I remember doing it to impress my friends at how easy it was to beat the computer with my first chess computer, in the early 80's! Anyway, it was quite dumb : weak at tactics (it would miss mates in 2!!!), strategy, endings and once out of book and after, say, having played g7-g7, it would throw its bishop on c5 or b4 and castle! I was starting to play, then, and was very weak (I still have several of the games I played against it!), but even if I was a piece or 2 down, I could still draw or even win! Not too good to learn, since your mistakes are never punished!
