The vector feature was available on some models of the 3090. It was a SIMD (Single Instruction applied to Multiple Data operands) vector engine and IIRC you could add VF engines but each one had to replace a general purpose engine. IBM offered them because customers wanted them. The financial community bought a number of them and for a while in the mid/late 80's the 3090/600s were in the top ten or so of super computers. I guess it just didn't intrude on your world Ed.
