port of SCO UNIX w/ NCR Common SCSI drivers.
Though we didn't test the same configuration on stock SCO UNIX with Adaptec
154x/164x SCSI host adapters, it should [theoretically] work, as well.  That's
what SCSI is all about!

Disk/Tape hardware was a combination of:  (all SCSI devices, of course)

	Disks: Seagate WREN IV 380 Mb (FH), Seagate WREN VI 380 Mb (HH),
	       Maxtor 8760S 760 Mb (FH), Seagate WREN VII 1.2 Gb (FH)
	Tapes: Archive Viper 150 Mb QIC (HH), Wangtek 525 Mb QIC (HH),
	       Exabyte 2.3 Gb 8mm (FH)
