That was on a standard pump.
It is possible to remove the pump without removing the block and the engine from the car, phone me if you would like to know more on that.
This happened to me as well, back in the seventies, with my first Ruby. I was on my way to work at 07:15 when the oil pressure went to zero. I continued for another 4 miles with zero oil pressure and got into work on time!
A friend towed me back home, where I found that a big end split pin had broken up and a piece of it was jammed in the oil pump, seizing the pump solid and breaking the drive taper and key.
Since then, if I use split pins on the big ends (I prefer Nyloc nuts now) they only get used ONCE!
