Can anyone give me a little advice? While I have two SCSI devices working like a charm in my machine, I'm still pretty ignorant about it, and I'm clueless about what to do next to expand my setup. I have an internal SCSI-2 controller (piggybacked on another vital card) which runs my NEC 3xi internal CD ROM drive. When I went to add a Seagate SCSI drive, I had to replace the cable for with 2 device `sockets'/connectors. Later, I was told that I need not have replaced the entire cable–that I could have `popped' on a new 50-pin connector along the length of the existing cable. Now, I desparately need to add an external SCSI device–soon. Like, by Saturday if possible. But I don't know how to run this cable to the outside world and to a scanner. While SCSI devices seem to have 50 pin plugs, I'm told that this is reduced to a DB25 connector on the PC's backplane (that 26 of the 50 pins are ground lines and are tied together), and then expanded again with a special cable. This would be good, since my tower case has punchouts for DB25s and little else, but… * Why can't I find parts–or preferably kits–for doing this in any catlogs? * Is it true that I can somehow branch off my existing cable, rather than replace it? * What about these terminators? The external scanner would have one, I understand, but isn't my CD-ROM drive also internally terminated? Will there be a conflict there? I would greatly appreciate some advice and direction! Even if I knew what to buy, it's hard to find these esoteric parts listed in Computer Shopper; small parts would seem an ideal thing for Compuserve's PC Catalog to deal with, but it doesn't. I need this external port badly, but have no free card slots to spare for another SCSI card, so I must make this situation work! Thanks very much in advance to anyone who can advise me. —KAT
