> TCP/IP, not datakit.
The V8 manual contains internet(3), tcp(3), and udp(3). In the copy I have these are dated 8/7/85. Down in the kernel in /usr/sys/inet the earliest files appear to be dated 3/22/85. I'm going to do a comparison with the 4.1cBSD TCP/IP stuff because a casual glance reveals some overlap.
