The short version: What did a portable breathalyzer machine look like in 1982?
The long version: I am a huge fan of the British show Ashes to Ashes, a spinoff of the popular Life On Mars series. Season 2 of Ashes started this past Monday night. While the show typically does a pretty good job of showing early 80s technology, there was a scene that set my "television anachronism meter" off. MILD SPOILERS FOLLOW: In short, a police officer, on a hunch, reached into a car and grabbed a portable breathalyzer machine to test a suspect. The machine was around the size of a Tom Clancy paperback. Given that the walkie-talkies they use look like they're a foot long and three inches thick, I wondered if they had such portable breathalyzer machines in the UK in 1982.
Are there any police officers (or, well, drunks) that can clear this up?
Thanks!
