[TUHS] System III - TCP/IP

Hi, i have an old Z8001 based SysIII variant and I would love to have TCP/IP on it (SLIP first, later with a homebrew ethernet device). I wonder if someone ever saw TCP/IP available on a System III? I have lets say 90% of the kernel running on it as source available and I started digging in the available 4.2 BSD sources. It looks like there would be much to do to hack in TCP/IP on my own (no IPC, no Net, no PTY, no....). I got K5JB running (userland TCP/IP implementation) after I fixed some C code because the C Compiler available on the system is..... kinda limited. telnetd is of course not working as there are no pseudo-teletypes on this SYSIII. At least I got ping, echoping and ftpd up and running via SLIP (10.1.1.2 is my SysIII box:) # ping -c3 10.1.1.2 PING 10.1.1.2 (10.1.1.2): 56 data bytes 64 bytes from 10.1.1.2: icmp_seq=0 ttl=254 time=316.317 ms 64 bytes from 10.1.1.2: icmp_seq=1 ttl=254 time=297.328 ms 64 bytes from 10.1.1.2: icmp_seq=2 ttl=254 time=296.369 ms --- 10.1.1.2 ping statistics --- 3 packets transmitted, 3 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 296.369/303.338/316.317/9.186 ms # ftp 10.1.1.2 Connected to 10.1.1.2. 220 FTP version K5JB.k37 ready at Tue Apr 30 22:25:47 1991 Name (10.1.1.2:root): test 331 Enter PASS command Password: 230 Logged in ftp> get sa.timer local: sa.timer remote: sa.timer 500 Unknown command 500 Unknown command 200 Port command okay 150 Opening data connection for RETR sa.timer 2571 0.53 KB/s 226 File sent OK 2571 bytes received in 00:05 (0.48 KB/s) ftp> get wega local: wega remote: wega 200 Port command okay 150 Opening data connection for RETR wega 98723 0.51 KB/s 226 File sent OK 98723 bytes received in 03:05 (0.51 KB/s) ftp> exit 221 Goodbye! # So I wonder if someone got anything SYSIII -> Net/TCP/IP related which could help me in any way to get a SYSIII kernel capable of TCP/IP and PTYs to get a telnetd up and running via SLIP is my first goal.
