When using Ultra SCSI single-ended devices, you can connect 

up to 8 devices if the total cable length is no longer than 1.5 

meters (about 4.5 feet). If total cable length is between 1.5 

meters and 3.0 meters (about 9 feet), you can connect only 

4 SCSI devices. Error-free operation is not guaranteed if 

you exceed these limits.

When not using Ultra SCSI devices, SCSI specification limits 

total bus cable length for single-ended SCSI to 6 meters or
