The journey is documented here:

The network code is in a different tree, I'll move it over to the above tree over
the weekend.
Posted the network bit in the online repo; it's in the v6net directory.
Also fixed the instability - it is quite satisfying to login to v6 from a 'nc'
client on modern hardware.
However, I also found that the BBN code from November 1981 is what is says on the can:
beta.
I'll move to the October 1982 code when I find some time.

PS, this is the 'server' that nc connects to:
#define unchar unsigned char
#define netaddr unsigned long
#include "con.h"
#include <stdio.h>
#include <string.h>
unsigned long
ipaddr(w,x,y,z)
int w,x,y,z;
{
unsigned long ip;
ip = w;
ip = (ip<<8)|x;
ip = (ip<<8)|y;
ip = (ip<<8)|z;
return ip;
}
struct con con;
void
child(fd)
int fd;
{
close(0);
dup(fd);
close(1);
dup(fd);
close(2);
dup(fd);
close(fd);
execl("/bin/sh", "[net-sh]", 0);
}
main()
{
int i, n, sd;
con.c_mode = CONTCP;
con.c_fcon = ipaddr(192,168,1,114);
con.c_lcon = ipaddr(172,16,0,2);
con.c_fport = 0;
con.c_lport = 4000;
sd = open("/net", &con);
printf("Connected\n", sd);
child(sd);
close(sd);
}
