Rod! 8-). Can I be Rod? (Let's see, where is my curmudgeon hat...) Early C's were aggressive with bus timing and they ran into problems with substandard cabling. Adaptec modified them to slow down the REQ/ACK timing. If you had problems with those early ones, or if you bought a late early one, you will have resistors tacked to the boards. I don't think this has anything to do with internal versus external cabling - I think people are just more likely to have lower quality external cables sitting around. I know I did - I had some external cables that worked and some that didn't. I had the board "fixed". Peter -- *** March 13, 1996: Our ISP may be GONE.
