Browsing the web, a saw this great picture of a famous CRAY 1A built in 1975 by Seymour Cray after four years of design work. It was revolutionary because it used ICs for the first time in a supercomputer even though they were around since the 1960's. Here is a picture of one in the computer museum.

What was interesting was someone decided to implement this machine on a FPGA. So in the matter of 40 years give or take a few, we have a quantum leap in technology
and an impressive reduction in cost.
The Hardware
The actual design was implemented in a Xilinx Spartan-3E 1600 development board.
This is basically the biggest FPGA you can buy that doesn’t cost thousands of dollars for a devkit.
The Cray occupies about 75% of the logic resources, and all of the block RAM.
