This Version:	4.3BSD-Reno (1990) 4.3BSD-Quasijarus0c (2004)
Date Released:	1986

4.3 BSD follows 4.2 BSD, with TCP/IP networking, an improved filesystem, in -Tahoe, partial cross-platform capability, and in -Reno, a significant move toward POSIX compliance. This is a favourite with hobbyists, as being open source there are no licencing concerns and the tape data is freely available online, and it runs very well in SIMH. 4.3 BSD is also quoted as being the The Greatest Software Ever Written.

``The single Greatest Piece of Software Ever, with the broadest impact on the world, was BSD 4.3. Other Unixes were bigger commercial successes. But as the cumulative accomplishment of the BSD systems, 4.3 represented an unmatched peak of innovation. BSD 4.3 represents the single biggest theoretical undergirder of the Internet. Moreover, the passion that surrounds Linux and open source code is a direct offshoot of the ideas that created BSD: a love for the power of computing and a belief that it should be a freely available extension of man's intellectual powers--a force that changes his place in the universe.``

4.3 BSD

The first version of 4.3 BSD incorporates many performance fixes related to the release of 4.2 BSD. Many people have listed this piece of software as the single most important piece of software ever. Without doubt, it's responsible for influencing almost all operating systems that ever connected to the intenet, and it's TCP/IP stack was used for coutless other OS's. While not as feature rich as the other 4.3's it is known for being faster then 4.2 . However this version does *NOT* support the MicroVAX II that SIMH emulates, but rather the VAX-11/780.

This version seems to have been released on June 6th 1986. (dated from the GENERIC build directory in the kernel source tree.)

4.3 BSD+NFS Wisconsin Unix

This release dates around Jan 20 1987. It never seems to have made mainstream use, and I can only find a single site that ran it on the old UUCP network. This release is signifigant in that it incorporated the SunOS NFS code, and a few bits of SunOS to flesh it out. A few people from the University of Wisconsin went on to work for SUN so it's no surprise the ammount of Sun source in this release. This release is only for VAX's and runs under SIMH's 11/780 emulator just fine.

4.3 BSD-Tahoe

Tahoe follows up on 4.3 BSD in 1988 with plans to ditch the aging (ironically it would be around for 12 more years...) VAX platform with machine independence and a port to the "Tahoe" Power 6/32 platform. No one has any idea what this Tahoe computer is, as it completely disappeared off the face of the planet shortly after.

======================== 
     We are happy to send you  information  about  our  June 
1988  revision of the Fourth Berkeley Software Distribution, 
hereafter referred to as the ``4.3BSD tahoe''  distribution. 
The purpose of this release is to provide 4.3BSD support for 
the ``tahoe'' processor and to  get  feedback  on  some  new 
features  and facilities that we expect to include in future 
Berkeley releases.  This  distribution  is  not  a  standard 
Berkeley  release;  it  is  an  interim release intended for 
testing and evaluation rather than production use  by  naive 
users.  The distribution is available to users with licenses 
for the April 1986 4.3BSD release for the VAX. 


What is the 4.3BSD Tahoe Release? 


     The distribution consists of one 6250 BPI or three 1600 
BPI magnetic tapes, certain updated manual pages, and a copy 
of ``Installing and Operating 4.3BSD  on  the  Tahoe.''  The 
magnetic  tape(s) contain copies of source code and documen- 
tation for both the VAX and the tahoe, and binaries for  the 
tahoe.   On  the three-tape 1600 BPI set, parts of the user- 
contributed software are shipped as compressed  archives  to 
save space. 


     The primary purpose of this release is to provide  sup- 
port  for  the ``tahoe'' processor, the CPU used by Computer 
Consoles, Inc. (CCI Power 6/32, 6/32SX), and high end  lines 
of Harris (HCX-7 and HCX-9), Unisys (7000/40), and ICL (Clan 
7).  Support for this processor is derived from  the  4.2BSD 
system  done by CCI.  Support for new DEC equipment has also 
been added, including support for the 8250 BI-based CPU  and 
the KDB-50 BI disk controller from Chris Torek, and the QVSS 
and QDSS display drivers for the MicroVAX II, contributed by 
Digital Equipment Corporation.  We expect to provide support 
for  both  the  VAX  and  the  tahoe  processors  in  future 
releases. 


