The purpose of setting up CAP on GitHub is to build an AppleTalk
protocol stack for OS X 10.6 and newer that is compatible with
Classic Mac OS. That is, AFP-version up to 2.x and transport via DDP
(despite Apple removing DDP from OS X since 10.6).
This will enable AppleTalk networking with emulated machines running
Classic Mac OS as well as printing on non-IP, AppleTalk-only printers.

CAP Distribution 6.0, Patch Level 198 + 'asip1', March 1999
In 'CAP.faq' it is stated that the following interim patches are
available for download from munnari.OZ.AU and can be reversed once
patch 199 is completed:
asip.patch - AppleShareIP support
cicon.patch - Color Desktop Icon support
extnd.patch - Extended volume size support
desktop.patch - Desktop tool color icon support
It appears that patch 199 has never been released and the interim
patches are not available anymore at munnari.OZ.AU.
They are, however, available for download at
ftp://iubio.bio.indiana.edu/util/cap/ (log in as guest)
with the first patch substituted for a fixed version called
In this therefore unofficial, though fully patched version of CAP 6.0
these patches have been applied in the required, above stated order on
top of the patches 001 to 198.

CAP was written for BSD 4.2 Unix and derivatives. CAP implements a
library containing a portion of Apple Computer's AppleTalk protocols.
In order to use this package you may need an AppleTalk/Ethernet bridge
(e.g. Shiva FastPath, Webster MultiPort Gateway). CAP includes a number
of applications that can be used to print to a LaserWriter, spool for a
LaserWriter, and act as Unix based AppleShare compatible file server.
CAP also includes a number of sample programs and contributed software.
CAP library routines are structured, for the most part, the same as
the Apple routines described in "Inside AppleTalk" and "Inside
LaserWriter." Refer to the Apple documents and the procedure comments
for a complete description of the routines and how to call them.
Bill Croft's original work in this area provided the inspiration for CAP.
o CAP as originally shipped needs a gateway capable of supporting
IPTalk (the transmission of AppleTalk DDP packets inside IP UDP packets)
to translate (gateway) IPTalk packets to/from EtherTalk or LocalTalk.
Suitable candidates include ...
* Webster MultiPort Gateway
* Cayman Gatorbox
* Shiva FastPath
* Cisco Router
o This CAP version supports Native EtherTalk, UAR (Phase 1 or Phase 2) and
Kernel AppleTalk, UAB (Phase 1) on certain hosts. A gateway as listed
above is only required to access LocalTalk services.
o baseline host system: Ultrix 2.0-1. Most will work under BSD 4.2,
BSD 4.3, Ultrix 1.0-1.2, Sun OS 3.2 or higher, ACIS 4.2, A/UX, IBM
RISC 6000, IRIS/IRIX, HP/Apollo Domain (BSD environment), OSF/Alpha,
386/BSD, FreeBSD and other systems with BSD like networking
facilities with varying levels of functionality. Under certain
systems, only portions will work.
CAP can be obtained by anonymous FTP from
Please choose an appropriate site and an off-peak time for the transfer.
The patches are available individually or as the files "patches.1-100.tar.Z",
"patches.101-126.tar.Z", "patches.127-143.tar.Z", "patches.144-154.tar.Z",
"patches.155-162.tar.Z", "patches.163-182.tar.Z" & "patches.183-192.tar.Z".
Additionally, for new users, a partially patched source file is available
as "cap60.pl100.tar.Z" (beware: the file cap60.tar.Z is totally unpatched).
To make the process of patching easier, you should get the 'patch' utility
written by Larry Wall, it is normally available from sites that archive
comp.sources.unix in volume7/patch2 and at GNU archive sites as
patch-2.1.tar.gz (which requires gzip-1.2.2.tar for unpacking).
For each of the patches, run 'patch -p < cap60.patchNNN' from the top level
cap60 directory, for example, in csh
foreach i (cap60.patches/cap60.patch*)
patch -p < $i >>& /tmp/patches
and check the /tmp/patches file for patching errors (look for the strings
"rej", "failed", "offset", "fuzz" - should be none). To remove the *.orig
files that patch leaves behind (containing the original version of the file),
run 'make spotless' from the top level directory (note that spotless also
removes all makefiles so gen.makes needs to be run to regenerate them).
There is no CAP mailing list. Instead, notices and information about
CAP are posted to the mailing list info-appletalk which is gatewayed
with the USENET news group comp.protocols.appletalk. If you don't
have access to comp.protocols.appletalk and have access to the
ARPANET, you can get on the mailing list by sending mail to
Information about CAP and related UNIX AppleTalk packages is available
via the World Wide Web using
The CAP FAQ (Frequently Asked Questions) file is available via FTP
from munnari.OZ.AU as the file
Important documentation resides in:
doc/install.ms - stepwise installation document: assumes
you have read NOTES and this document
doc/print.cookbook - simple steps to implement CAP printing
man/* - UNIX manual entries for the various CAP programs
NOTES - installation notes: READ THIS BEFORE STARTING INSTALLATION
PORTING - notes on porting CAP to machines it doesn't know about
What's in CAP
The Columbia AppleTalk Package consists of a number of libraries, a
number of programs, and associated documentation. Following is a list
of the main parts along with a brief description.
o NOTES for a general overview of installation and some overview material.
o PORTING for information about making CAP work on systems not listed
netat - general header files used by various parts of CAP
man - man pages for some of the programs
doc - documentation
lib/cap - main appletalk libraries: ASP, PAP, ATP, NBP, DDP
lib/afp - generic AppleTalk Filing Protocol (AFP) routines
lib/afpc - AFP client libraries
lib/xenix - compatibility routines for XENIX use
etc - support programs: only atis - support program for NBP
extras - code and materials not necessarily related to AppleTalk
samples - sample programs: allow simple interaction with lw, appleshare
server, etc. See README there.
contrib - contributed programs
support - alterative LAP delivery support, Native EtherTalk,
Kernel AppleTalk and UAB.
applications - main applications.
The following programs in applications are in regular use at Columbia
and are a main part of the reason we work on CAP:
papif - UNIX lpd "input" filter for spooling to appletalk
- also includes sample "output" filter and printcap entry
- Note: this is a very bare bones filter
lwsrv - Simple LaserWriter spooler suitable for extension
aufs - AppleTalk Filing Protocol Unix File Server
NOTE: You must have the AppleShare 1.1 or 2.0 client code installed in
your Macintosh to use this. You must obtain this from Apple -
we do not and do not plan to supply this. The client code is
a lot of work and Apple's already done an excellent job here.

