Adage Ambilog-200 and AGT-10/30/50 were vector computers with true vector
displays. In fact the AGT-30 and 50 supported a hardware 4x3 multiplier
(implemented with 15 bit multiplying DACs) and did 3-D vectors with depth
cueing. Very unique 30 bit 1's complement machine which was RISC-ish in
design.
Sadly not much info on them survives on the web. They were the first
machines that I ever played Spacewar, Life, Lunar lander, etc. Also the
only machine I ever used that had foot pedals.
