That is also very close to SVR4. I don't have the details at hand, but perhaps someone on this list does. Is there a reason you need to see the source code specifically for SVR4?

Sadly, System V as a whole is still regarded as a commercial product and no source is available. If you want the source code for a decent early-90s Unix implementation, I'd take a look at 4.4BSD. It's not SVR4, but it's from the same era and has many of the same abilities.
