There was quite a bit actually. The LINC, LINC-8,
PDP-1 and
PDP-12 all had vector displays. There was also an add-on for the
original PDP-8 and PDP-6, display 340 or something like that.
No, they were point displays, no capability to draw a vector.
The LINC, LINC-8 and PDP-12 at least had character generators
that would draw a 2 x 6 grid of dots from a 12-bit word. Two
of those grids would draw a 4x6 dot matrix character on the
screen. So, a character could be drawn with a small number
of instructions.
