The LINC, LINC-8, PDP-1 and PDP-12 all had vector

None of those were vector displays. They were point-plot. If you wanted
to display a vector, you had to display a suitable number of appropriately
positioned points. The Type 30 display system for the PDP-1 was optional,
and there was a variant of it that could display characters.
The 338/339/340 display subsystems (for the PDP-8, PDP-9, and
PDP-1/4/6/7/10 respectively) were vector displays.
