It was the AT&T pixel-machine, a massively parallel graphics system.
SGI hardware relies primarily on pipelining. They have a custom floating
point ASIC which they download configuration code into at boot time.
They have strung a bunch of these together (4 of them actually) and
each performs a separate rendering task. I'd elaborate on the two machines
but I'm in a bit of a rush at the moment. Drop me email if you are
interested.
