A couple of weeks ago, soemone mentioned that one of the companies that sells hard disks were selling 25 pin SCSI terminators. Now that my roomate need a 25 pin terminator, the article has expired. Could someone please send the name of the company that is selling the terminators?

Sure enough, there were the 25 pin terminators. Comments follow: 1. I have the IMPRESSION that these are "end of the line" terminators. ie. you can't put one between your mac and your first drive (directly). They look like a RS-232 loopback plug, ie a RS-232 cable end plug without the cable. 2. They were somewhere between $35 and $55 (I can't remember which since I loaned the book to a friend). All I remember is that It was too expnsive for my budget so I will not be getting any. 3. The terminator in a RS-232 plug gave me an idea. I'm going to make my own. All you need is a DB-25 type connector and sheild and (I think) two SIP resistors of the correct value. Using some small lengths of wire, solder the SIPS to the connector, wrap in electric tape (hacky but effective), and screw on the shield. Since we are allowed to have small components from work for free, this seems like a feasable approach. Any other ideas? -- Jeff Wiseman: ....uunet!tellab5!wiseman OR wiseman@TELLABS.COM
