No, it's actually a board edge connector, like the SA connector for a floppy drive, only a lot bigger. I thought the same and I spent time tracing both the controller card and the drive: the one thing I try to look for first are the termination resistor packs - can't see any. Ooop. I am begining to wonder if this is really worth the effort. The skip looms.....
