Back in those days, you were far more restricted by the following two things:
1) Rules about foot placement

Laver's serve was the quintessential evolution towards a pinpoint serve heavily engaging an extreme SSC, extreme racquet drop, and strong kinetic chain.
He looks like he's trying to copy Rafa's takeback.
