I know there was a discussion a while back about whether 11/73s
(93s, 83s, 53s) were "dec.micro" or not. My (non-ECC;-) memory recalls
that they are, so i'm posting this announcement here as well as
comp.bugs.2bsd (the front panel of my 11/73 says Micro-Pdp on it

Second Distribution of Berkeley PDP-11 Software for UNIX
(Revised January 1991)
The USENIX Association is pleased to announce the distribution of
a new release of the "Second Berkeley Software Distribution"
This release will be handled by USENIX, and is available to all
V7, System III, System V, and 2.9BSD licensees. The Association will
continue to maintain the non-profit price of $200. The release will
consist of two 2400 ft. 1600 bpi tapes or one TK50 tape cartridge
(approximately 80M) and approximately 100 pages of documentation.
If you have questions about the distribution of the release, or
require 800 bpi tapes, please contact USENIX. USENIX's address and
phone number is as follows:
2560 Ninth St. Suite 215
Berkeley, CA 94710

This release is in celebration of the 20th anniversary of the
PDP-11! Work has been ongoing since the release of 2.10.1BSD in Janu-
ary 1989. This release incorporates all fixes and changes posted to
the USENET newsgroup comp.bugs.2bsd since 2.10.1BSD was released.
Present in this release are several more missing pieces from the
o 1) the kernel logger (/dev/klog)
o 2) the namei cache and argument encapsulation calling
o 3) readv(2)/writev(2) as system calls rather than
o 4) shadow password file implementation (the May 1989 4.3BSD
o 5) a TMSCP (TK50/TU81) driver with standalone support (boot-
block and standalone driver)
o 6) Pronet and LH/DH IMP networking support
o 7) the portable ascii archive file format (ar, ranlib)
o 8) the Unibus Mapping Register (UMR) handling of the network
was rewritten to avoid allocating excessive UMRs.
o 9) the necessary mods to the IP portion of the networking
were made to allow traceroute (which is present in 2.11BSD)
o 10) long filenames in the file system
This last addition is the reason a coldstart kit is necessary.
The 4.3BSD on-disk directory structure has been ported (along with the
utilities that know about on-disk directories via the raw filesystem:
fsck, ncheck, icheck, dcheck, etc.) and is not compatible with previ-
ous versions of UNIX for the PDP-11.
A limited amount of filesystem backward compatibility with ear-
lier versions of 2BSD (2.9BSD, 2.10BSD and 2.10.1BSD) is present in a
version of dump(8) which can read old filesystems. The disk partition
sizes have not changed from 2.10.1BSD (the urge to standardize the
haphazard partition sizes was suppressed in the interest of backwards
compatibility). The restor(8) utility automatically converts old dump
tapes to the new format on input.
The constant MAXNAMLEN is now 63 instead of 14. While it is pos-
sible the limit could be higher, with MAXPATHLEN at 256 a MAXNAMLEN of
63 was judged sufficient.
MANY other fixes and changes have also been made, see the
``Changes To The Kernel'' document which describes the changes made to
both the kernel and the application programs.
