My 1992 FTP site

Don't believe any links, or email addresses. Almost all have disappeared. Notice the strange domain name for mathematics at Sydney.

We did not get to see the web until at least 1993 when Mosaic came out (though we had to use Chimera on the Appollos). I haven't found my first email but I think it was around 1985 when I went to conferences announcing the importance of email, in particular to us in Australia. Hard to remember those times.

      SYDNEY CATEGORY THEORY SEMINAR 
      SYDNEY CATEGORIES IN COMPUTER SCIENCE SEMINAR
      Category theory material
         Available by Anonymous FTP
            from maths.su.oz.au


This file is README in the sydcat directory of maths.su.oz.au,
129.78.68.2, accessible by anonymous ftp.

The sydcat directory is for FTP distribution of recent publications, programs,
seminar listings and other material of the Sydney Category Theory Group, and the 
Sydney Categories in Computer Science Group.  These groups consist 
of mathematicians and computer scientists and students at the University 
of Sydney and Macquarie University, Sydney, Australia,
including the following:

 Murray Adelman murray@macadam.mpce.mq.edu.au
 Brian Day
 Robbie Gates   gates_r@maths.su.oz.au
 Amitavo Islam   islam_a@maths.su.oz.au
 Mike Johnson   mike@macadam.mpce.mq.edu.au
 Giulio Katis   katis_p@maths.su.oz.au
 Max Kelly   kelly_m@maths.su.oz.au
 Stephen Lack   lack_s@maths.su.oz.au
 Mark Leeming   leeming_m@maths.su.oz.au
 Stephen Ma   ma_s@maths.su.oz.au
 Wafaa (Moynham) Khalil  moynham_w@maths.su.oz.au
 Wesley Phoa   
 Usha Sridhar   sridhar_u@maths.su.oz.au

==========================Instructions======================================

FTP LOGIN.  Give the following commands.

 ftp maths.su.oz.au
Login: anonymous   (if you don't have an account on maths)
Paswd: yoursurname   (though any string will work)
 bin    (if you are retrieving a .dvi file)
 prompt off   (if you want no ? prompts from mget)
 cd sydcat   (change directory to _public/sydcat
 ls -lt    (see what's there, most recent first)
 mget filename-1 ... filename-n (e.g.   mget catcurrent.Z)
 quit    (exit from FTP)


DVI.  If you wish to print paper, calg say, retrieve calg.dvi and
associated .eps and .sty files from the subdirectory calg (cd calg first).
You must first give the bin command to ftp since .dvi files are not 
text files.  You will then need a dvi to postscript converter
which will include the .eps files. Print the resulting postscript file
on your host.

PROBLEMS.  If you have problems in either retrieving or compiling
papers, please contact Bob Walters.

NOTE.  Please note that the IP satellite link between Australia and the rest of the
world is saturated most of the time.  Large file transfers to non-Australian
sites should be spaced out, and should preferably take place between the
hours 2300 and 0800 local Eastern Australian time (the local time appears in
the ftpd banner at connection).

   Sydney Category Seminar
   Not being currently maintained.

programs/kan_1.0 A directory containing source and input files for
   kan (vers 1.0)  (Sean Carmody, Craig Reilly, Bob Walters)
 
     An implementation of the algorithm developed in 1990 by 
   Carmody & Walters to compute (finite) left Kan extensions 
   is now operational (programmed by Reilly and Carmody).

     There are also some sample input files as well as a file 
   called KAN.info which gives further details of the program
   and one called README which describes the sample input files. 
   If you experiment with the program, we would be very interested 
   to hear any comments or suggestions (especially with regards 
   any bugs which you -- hopefully won't -- find).
                                                 
     Future versions of the program will include a more 
   standardised i/o format, and will renumber the elements of 
   the output sets will be of the form {1,2,..,n} (a set which 
   may currently be given as {1,3,7} would become {1,2,3}).

   before it was properly documented.
