I have a few Commodore 64s, from the middle-early 80s. Then there's the TI-30 calculator and the Atari 2600, both from the mid 70s. If you want to count it as such, my house was built in 1952 and has a cute little switchboard to break out a phone line to every room (and I mean every room, there's at least 6 lines in my two bedroom house). It even has cute little handwritten paper tags attached to each line.
