After searching every available text/manual about SCSI(products) I still can't find an answer to a very simple question: What type of cable do I have to use to connect SCSI devices? In detail, does a (un)shielded 50wire flatcable do the job and up to which maximum length. Or do I need a shielded 50wire twisted cable. Any other possibilities? I _know_ there are ready made SCSI cables available but they are 1) much too expensive 2) here in the Netherlands nobody even ever heard about such a thing and I'm getting tired of explaining just what a SCSI cable is. I would much prefer the flatcable with press on connectors to be a viable solution but I'm not shure if it's all right. ANY HELP APPRECIATED!

Or do I need a shielded 50wire twisted cable. Flat cable, up to 2 or 3 meters long, is generally acceptable for SCSI. Of course, if you have an unusually noisy environment, or other EMI problems, shielding may be necessary. Don't you wish all peripheral manufacturers shipped cables with their equipment? -- ===================================================================== Ed Anson, Calcomp Display Products Division, Hudson NH 03051 (603) 885-8712, UUCP: [decvax, wanginst, savax]!elrond!anson (Just blame me; my boss isn't even certain about just what I do.)

In hopes of using the drives from this box, I'm having a six foot flat wire cable made up (D-style on one end, dual in-line on the other) and we'll see if it works daisy-chained to a HD20SC. In my experience, if the cable is terminated at all the right places, one could comfortably run 25 feet, but I'd stick to Apple's configuration limits to start out! Rob Lake
