I wasn't involved when any of the projects were started, but it's my
understanding that NetBSD was first. Certainly, it was the first with a
release.  So, I would say, "don't ask us, when we started there were none."

Now, if you think about it, there are really four BSD's. The for-profit BSDI
did a release even earlier than NetBSD.
