Probably not , but I just spotted one whilst watching Alien Files Reopened! It was in Episode 6 of Series 1 (on BLAZE), very roughly 17 minutes in, then again briefly around 38 minutes. Maybe not quite as exciting to some as spotting a little green man but it was the highlight for me anyway!
I have very hazy memories of seeing the same thing (well an A2000, may have been in a history of computer games documentary). I spotted an A1200 a few years ago, in some low budget disaster movie but I'd never remember what that was called. I was glad I took note this time.
