TP was indeed amazing, though I think you&#x27;re misremembering — TP 5.5 was the first version to add OO extensions.<p>It came with a separate little manual just for the object-oriented stuff (beautifully typeset with the same type of syntax flow diagrams that Apple did [1]; Borland&#x27;s OO extensions came from Apple Pascal, after all), and I remember reading it from cover while on vacation when I was in my mid-teens, and having my mind blown by the ideas of object-orientation, which seemed like complete science fiction at the time.<p>Anything from your recollections you can add to this? Was there any collaboration with Apple at all?<p>[1] <a href="http:&#x2F;&#x2F;pascal-central.com&#x2F;images&#x2F;pascalposter.jpg" rel="nofollow">http:&#x2F;&#x2F;pascal-central.com&#x2F;images&#x2F;pascalposter.jpg</a>
