Where do I find the Corum's notes and all the things you mentioned.
I'm in desparate need for some url's. Would you be so kind to tell me some.
A search engine give's the most riduculus mess when you search on these
keywords.
My link with the Pupman site god cut of somehow and Gozilla imediatly
responded
with showing me a large list of Tesla.zip files on mirror sites who probebly
don't had
anything to do at all with my interrupted download (saved the list though
(might be interesting to look at some rainy afternoon)).
