I've got a Dell P2-400 that I got from my current employer 3 years ago, it was probably 1 to 2 years old at the time. Its got a SCSI drive in, 8GB I believe, running off an Adaptec controller. Its at home now so I don't know if its 68-pin or 80-pin, my guess is 68 as the cable is fairly small, and I think it was some form of SCSI-2. A friend is hooking me up with a current Seagate drive. Can anybody tell me whether or not SCSI is backwards compatible? Or will I need a new controller? I know, I'm not providing much information, but I'm just curious how much the SCSI spec has changed over the past few years.
