[Test-Equipment] Mega-node Sr.?

[Mike Sloane]

Thanks to all for the helpful information. If anyone wants it, let me 
know when they want to pick it up in Allamuchy NJ (I am not even going 
to think about packing and shipping it). If nobody wants it, it will 
likely become a chassis for a project and a parts mine.