Hasn't been througly checked out on any system except Ultrix 2.0 & SunOS.
It it known to have run or should be able to run under: BSD 4.2, BSD
4.3, Ultrix 1.0, 1.1, 1.2, 2.2, Sun OS 3.2 or higher, Pyramid's Unix
under the BSD universe, ACIS 4.2 or 4.3 for the IBM RT PC, A/UX, HP-UX
for the series 9000 (release 6.0), Convex Unix V6.1, Sequents, IBM AIX
on the RISC 6000, Silicon Graphics IRIS/IRIX, HP/Apollo Domain (BSD),
OSF/1 Alpha, 386/BSD, FreeBSD and the Encore Multimax.
LAP - will probably never be implemented
DDP - don't try to use it directly
Documentation - in shorter supply than it should really be
a) Complete NBP - completed.
b) Complete PAP - completed.
c) Complete ATP - completed.
d) Complete DDP - essentially completed, but some minor parts missing.
e) Complete ASP - completed.
f) Start AFP - client side needs to be redone, server side okay.
g) Start ZIP work. KIP modified to allow under rev 1/88.
h) Start RTMP work. Not need under KIP.
i) miscellanous other fixes and cleanup
Thanks to the User Services staff at Columbia University Center for
Computing Activies for patiently testing all the broken software that
was foisted on them as "working" with special thanks going to:
Rob Cartolano for testing Aufs beyond the call of duty
Alan Crosswell for making papif die more than anyone else and
letting me use his RT.
Lisa Covi and Jeff Eldredge for living with the software in
our Mac MicroLab
Mark Kennedy, Tom Chow, and Richard Sacks for giving Charlie
