Lego has just started to get into the gadget world, issuing a whole bunch of electronic items such as MP3 players and digital camera in the trademark Lego brick design. But this isn’t Lego’s first foray into electronics. Back in 1989 Lego and Tyco issued the Lego Phone. The Lego Phone was a working landline phone with ring and pulse tone switches. The fully functional desk phone had brick buttons and you could add one any Lego bricks you wanted to design your own phone style. Fun old school phone.
You can buy Lego Phone on eBay relatively cheap these days.
