Just asking for trouble. Even if you terminate the last device on the internal 4' length. > <--------- 4.5 feet ---------> > C--------+--+--+--+--+--+--+-T > \ / \ / > 6 inches 3 inches > > + == device connector. > C == external connector. > T == terminator. Ideally your internal cable should have two external connectors, one at each end. And whatever internal stuff in between. But if you are dealing with a box with 7 narrow SCSI devices there is no point in having a 2nd external connector and the later above cable is perfectly correct. A pair of scissors could trim off one of the 20" legs, then put a terminated drive on the end of the 4' length and you'll be OK. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
