It's easy to forget just how awful mobile phones used to be - but one look at the Motorola 4500X serves as a reminder that mobile phones were once something that you really didn't want to carry around unless you had to.
Dating from the late 1980s (we believe that our model is a Vodafone UK device from 1988), the 4500X was a massive 3.5kg device which was basically a handset connected to a heavy box containing the battery and electronics via a curly cord. The unit measures 260mm long by 118mm wide by 175mm tall (270mm if you count the antenna). This type of phone was known as a "hand portable" and it was just one step up from a car phone.
The handset itself had a basic set of numeric buttons and some function keys, with a very simple LED display for output. There are no letters on the keys, because text messaging was still to come
