In the early to mid 1980s I used Tektronix storage terminals hooked up to a PDP-11 and/or VAX. And we also had an AED terminal that did raster graphics. All via serial comms.

There's a bunch of AED documentation online, including this...

(searching for AED graphics terminal will lead you to the user manual which has a lot more detail and electrical specs and so on)
