The things you find on ebay...

Well, some bits are obvious. It's a model bus (as in the passenger-carrying vehicle). 'Matchbox' was a common brand of such things in the UK, IIRC the name was used by 'Lesney Products' or some such. Such models were quite small scale, I would guess about 6cm-8cm long. OK, the pun on 'omnibus is also obvious. The 'bus' as in the passenger vehicle is short for 'omnibus' which as Michael Flanders said (at the start of 'A transport of delight' means 'To or fo, by with or from everybody'. And of course we all know the assciation between 'omnibus' and the PDP8/e. The only thing that puzzels me is where that advertiisng label came from. I don;t think it would ever have been a real advert on a full-sized bus. Back then people didn't buy computers ;-). My guess is that the label is not orignal. Either somebody has made it up appreciating the joke, or it was an advertising gimmick used to promote either the PDP8/e or a rival machien (as it 'This is what DEC's bus rally is' -tony
