There was a Three Rivers Graphic Wonder (a vector display) on the
University of Toronto PDP-11/45 in 1975, maybe 1974. There wasn't a frame
buffer until Dave Tennenhouse built one around 1978 - not sure of that
date, maybe a little later
.
256x256, 8 bits per pixel, or 65kilobytes, the full data address space of
the PDP-11.
