Here is an 8-port terminal server first sold by Digital Equipment Corporation in 1986. It was used by US Steel in Gary, IN through June 2015 when a tech noted that it was still working properly when he powered it off..
I can hear this DECserver MC/200 power on, can feel the fans, and see the green lights light up normally . Its single ethernet connection is DB15 AUI port.
