Or you could buy an Excelan unibus ethernet card and their
Exos front-end TCP/IP implementation.  It adds about 8K to your kernel
and has the 4.1c network system call semantics, but it offers
the standard suite of network utilities (rcp, rsh, telnet, etc).
I have done that here on some PDP11/45's (not enough core to handle
2.9's network code) and it works fine.  Good throughput too (~60Kby/sec).
It takes about a man-week to make the mods necessary to get the drivers
to work on 2.8bsd.  I have the 2.9 stuff if you're interested.
