Indeed...PCI was getting going good in the mid 90's (Wikipedia says it was created in June of 1992), and the LC dates to around 90-91 I think? I was going with the assumption that both ends must be terminated, and if there's no selection for on-board termination, then it must be automatic. I didn't realize that if the bus was short enough that you could get away with only terminating one end. I recall terminating resistors on old ISA SCSI cards, but don't remember seeing any on PCI cards...guessing the automatic termination must have started somewhere in that era...but as you say, probably after the LC.
