There's a copy of ultrix-11, which is v7 based with some 4.1BSD additions,
including sockets and a TCP/IP stack. Don't know if it runs on the smaller
PDP-11, but it looks like it might. The sources are in the TUHS archives.
Seems like the best low-end v7ish kernel with TCP/IP around, but I've not
used it extensively.
