Which tech sound instantly transports you back in time?

That unmistakable series of beeps, static and warbles that meant you were finally connecting to the World Wide Web. Just don't pick up the landline, Mum!

That jaunty little tune had every teacher in Britain confiscating phones in the early 2000s. Bonus points if you were also mid-Snake high score.

Bill Gates' gentle chime that signalled the beginning of a school ICT lesson or an evening on MSN Messenger. Instantly comforting.

That satisfying clunky button press while flicking through 200 channels to find nothing on. A true British living room symphony.

That eerie, dramatic hum as the grey box booted up meant Crash Bandicoot or Tekken 3 was imminent. Peak childhood.
