Most of us who grew up in the UK in the 60s and 70s have remarkably similar memories of the telephone in our family homes – and with good reason.

For more than 20 years, from the end of the 50s to the early 80s, the vast majority of GPO customers were issued with variations of the same phone.

These rotary dial phones – part of the 700-series – were available in different colours, such as red, mustard and two-tone green, but many customers opted for cream to blend in with home furnishings or, in offices, plain old grey.

It wasn’t possible to actually buy a phone – it was provided as part of your line rental. And, until the introduction of plug and sockets in 1981, you couldn’t swap around devices as your phone was hardwired into the wall.

Using a rotary dial seemed perfectly natural at the time, but once push-button phones arrived in the UK in the 1980s, there was no going back.

So what, we wondered, would youngsters from the digital generation – more used to mobiles than landline phones - make of a rotary dial telephone?

You can see for yourself in the video above, the latest in our series in which we test popular gadgets from 80s Britain on a group of five to 12-year-olds.

Amazing, but true: none of these kids had ever literally ‘dialled’ a number before…
