Yeah, but OP found a T-R pic as second response. I was thinking the old firehose ethernet with bayonets and vampire taps until I saw the pic. That stuff was bigger than RG-8U coax IIRC. There was a big orange cable drop into one of the adjoining offices from the big iron back in 1989.Originally posted by: Markfw900
It could have been thick ethernet, about 15-25 pins, and about the size of a joystick port ?