The  major  new  software  systems  include  the   following 
features: 


+    The TCP and IP code is the same as that  recently  made 
     available  via  the  ARPANET  and  Usenet.  Several new 
     algorithms  are  used  in  TCP,   in   particular   Van 
     Jacobson's slow start and dynamic window size selection 
     algorithms and Phil Karn's modification to  the  round- 
     trip   timing   algorithm.    These   changes  increase 
     throughput and reduce  congestion  and  retransmission. 
     Several  fixes  were made in the handling of IP options 
     and other gateway support. 


+    The file system has been generalized to remove the lim- 
     its on the maximum number of inodes per cylinder group, 
     cylinders  per  cylinder  group,  and  number  of  dis- 
     tinguished  rotational  positions.  The kernel and file 
     system utilities operate normally on both new  and  old 
     format  file  systems;  old  kernels treat the new file 
     systems as read-only.  This change allows better utili- 
     zation  of  newer  disks with larger numbers of sectors 
     per cylinder. 


+    The system has full support for disk labels  that  con- 
     tain  disk geometry information and partition layout on 
     each disk.  Labels are used on disks using  the  hp  or 
     uda  drivers  on  the VAX (hp or ra disks) and all sup- 
     ported disks on the tahoe.  The  utility  to  read  and 
     write  disk  labels can be used with the system running 
     multiuser; the labels are used and updated as appropri- 
     ate by newfs, bad144, the kernel and the bootstrap pro- 
     grams.  Basic file system parameters are stored in  the 
     label  so  that  fsck can locate alternate superblocks. 
     The filesystem and  newfs  use  additional  information 
     about  the disk geometry that is now available, such as 
     track-to-track skew. 


+    A new general-purpose dynamic memory allocator has been 
     written  that can be used by all the kernel subsystems. 
     The design of this allocator takes advantage  of  known 
     memory  usage  patterns  in  the  UNIX  kernel, using a 
     hybrid strategy that is time-efficient for small  allo- 
     cations  and  space-efficient  for  large  allocations. 
     This allocator replaces most  of  the  previous  memory 
     allocation  interfaces  with  a  single easy-to-program 
     interface, results in  more  efficient  use  of  global 
     memory   by  eliminating  partitioned  and  specialized 
     memory pools, and is quick enough that  no  performance 
     loss  is  observed relative to the previous implementa- 
     tions.  Most of the kernel  memory  allocation  is  now 
     done using this allocator. 


+    The source code has been reorganized to ease support of 
     multiple machine types. 


+    The Olson/Harris/Elz timezone implementation  has  been 
     added to the system. 


+    Numerous bug fixes  and  enhancements  have  been  made 
     throughout  the  system,  including new versions of the 
     nameserver  named  and  the  routing   daemon   routed. 
     Several years' backlog of bug fixes have been applied. 


+    We have started a process of identifying  the  code  in 
     the  4.3BSD  distribution that is not derived from AT&T 
     code.  The copyrights in this code have been changed to 
     indicate that it may be freely distributed if the copy- 
     right notice is retained and that due  credit  for  its 
     origin  is  given  to  The Regents of the University of 
     California.  Over 1000 files have  been  identified  in 
     this distribution.

4.3 BSD-Reno

Following up in 1990 comes -Reno, with a significant thrust toward POSIX compliance, (with an associated increase in code size).

        4.3BSD-Reno is available!  The attached is the cover letter

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 


Dear Colleague: 


     We are happy to send you information about  our  June,  1990 
test  release  of  the  Fourth  Berkeley  Software  Distribution, 
4.3BSD-Reno.  This release represents an  intermediate  point  in 
the  development of 4.4BSD; several new facilities have been com- 
pleted and are ready for external use, while other new facilities 
slated  for the 4.4BSD release have not yet been integrated.  Our 
goal in making this release available is to get feedback  on  any 
problems  in  the design or implementation of the new facilities, 
as well as to allow adventurous sites  to  gain  experience  with 
these portions of 4.4BSD. 


     This distribution is NOT intended to be used  on  production 
systems;  nor  is  it intended for sites without sufficient local 
expertise to find and fix any problems that are encountered.   It 
is  intended to be used to provide an advance look at some of the 
facilities and interfaces that we will be distributing in 4.4BSD. 
We  are  interested  in getting feedback on the problems that you 
find and also any compatibility problems that you  anticipate  in 
trying  to convert your applications to run on this release.  The 
interfaces in this release will  change  before  the  release  of 
4.4BSD (at least in part based on feedback from this test group). 
Thus, you should not expect applications ported to  this  release 
to work unchanged on 4.4BSD. 


