In the Netherlands they used to broadcast software as part of the Hobbyscoop radio show. It was generic BASIC code that could run on a variety of home computers, requiring a small loader program for conversion. The project was named BASICODE[1].

Simply Amazing. I'd love to know more about this.

I still have some old Amiga backups on VHS. Worked too… :)

In Poland, in the communist period, the national broadcaster used to do it. For Atari, ZX Spectrum, Commmodore 64.

Haven't heard the audition, though. Well before my era.
