software via radio

Was it this list where people were recently talking about receiving software via the radio? Apparently the UK service was called Basicode - I'm just slogging my way through a pile of documentation donated to the museum to sort out the useful stuff and stumbled across an apology letter from the BBC. Seems they'd moved transmission from Radio 1 VHF to Radio 1 MW and they didn't exactly tell people in advance :-) The letter's dated 18th October 1984. Seems that the data was transmitted as part of a radio programme called 'chip shop'. Now, I'm certain I remember seeing a manual about Basicode; I just left it in the pile at the museum that I'm yet to look through as it had 'basic' in the title and so didn't look immediately interesting :-) It was with a Dragon 32 machine (which also came with a lot of software), but whether any special hardware was needed I don't know.