     Unlike past test releases, 4.3BSD-Reno is  being  made  gen- 
erally  available  to  4.3BSD  licensees,  and 4.3BSD-Reno may be 
redistributed and used in released  products  (within  the  usual 
licensing  constraints).   However,  you will have to upgrade any 
code that you use from 4.3BSD-Reno to the 4.4BSD code within  one 
year  of  the release of 4.4BSD.  We appreciate your help in this 
debugging effort and look forward to hearing  from  you.   Please 
send   your  comments  to  reno43-b...@okeeffe.Berkeley.EDU.   We 
regret that changes documents are not available; the next section 
outlines the major changes available in 4.3BSD-Reno. 


     The license to 4.3BSD-Reno is  simply  an  Addendum  to  the 
4.3BSD  License.   Sites without a 4.3BSD license may obtain both 
4.3BSD and 4.3BSD-Reno simultaneously, but  must  sign  a  4.3BSD 
license as well as the Addendum.  Contact the distribution office 
for 4.3BSD licensing information.  4.3BSD is  available  only  to 
sites with UNIX/32V, System  III, or  System  V  source  licenses 
with  AT&T.   We  are  actively working to decrease the amount of 
AT&T code in the system.  We expect that we will provide a subset 
of  4.4BSD  without  the  AT&T code to sites without requiring an 
AT&T license.  However, we are not prepared to make that determi- 
nation  for this release, so we are providing only tapes with the 
complete system at this time. 


     The enclosed information is designed to serve two  purposes. 
The first purpose is to acquaint you with the details of our dis- 
tribution so you can decide whether you would like to receive it. 
The second purpose is to tell you how to obtain our distribution. 


What is 4.3BSD-Reno? 


     The distribution consists of one 6250 bpi or three 1600  bpi 
magnetic tapes containing full sources and documentation plus one 
set of binaries.  You may specify VAX  and/or  Tahoe  (CCI  Power 
6/32) binaries. 


     The three major new facilities available in the  4.3BSD-Reno 
release  are the addition of ISO/OSI networking support, a freely 
redistributable implementation of NFS, and the conversion to  and 
addition  of  the  POSIX.1  facilities.  There are numerous other 
changes throughout the system. 


     The ISO/OSI Networking consists of a  kernel  implementation 
of  transport  class 4 (TP-4), connectionless networking protocol 
(CLNP), and 802.3-based link-level  support  (hardware-compatible 
with Ethernet*).  The session and  presentation  layers  will  be 
provided  outside  the  kernel by the ISO development environment 
(ISODE).  Included  in  this  development  environment  are  file 
transfer  and management (FTAM), virtual terminals (VT), a direc- 
tory services implementation  (X.500),  and  miscellaneous  other 
utilities. 


     A new virtual filesystem interface has  been  added  to  the 
kernel to support multiple filesystems.  Although generally simi- 
lar to Sun's vnode interface, the  Berkeley  interface  has  been 
structured  for  more efficient support of filesystems that main- 
tain state (such as the local filesystem).  In  addition  to  the 
local ``fast filesystem'', we have added an implementation of the 
network filesystem (NFS) that fully interoperates  with  the  NFS 
shipped by Sun and its licensees.  Because our NFS implementation 
was  implemented  using   only   the   publicly   available   NFS 
specification, it does not require a license from Sun to  use  in 
source  or binary form.  By default it runs over UDP to be compa- 
tible with Sun's implementation.  However, it can  be  configured 
on  a per-mount basis to run over TCP.  Using TCP allows it to be 
used quickly and efficiently through gateways and over  long-haul 
networks.  We have also added a memory-based filesystem that runs 
in pageable memory,  which  allows  large  temporary  filesystems 
without requiring dedicated physical memory. 


     The quota system has been rewritten to support both user and 
group  quotas  (simultaneously  if desired).  Quota expiration is 
based on time rather than the previous metric of number of logins 
over  quota.  This change makes quotas more useful on fileservers 
onto which users seldom login. 


