Nobody actually uses System V anymore, but because it's the thing other Unixy systems are based on, people keep extending the SysV ABI standard to processors ridiculously more powerful than System V itself could ever hope to run on.
As best I can make out, the only relevant portions of the original SysV ABI document are chapters 4 and 5, still available and maintained on the SCO website:
http://www.sco.com/developers/gabi/ http://www.sco.com/developers/gabi/
There are also separate documents defining the details of the SysV ABI for each processor family. This StackOverflow answer links to some:

... and the OSDev Wiki links to many more:
