UNIX SYSVr2 Source Code r2

This is AT&T's UNIX SYSV r2 source code. The base target here is the VAX. R2 includes lots of BSD addons, but TCP/IP was not one of them. For some reason in their infinite wisdom AT&T wasn't big on TCP/IP, probably because it was too open. Hackers from all over the world wanted this very file, there was even espionage from the Soviet Union to steal this. So here we are. Enjoy Comrades!

UNIX SYSVr3 Source Code r3

This is AT&T's UNIX SYSV r2 source code. The base target here is the AT&T made 3B2. Which I might add was the UNIX machine that ran the phone system. If you were into phreaking and hacking you faced this UNIX everywhere. So here is the source code. Maybe one day there will be a 3B2 emulator?