     The 4.3BSD-Reno distribution contains most of the interfaces 
specified  in the POSIX.1 system interface standard.  The biggest 
area of change is a new terminal driver.  The terminal driver  is 
similar  to the System V terminal driver with the addition of the 
necessary extensions to get the functionality  previously  avail- 
able  in  the  4.3BSD terminal driver.  4.3BSD-Reno also adds the 
POSIX job control interface, which is similar to the  4.3BSD  job 
control  interface, but adds a security model that was missing in 
the 4.3BSD job control implementation.  Other  additions  include 
POSIX  signals, FIFO's, and saved user and group identifiers.  We 
have been tracking the POSIX shell  and  utility  work  and  have 
included  prototypes of many of the proposed utilities.  Finally, 
we have converted about 80% of the libraries and header files  to 
be compliant with ANSI C. 


     Work has also progressed in several  other  areas.   Several 
important  enhancements  have  been added to the TCP/IP protocols 
including TCP header prediction and serial line  IP  (SLIP)  with 
header  compression.   The  routing  implementation has been com- 
pletely rewritten to use a hierarchical routing tree with a  mask 
per route to support the arbitrary levels of routing found in the 
ISO protocols.  The routing table also stores  and  caches  route 
characteristics  to  speed  the  adaptation of the throughput and 
congestion avoidance algorithms. 


     The Kerberos (version 4) authentication  software  has  been 
integrated  into  much  of the system (except NFS) to provide the 
first real network authentication on BSD. 


     The hardware supported by 4.3BSD-Reno is: 


+    VAX (86x0, 78x, 750, 730; MicroVAX II, 3200/3500/3600; 82x0) 


+    Tahoe (CCI Power 6/32, 6/32SX; Unisys 7000/xx; Harris  HCX7, 
     HCX9) 


+    HP 9000/300 series 


In addition, kernel support for the Intel i386  and  many  AT-bus 
peripherals  has  been  added  recently; contact the distribution 
office for a list of supported hardware if necessary. 


For this distribution, binaries will be available  for  only  the 
VAX  and Tahoe architectures.  The 4.4BSD distribution will prob- 
ably be available for all the  above  architectures  as  well  as 
several machines based on the MIPS processor. 


     The reason that this distribution  is  not  labeled  4.4BSD- 
alpha  is  because  it  does not contain several major interfaces 
that we plan to have  available  for  that  distribution.   These 
include: 


+    A  new  virtual  memory  system  using  the  mmap  interface 
     described  in  the 4.3BSD architecture document.  The inter- 
     face is similar to the interface shipped in several  commer- 
     cial versions of UNIX such as SunOS 4.0. 


+    Support for ISO Connection-Oriented Network  Service,  X.25, 
     TP-0. 


+    A new internal  network  layering  (``bstreams'')  combining 
     features of the current socket layering and of Streams. 


+    Fixes, tuning, fixes, documentation, and fixes. 


     This release does include several important structural  ker- 
nel  changes.  The most pervasive change is to eliminate the user 
structure fields u.u_error, u.u_u_r.r_val1, and u.u_ap by using a 
new internal system call convention: 
error = (*callp)(proc, args, retval); 


We are also reducing the use of other global variables  with  the 
intent  to  eventually  eliminate all references to the user area 
except for the per-process runtime stack.   Thus,  all  substruc- 
tures will eventually be referenced via the proc structure. 


     Another major change is the  introduction  of  a  new  sleep 
interface: 
error = tsleep(wchan, pri|PCATCH, wstring, timeout); 


The old sleep interface can be used  only  for  non-interruptible 
sleeps.  The tsleep interface can be used at any priority, but is 
only interruptible if the PCATCH flag is set.  When  interrupted, 
tsleep   returns   EINTR   or   ERESTART;  all  non-local  goto's 
(longjmp's) have been eliminated from the kernel. 


     Many data structures that were previously  statically  allo- 
cated  are  now  allocated dynamically.  These structures include 
the mount table, the vnode table, the name cache, and  the  quota 
structures. 


How to obtain the 4.3BSD-Reno release 


     All previous 4.3BSD licensees will be able  to  receive  the 
4.3BSD Reno release simply by executing the steps outlined below. 
4.2BSD licensees who have not yet  upgraded  to  4.3BSD  will  be 
required  to  do so as well as following the steps outlined below 
for the Reno distribution.  For further information  on  ordering 
the standard 4.3BSD distribution, contact our distribution office 
at the address given below. 


     Because we are a research and development  organization  and 
not  a  commercial  organization,  we  make  our research results 
available for a fee which covers only our costs for the distribu- 
tion.   We distribute only the whole system and cannot send indi- 
vidual pieces of the system.  Because the software is distributed 
``As Is'' and is partially derived from licensed material, we are 
required to have a formal license arrangement with each organiza- 
tion to which we distribute. 


     Specifically, we must receive  from  your  organization  the 
following material before the distribution can be sent: 


+    Two appropriate signed Addenda for the Reno distribution  if 
     you  are  a  4.3BSD  licensee.  Add  to that the appropriate 
     Addendum to receive the upgrade if you are a  4.2BSD  licen- 
     see.  For new licensees, two executed copies of the Berkeley 
     License Agreement  (4/86)  with  the  appropriate  Addendum, 
     i.e.,  for foreign or US government sites, plus the Addendum 
     for the Reno distribution.  We require  two  copies  of  all 
     Agreements/Addenda with original signatures, one of which is 
     returned to the Licensee.  The name of the  organization  on 
     the  Addendum  No.  Three  must  be  the  same as that which 
     appears on the Software  Agreement  with  AT&T  (or  Western 
     Electric).  The  Addendum No. Three must be signed by a duly 
     authorized person who holds a position that is at  the  same 
     level  or  a higher level of authority as that which appears 
     on the AT&T Software Agreement. Please  have  this  person's 
     name  and  title typed in the available space in addition to 
     the signature. 


+    A check from a U.S. bank for $495.00 U.S. (for a single 6250 
     BPI  tape  of  4.3BSD-Reno)  or  $595.00 (for three 1600 BPI 
     tapes of  4.3BSD-Reno)  payable  to  ``The  Regents  of  the 
     University  of California'' must be received before the dis- 
     tribution can be sent.  If you must issue a Purchase  Order, 
     please  issue one that is blank-backed.  If this is not pos- 
     sible, insert and initialize in the  body  of  the  Purchase 
     Order  the  following  clause: ``The terms and conditions of 
     this Purchase Order are not accepted by The Regents  of  the 
     University  of  California.   The  revised  Berkeley License 
     Agreement (4/86) governs.''  For  4.2  licensees  that  have 
     updated  to 4.3BSD, substitute ``The terms and conditions of 
     this Purchase Order are not accepted by The Regents  of  the 
     University  of  California.   The  revised  Berkeley License 
     Agreement (6/83) and Addendum Number Three govern.'' 


+    A completed Site Information Form.  The distribution  itself 
     will be sent to the technical contact.  The site information 
     is kept confidential and is for our use in identifying sites 
     with  specific  configurations.   Please note that we cannot 
     ship to post office boxes; therefore, please have the techn- 
     ical contact's address supplied without use of a post office 
     box. 


     A checklist is  included  to  aid  you  in  assembling  this 
material.  All the above material must be sent to: 


        Distribution Coordinator 
        Computer Systems Research Group 
        Computer Science Division, EECS 
        University of California 
        Berkeley, California 94720 


Once all these items have been received and are in proper  order, 
the  distribution will be sent to the technical address indicated 
on the Site Information Form that you provided  when  you  placed 
your  order; we cannot provide delivery dates.  Once the material 
is assembled and packaged, the distribution is shipped by commer- 
cial carrier.  Order of shipment will be based on time of arrival 
of the properly completed paperwork.  Because of the differential 
in  costs  of  shipping  outside  the  United States, we ask that 
organizations beyond the North American continent pay the collect 
shipping charges. 


     The most expedient way to insure that your full distribution 
is  sent as quickly as possible is to include in a single package 
the signed appropriate Addenda  (without  modification)  for  the 
Reno  distribution  plus any other necessary signed legal papers, 
depending on your licensing status, the appropriate  check  prop- 
erly made out to ``The Regents of the University of California,'' 
and a completely filled-out Site Information Form,  and  to  send 
this single package to the address noted above. 


Large Organizations 


     Many large organizations have  multiple  entities  that  act 
independently  from  one  another  and are licensed independently 
from AT&T.  Others have the parent organization licensed by  AT&T 
and  copies of the software distribution sent to each independent 
entity. The Berkeley License Agreement must be executed with  the 
organization holding the appropriate AT&T Software Agreement. 


     If your organization has an AT&T license and chooses not  to 
redistribute  internally,  please  contact  us  for a copy of the 
letter of authorization to be executed by the parent company. 


