Hi all, As part of ongoing efforts with a different project I set up a 4.2BSD install on a vax780 sim with networking support. After I did it I realized that I wasn't sure it had ever been done on SIMH before, so I wanted to let folks know that it's possible. All I've tested so far is the ftp client, but I was able to download files from a machine on the local subnet as well as a machine on the larger internet.
If you want to try it out, http://occs.cs.oberlin.edu/~hbent/vaxultrix/42bsd-net.tar.bz2 is a virgin install of 4.2BSD on an RA81 complete with an ini and bootloader file, ready to go. I just added the DEUNA driver and recompiled the kernel based on my local setup. It was tested with the most recent version of the vax780 simulator from git, I have no idea if it will work on any other version. Adding the driver was actually fairly easy. I found the original 4.2BSD driver on google groups: https://groups.google.com/forum/#!original/net.unix/qqCxhYWQPtI/c7Ptc1mjQ9sJ . This is the direct ancestor of the driver from 4.3BSD as well as Ultrix. It did not need any changes to compile, just an update to /usr/sys/conf/files.vax and an addition to the kernel config file. Enjoy! -Henry
