Mostly I was thinking of TMC (famous for the animation in Jurassic

CalTech maybe predating that, or competing with it, would be very
interesting. I'll look, thanks.
My only artifacts are DOS 3.2 and SVr4 manuals :-)

I was working off memory, and the iPSC/1 and iPSC/2 manuals I have
in my office as a historical artifact.
I seem to recall that if you google hypercube and intel, you'll
turn up some of the papers that were written early on. The guys
who started with the hypercube interconnect were at CalTech, as I
recall, and spun off to form a supercomputer company embodying
that, which Intel also adopted.
The problem with hypercubes is that the number of NICs per node grows
with the machine size. Want to double your machine size? Then add a
NIC to every node you already have. The number of nics, or links, or
cables, grows O(NlogN) for N nodes. You get a machine diameter which is
log N, which is nice, but there are ways to do that with a fixed number
of NICs per node such as fat trees or the Kautz/deBruijn family.
TMC had, among other luminaries, Richard Feynman to help work out the
routing software.