Special Cases 


     University of California Sites.  If you are a  part  of  the 
University  of California, and do not already have an AT&T source 
license for your CPU, you must use the following  procedure:  ask 
Pam  True  (415)  642-6348 at Berkeley Campus Materiel Management 
for an application for an additional CPU authorization under  The 
Regents of the University of California's Software Agreement with 
AT&T.  We will receive the completed  application  from  Materiel 
Management.   If  you have previously obtained a Berkeley License 
for your CPU or have an AT&T source license for your CPU, you  do 
not need to contact the Materiel Management Office. 


     In all cases, the following items must be sent to  the  Com- 
puter  Systems Research Group: 1) a letter signed by the Director 
or Head of Department requesting 4.3BSD-Reno,  stating  that  you 
have  read and understood the Berkeley License Agreement and that 
your organization will abide by it, 2)  an  IOC  for  $495.00  or 
$595.00 (1600 BPI), and 3) a Site Information Form if the contact 
information has changed. 


     DARPA Sites.  The research on which  the  Berkeley  Software 
Distributions  are  based  has  been  sponsored by DARPA (Defense 
Advanced Research Projects Agency).  Provision has been made  for 
prepayment  of  distribution  costs  for  a  few designated DARPA 
sites.  In place of the check for $495.00 or $595.00, you  should 
include  a  letter from your Program Manager stating that you are 
designated as such a site.  However, you  must  comply  with  all 
other requirements in applying for the distribution. 


A Special Note 


     The procedures and  rules  set  out  in  this  document  are 
University  and  AT&T  constraints that must be followed in order 
for the distribution of software to be  possible.   The  Computer 
Systems  Research Group has no control over these constraints and 
must reject your application if  material  submitted  is  not  in 
order. 


If You Have Read Everything and Still Need Help 


     If you have questions  about  the  licensing  process  after 
reading this letter, you may call the distribution group at (415) 
642-7780, write to them at the address above, or contact them via 
electronic mail at bsd-d...@Berkeley.EDU or ucbvax!bsd-dist. They 
will not be able to answer technical questions. 


                         Sincerely yours, 


                         Mike Karels 
                         Computer Systems Research Group

4.3 BSD-Quasijarus

http://ifctfvax.harhan.org/Quasijarus/

"Quasijarus is a project of the International Free Computing Task Force (IFCTF) led by Michael Sokolov to indefinitely continue the maintenance, support, and further development of the classic line of Berkeley UNIX on the classic VAX hardware."

A fork of 4.3 BSD-Tahoe to maintain it, for the VAX architecture. This is often the distribution that hobbyists will install on real or, especially, emulated VAXen.

How do I get this to run?!

The Unix Heritage Society's archives have copies of most 4-BSD variants http://minnie.tuhs.org/TUHS/ However, they're not immediately in ready-to-use-in-SIMH tape format. We should get a repository of SIMH-ready tape images up here.

4.2 & 4.3BSD Reno are in ready to run formats on sourceforge

The 4.3 RENO has built in networking so you have limited internet access (Using SLiRP)

SIMH Installation instructions

• Installation instructions for 4.3 BSD can be found here
• Installation instructions for 4.3 BSD +NFS Wisconsin Unix can be found here
• Installation instructions for 4.3 BSD TAHOE can be found here
• Installation instructions for 4.3 BSD RENO can be found here
• Installation instructions for 4.3 BSD Quasijarus 0c can be found here

What Runs?

4.3 BSD-Reno includes a large amount of POSIX which dramatically improves compatibility with many modern and older *nix packages. A lot of people don't like -Reno as its embracing of POSIX is rather treasonous to the BSD ideal. So what compiles on 4.3 BSD-Tahoe or its maintained version, -Quasijarus?

Quasijarus

• gcc-2.8.1x see ftp://ifctfvax.harhan.org/pub/unix/apps/gcc
• perl 4! I haven't really tried hard enough to get perl 5 to compile, might work with gcc...
• pdksh - right out of the box! http://www.cs.mun.ca/~michael/pdksh/
• A lot of software from that era, including early versions of many GNU programs, (emacs-18!) and so on
• A copy of Zork is also included in the distribution.

U Wisconsin

• bash 1.14.7
• bash 2.0
• bison 1.25
• gcc 1.42
• gcc 2.4.5
• gzip 1.2.4
• irc 2.8.21
• make 3.75
• unzip 522
