[Simh] 4.2BSD with networking on a VAX 11/780

[Jason Stevens]

Glad you could reproduce it... although I did this years ago.. Finding the
driver in Google groups was a godsend, since it was pretty useless without
networking.

 

Years ago I built a few things for 4.2 to make it feel a little more modern,
although to be honest the UWSIC build of 4.3BSD is so much more useful.

 

I have tap files of the following binary packages:

 

gcc-1.21.binary.BSD-4.2.tap.bz2

dungeon-2.5.6.binary.BSD-4.2.tap.bz2

flex-2.5.4.binary.BSD-4.2.tap.bz2

gcc-1.42.binary.BSD-4.2.tap.bz2

bison-1.25.binary.BSD-4.2.tap.bz2

hack-1.0.3.binary.BSD-4.2.tap.bz2

gzip-1.2.4.binary.BSD-4.2.tap.bz2

gcc-1.27.binary.BSD-4.2.tap.bz2 

 

which are available here:

http://sourceforge.net/projects/bsd42/files/Package%20Tapes/4.2%20BSD/
<http://sourceforge.net/projects/bsd42/files/Package%20Tapes/4.2%20BSD/> 

 

And if you look around the project files, I have quite a bit built out for
more platforms as well.

 

I couldn't get an IRC client to build to save my life, but on 4.3 it was
pretty trivial.  I'd avoid RENO, it really is quite unstable when you push
it hard.

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
<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
<https://groups.google.com/forum/#!original/net.unix/qqCxhYWQPtI/c7Ptc1mjQ9s
J>  .  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
