PCB design related Links

[marce]

Having returned to work after a bit of time off to be ill, I returned to find Windows 7 newly installed on my machine.
So I thought I'd sort some of my desktop links etc, mainly related to PCB design, as that is what I do, here are the first batch that I have checked, to enshure they still work.
So the following are misc. PCB design related links which may be usefull.

Hello Marc,
Wealth of info, came across this thread by accident while searching layout related threads... Thanks for the post.

Also had never (I think) visited this part of the forum. mostly roiling the solid state, pass labs and chip amp forums. some links are dead now though.
regards
Prasi
