Of course it's possible. :) I don't have a copy of 32V here, but in V7 on a PDP-11/70, the first RP06 disk pack appears to be exposed as /dev/rp0, and the second one as /dev/rp3. So, if you use SIMH to ATTACH a tar file to SIMH device rp1, you should be able to un-tar it with: # tar xvf /dev/rp3 or # tar xvf /dev/rrp3 The extra "r" here means "raw" device access, which is sometimes necessary. You'd need to create the tar file with all the ancient AT&T Unix compatibility options turned on. No GNU extensions allowed here! Perhaps more era-appropriate would be to use one of the tape devices, such as SIMH's TS or TQ devices, which may appear under UNIX/32V as /dev/tq*. If not, it might be something like /dev/rmt* or similar, meaning "raw-access magnetic tape."

UNIX/32V is contemporaneous with the 2BSD and 3BSD lines. So no, modern TCP/IP v4 hadn't been invented yet, much less made its way back home to AT&T. (TCP/IP was created in 1974, replacing the earlier NCP on the ARPANET, but good luck finding a modern stack that will talk to pre-v4 IP.) TCP/IP as we know it today didn't get into AT&T Unix until SVR3, accessible only via their ill-fated TLI API. AT&T Unix didn't get BSD sockets support until SVR4, the grand reunification of BSD & AT&T Unix.
