I was at Atari when, one fine day, some folks in the UK that we had never heard of did a product announcement about an Atari computer that definitely was not coming out of our engineering group. (We were down to one building at that point, if you don't count our remote office in Monterey as part of the GEM porting effort).
I remember the Tramiels being a little flabbergasted by the Transputer announcement as well.
