BSD/OS

386/BSD was a commerical BSD OS that was released by BSDi.

At the time it was noted for shipping on a CD, and having its full source code available for purchase.

Despite this, it was caught up in the AT&T vs CSRG lawsuit, and while its future looked uncertain, the world had shifted to the Linux kernel which had no legacy or ties to AT&T.

I think there were only a few releases before the company folded.
