Re: Prestel and Micronet 800 dialup - how did it work?
It's surprising how challenging even a 1200/75 baud connection was at this time.
Granada TV trialled what was probably the first example of electronic audience participation.
The programme eventually became " The Granada 100" and there were (notionally) 100 audience members with terminals set up so they could vote on the big story of the day.
My involvement was supplying the equipment, two Labgear Viewdata terminals. They needed to communicate directly with the audience research people AGB/BARB at their
Hanger Lane, London headquarters. The programme went out at about 6pm and the idea was at the end the viewdata box would show the voting result graphic.
The first few programmes did not go too well with lot's of random gibberish on both the primary and backup terminal.
Someone had the idea to dial the boxes in at lunchtime, and provided the connection was clean, just keep them on-line until showtime.
