I've posted stills from 4mationsidents before, here and here; these ones were again provided by students. I don't know exactly when they were made, but they were presumably introduced around 1996, when the channel first adopted its "four-circle" logo.
Some stills from three films by Ian Emes. First, his beautifully crafted 1977 video for Linda McCartney's Oriental Nightfish, which can be seen here.
Next, Emes' first animated film: French Windows from 1972. Watch it online here.
And finally, an eighties advert for New York Seltzer soft drinks ("they're from the city, kitty!"). The ad can be seen here; Emes describes it as saving him from bankruptcy following his 1986 live action feature Knights & Emeralds.
