x-ray, woof, I feel like a pre-schooler wandering in a college classroom. Okay, what's a d-sub cutting in the case? I have to assume you're talking about the 4 openings behind the board that are plugged at the moment, right? I'm still confused somewhat (read thick headed). It looks just like a socket with 50 pins....How does it terminate? I have this old Intergraph workstation which I took apart and it has a cable from the HD with a clunky chrome box about 1/2" by 1/2" in cross section plugged into the end of the cable and I thought that was what a scsi terminator looked like. Let's face it, I'm a sculptor who specializes in wood fired ceramics. My knowlege of the inner workings of computers is much the same as my knowlege of cars: I can change the oil and spark plugs. With computers I can install cards and drives. What makes them work is a mystery to me. Anyway, thanks for the info! If you ever want to know how to build and fire a noborigama kiln, don't hesitate to ask. 8-)
