I don’t know why I just remembered this, but…
When I was a kid I recall reading that during or shortly after the Falklands war there was a “game” played on teletext where one attempted to sink the Belgrano. I remember a screenshot, which appeared to show graphics far in advance of what I had ever seen in teletext, and I wondered in the article author had become confused.
It was in a major magazine or newspaper, can’t recall which. I also seem to recall color, which would imply a magazine.
Is this ringing any bells for anyone?
