what's the world's biggest circuit/motherboard?

[John Boffemmyer IV]

         Also, the circuit main boards for scanning electron 
microscopes used to be boards over 2ft in width and length. I know 
now, that many of those same boards are scaled down to much smaller 
sizes to be rack mounted next to other scientific gear in labs.
         My brother received one that was determined to be defective 
beyond repair from his professor when he was at college for 
microprocessor design and engineering at R.I.T. in Rochester, NY. He 
unfortunately lost it in his move to Buffalo, NY after he lost 
interest in microchips (I know, sacrilege) and took up Linguistics at 
SUNY Binghamton, NY and now on to Buffalo University, NY. I think he 
still has some various odds and ends, but nothing significant because 
of storage (or lack thereof).
