Hello all!
I would like to find copies of excellent technical slides made by Philips years ago, about 1960 I think.
They where very good, and helped a lot the understanding of semiconductors and valves.
They where also very pleasant to see, showing the charges as little coulored spheres on black back. If you saw them probably you will remember of them.
The subject where:
- The crystal diode
- Principles of electron physics
- The tetrode and the pentode
- The cathode ray tube
I have a paper copy of some, they where published by an Italian magazine. Unfortunately I have not all of them.
And, more, I would like to use them to help a friend learning electronics, he is on the opposite part of the world, so I need them in electronic form.
Best of all, I would like to send him a link to a website where he can see them.
As the images are still very good today, and as they where made as educational support, I could not believe that Philips did not place them somewhere in their web site. But I searched, and was unable to find.
Now the question: did anybody see them in the web, or has he them in any form, or can he suggest me how to find? (I already tried to contact the Philips webmaster, but that link seems to be broken in the Philips site).
Thank you for any help!
