4.3 BSD

4.3 BSD
Logging into a 4.3 BSD system
Type:	Multitasking, multiuser
Creator:	CSRG, University of California, Berkeley
Architecture:	VAX, Tahoe theoretically portable
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-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" platform, based on a Motorola 68k processor. No one has any idea what this Tahoe computer is, as it completely disappeared off the face of the planet shortly after.

4.3 BSD-Reno

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

4.3 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.

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?

• 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
