Re: broadcast the code
Yes.
Also there were floppy cover discs on magazines. A 7" floppy to play on the record player via the cassette interface.
Back in the 1930s home 78 rpm disc recorders did exist. The 22 line TV and also fax was broadcast on UK and USA Medium Wave (Broadcast Band) transmitters after close down, which wasn't that late at night. Baird's wasn't the only mechanical TV and was obsolete even then. Some home recorded on 78s with 22 line TV survive.
Also even cover disc 78s existed, pressed shellac or plastic on one side of a thin card base.
So loading programs from record player discs and transmissions predates the launch of the IBM PC in the UK. The Act Sirius 1, aka Victor 9000 was actually released in the UK before the IBM PC and was seriously better.
Actually wasn't the floppy originally for loading microcode if the Mainframe was turned off and Gary Kiddal founded Digital Research because no big company was interested. The original DOS being a rip off, sorry re-imagining, of his 8086 version of CP/M by a small company bought by Microsoft.
