And indeed with the speed of modern machines with clock speeds in the GHz
and TFLOPS, and thousands of cores in some devices, we use large SI
multipliers so

That appears to be an earlier model of a similar system we had at UBC
which could crunch arrays of FP numbers at 10 Mflops. Had it
connected to an 11/44 and just recall doing some frantic programming
mainly involving using minimal code as had to use memory management
to allocate memory pages
I recall the FPS AP120B as an add on for PDP11 boxes, 11/45, 11/70 for
some serious signal processing apps.

Those are the best reasons!!!1

I picked this up a number of years ago for reasons that entirely escape
me. It's certainly neat, but I don't see myself ever actually using it and
it's large and heavy.
