@ Fred_M - Chips die je niet kunt eten....
The recordings took place at the AMC of Amsterdam, top floor. There was a professional recording studio. I was one of the guests showing his creation. Their programs were subsequently aired on radio, and afterwards, these recordings could be loaded by the Atari recorder aka cassette drive.
Aired by Vara....
Unfortunately there are no recordings left of these episodes on the internet. Well... somewhere I still do have a copy left on Philips 2000 format, which i won't release
Nice topic, though !
