These two Monty Python-esque ad were made in the early eighties for the emerging British market for home computers. One of the themes of this series of ads was to position Compaq against IBM, the market leader at that time. I find these interesting because they seem to express the initial ambivalence that was common when personal computers were introduced. It seems to me that it has become politically incorrect to express this sort of resistance today.
This shows John Cleese comparing the new "Compaq 2 Desktop" with a dead fish.
This one describes what were then leading-edge features. As well as being funny, it struck me as an interesting historical snapshot.
