32v is the first 32bit version of Unix created by Bell Labs. 32v is basically a 32bit version of [[Seventh Edition Unix]] ported to the [[VAX]]. While not the first 32bit version of unix ([[Interdata]]'s was), it was the most influencial. 32v could only run on the [[VAX-11/780]] as it was the only VAX in existance at that time.

It's also worth noting that [[CSRG]] used 32v as the basis for their work on 32 bit BSD unix, starting with [[BSD 3.0]] which was a 32v kernel with demand paged virtual memory, the BSD 2.x utilities rolled into one. Neither 32v nor BSD 3.0 include [[TCP/IP]].

== The AT&T vs BSDi/CSRG Lawsuit ==

Because 32v is the basis for BSD 3.0 it was also the source of contention of the lawsuit. The whole issue has been made moot since Caldera bought the rights to UNIX, and released 32v as free software.

== How do I get this to run?! ==

Right now, make sure you have the [[VAX-11/780]] emulator from [[SIMH]] 3.8-0 or higher, then go to [http://zazie.tom-yam.or.jp/starunix/ http://zazie.tom-yam.or.jp/starunix/] for more information.

== What Runs? ==

Not very much.... 32v does not provide any modern networking, and the C compiler is far from ANSI.

This was the last research version to leave Bell Labs. This also proved to be quite a portable version.

== Platforms ==

These are the known platforms to run Unix v7

=== PDP-11 ===
the [[PDP-11]] was the primary platform which Unix v7 was written on. All other v7's can trace themselves back to this version.

=== Interdata 8/32 ===
The [[Interdata 8/32]] was the first port to a 32 bit platform outside of Bell Labs.

=== Sun 1 ===
The [[Sun 1]] workstations ran a port of Unix v7 that was done by [[UniSoft]]. This was prior to Bill Joy joining [[SUN]] bringing [[4.2 BSD]] with him.

=== IBM PC ===
The [[IBM PC]] port was done by [[Microsoft]] however they resold it to various other OEM's under the name [[Xenix]]. Eventually [[SCO]] bought the rights & the Microsoft division responsable for Xenix, along with a deal giving Microsoft a portion of all SCO sales.

A separate project aims to port V7 to the 80386 native, [http://www.nordier.com/v7x86/index.html V7/x86].

=== Digital VAX ===
The [[VAX]] port was to the [[VAX-11/780]] platform in the form of [[32v]]. This port was the 'official' port by AT&T to the platform.

== Modern versions ==

v7 has been ported to the 386, information can be found [http://www.nordier.com/v7x86/index.html http://www.nordier.com/v7x86/index.html].

This was one of the more popular research versions to leave Bell Labs.

== Platforms ==

These are the known platforms to run Unix v6

=== PDP-11 ===
the [[PDP-11]] was the primary platform which Unix v6 was written on. All other v6's can trace themselves back to this version.

=== Interdata 8/32 ===
The [[Interdata 8/32]] was the first port to a 32 bit platform outside of Bell Labs.

=== Intel 80286 ===
There is a port by Szigeti Szabolcs to the Intel 80286 CPU, available in [http://www.tuhs.org/archive_sites.html the Unix Archive] under Other/V6on286. Requires a copy of [[MS-DOS]] to run.

=== i386 ===
There is a port to the x86 cpu, called xv6 used by MIT for an OS class. http://pdos.csail.mit.edu/6.828/2006/index.html You can download the source http://pdos.csail.mit.edu/6.828/2006/src/xv6-rev0.tar.gz

== Folk Lore ==

v6 Unix is perhaps famous because of the "[[Lions book]]". [[John Lions]] ( bio: http://en.wikipedia.org/wiki/John_Lions ) wrote up an excellent disection of the unix kernel, and taught it in his OS classes. The book became *the* guide to the unix internals, and was photocopied over & over...

v6 is also important, because it was the first non AT&T port of unix, when it was ported to the Interdata 32b.

== How do I get this to run?! ==

Well you'll need a tape image, and an emulator or a PDP-11/Interdata 32b... I'd recommend [[SIMH]] and you can get v6 by looking for uv6swre.zip and iu6swre.zip, PDP-11 and Interdata versions respectfully.
