Happy new year!

I thought I’d go ahead and see if I could get Net/2 to build on my own.

Net/2

Net/2

Well it compiles, and tries to boot….   Sadly there is no adb or gdb support.  How on earth did people debug this stuff then?  I’m not sure where the crash location is, or what to do about it.  But I thought this was really cool.

I’ve also tried to track down 4.4BSD encumbered, which was released around the same time as the 4.4BSD-Lite1 which was after the AT&T vs BSDi/CSRG thing..  Or even the release that parallels the Net/2 release…

Anyways, happy 2014!

Some minor work on SIMH

So it’d been a while since I’ve booted it up, and I just went with the 3.8-2 rc2 release (I forget did that version ever get released..?) Anyways since I wanted to run my SIMH instance under a Linux VM..

Soooo I went through some fun to recompile it as a 32bit binary, as the slirp doesn’t work on 64bit machines..

I just built the 11/780 emulator as I wanted to run 4.3 UWisc on my VM (in a VM)..

You can download the build here.

As a reminder the installation instructions for 4.3 BSD Uwisc can be found on gunkies, and all the files needed are on sourceforge.  Also the 4.x BSD if_de.c driver errors out on receiving packets, and I’ve found it easier to just remove the error checking from the driver, and recompile the kernel and just boot that up.

I’m thinking of rebuilding the login process on 4.3 BSD to bring back AberMud, and self service user creation.  Years ago I used to host all kinds of ancient UNIX, and I’d like to bring back at least one..

4.1c BSD

It’s been a long while since I’ve posted anything VAX BSD related.  So I found this ISO image a while back that had all these old versions of BSD on them, but sadly many of them are incomplete, missing parts, and give really no clue on how to use them.  There is even some duplication thrown in there just to complicate things further.  So I figured I’d try one of them, an interim release of 4 BSD and see if I could just overlay a newer release version and see what I get…

Pretty cool.  And oddly enough googling around doesn’t seem to find much about people running 4.1c BSD, but it is significant with the first version of sendmail being bundled, and rogue.

The release also includes TCP/IP support but I haven’t the slightest idea how to use it.  I suppose reading the instructions is key.  But I thought I’d share this little fossil first.

For those who want to try it, you can download it here.  It’s using SIMH, so if you aren’t running Windows, bring your own VAX 11/780 and you’ll be good to go.
