Subject: Netiquette
 
Behaviour on the net:
  Behaviour on the net should be based on respect for other readers. If
  you follow this guideline, the net can be a very powerful tool for
  useful information.
 
  Try to reduce the amount of material posted and keep your articles
  short. This helps to save on phone bills throughout the entire
  Usenet community and saves time when reading the voluminous Amiga
  news groups.
 
  Try to avoid posting your view on an issue that has no "correct"
  answer. An example of this is the "my machine is better than your
  machine" discussion that often flares up in the microcomputer
  newsgroups. If you must express your point of view, please indicate
  that you would like to continue the discussion via mail, so as not to
  harass other readers that are not interested in the subject.
 
  Please do not make derogatory postings (aka. flames).  Do not subject
  other readers to these childish tit for tat postings.  Have fun via
  mail.
 
Newsgroups:
  There are currently four official groups dedicated to the Amiga. Here
  is a brief description of each of them and what kind of articles they
  should contain:
 
  comp.sys.amiga - This newsgroup is for general discussion of Amiga
    related news, software and hardware.
 
  comp.sys.amiga.tech - This newsgroup is for the technical discussions
    about programming the hardware and software of the Amiga.
 
  comp.sources.amiga - This newsgroup contains the sources to freely
    redistributable programs posted exclusively by the moderators.
 
  comp.binaries.amiga - This newsgroup contains the binaries related to
    the programs in the sources group. This group can also only be
    posted to by the moderators.
 
  Please adhere to these classifications and post your news to the
  appropriate group. See the MOD section (enter g MOD) in this posting
  on how to post to and receive from the moderated groups.
 
Mail:
  If you would like to reply to an article posted by someone else and
  you do not think your reply is of value to others on the net, then
  please send mail to the poster instead of posting a reply. This
  helps reduce the amount of news sent each day and improves the ratio
  of signal to noise in the newsgroup. When in rn type 'r' to reply via
  mail. Type 'R' to include a copy of the poster's article.
 
Following up:
  If you do feel the reply is important enough for everyone on the net,
  then please keep your posting small. In rn, type 'f' to follow up,
  and 'F' to include a copy of the poster's original article. Please
  trim the included article down to only the relevant parts, so that
  people are reminded of the gist of the original without having to
  re-read the entire text.
 
Posting original material:
  Original material is preferred, as it offers something new for the
  readers. However, if you post an request for information or software,
  please include a request for mail instead of a news followup.  Again,
  this is to help reduce the amount the reader must go through each day.
 
Cross posting:
  Cross posting to many newsgroups takes no more room or time than
  posting to one newsgroup. However, many more people see your article,
  and the above rules become more critical. If you do cross post,
  please realize that people from any of the groups may followup to
  your article. By default, most news programs post to all the original
  newsgroups. If you think the replies to your article will only be
  relevant to one group, please use the Followup-To line to indicate
  that the named news group should be used for replies. Also, if you
  are replying to someone else's cross-posted article, please edit the
  Newsgroups line to indicate only the groups to which your reply is
  relevant.
 
Remember to have respect for your fellow netters and you will gain the
most from Usenet.

Subject: how to retrieve programs from the moderated groups
 
Saving a file:
  To get a program, you must save the article you are reading.
  Under rn type:
 
  s filename
 
  while reading the article with the program in it. The 'filename' can be
  any name you choose for it. This will save the program under the
  default directory News. Thus the file will be News/filename.
 
  Once you have saved all the programs, you should then use an editor such
  as vi to delete all the lines until the one that says, "delete all lines
  up to this one."
 
Shar:
  Most programs the moderators send out are shared together. This is a
  special way of binding many text files together to make them easier to
  handle.
 
  You now have various choices. There is an unshar program on the Amiga
  (Fish 97) or you can use the standard Unix Bourne shell 'sh' to unshar
  them. The Unix 'sh' should work with any file the moderators send
  across. From unix, type:
 
  sh filename
 
  It is recommended you put this file in its own directory to contain all
  the file that sh generates.
 
Uudecode:
  Some files are binaries that have been 'uuencoded'. This is because the
  connection between Unix machines can only handle text characters, and not
  certain binary characters. To get around the problem, these binary files
  are encoded into text using uuencode. Uuencoded files usually have a .uu
  or a .uue extension so that you can recognize them. To uudecode a file
  type:
 
  uudecode filename
 
  It is recommended that you do your uudecoding on the Amiga. This way,
  there are less errors involving file formats on your host machine that
  are different from the Amiga's own file format. There is a version of
  uudecode for the Amiga on Fish 38.
 
Arc/zoo:
  You might notice that .arc or .zoo files are produced by uudecode. These
  files are actually many files glued together and compressed to conserve
  space. To extract files from a .arc file, type the following on the Amiga:
 
  arc x filename
 
  To extract files from a .zoo file on the Amiga:
 
  zoo x// filename
 
  There is a version of arc on Fish 70 and a version of zoo on Fish 136.
  (Earlier version of arc: Fish 40. Earlier versions of zoo: Fish 87
  and 108)

Subject: How to post to comp.[sources|binaries].amiga
 
   I'll give you a quick rundown of the various ways to make submissions in
preferred order..
 
   1) make up some postings and post them to the proper groups -- since these
      groups are moderated, the posting will get sent via mail to the
      moderator(s).  Preferred.  Helps us a bit if we forward the submission
      to a different machine.
   2) send mail to the mail aliases amiga-sources-request or
      amiga-binaries-request.  Next best -- but be sure the size of the file
      will go through mail unscathed (100K or less is usually ok).  (BTW, the
      aliases are always directed to the right person to receive the
      submissions)
   3) send mail directly to the moderators.  Same warnings as above, but also
      be sure to send it to the right person -- if you get it wrong, your mail
      might never be heard from again.
 
   Since all these ways use mail, the data transmission is equally reliable
between them.  The main difference is ease of submission, and what happens
at our end.
 
   The current moderators are:
                 Bob Page - page@swan.ulowell.edu

Subject: How to get Fish disks.
 
 
WHAT'S AVAILABLE
----------------
 
There are "do-nothing-useful" examples of various capabilities of the
AMIGA, real development tools, editors, languages, games, and other
odds & ends.  Also included are machine readable form of many of the
examples (received directly from C-A sources) out of the official
AMIGA manuals, including the ROM Kernel Manual.
 
 
HOW TO OBTAIN DISKS
-------
 
First, check with your local dealers and user groups.  Many already have
the earlier disks.  Since these disks can be copied freely, and widespread
distribution is encouraged, they propagate out to central distribution
points fairly quickly.
 
If you just can't wait, or can't find copies locally, I am willing to
make these disks available for the cost of media, mailing materials,
postage, and miscellaneous expenses (like wear and tear on my drives).
My goal is to get as much software as possible into the hands of people
that can use and enhance it, and make the AMIGA the success it deserves
to be.
 
Generally, each disk contains all source necessary to recreate the
executables provided.  All programs are currently compiled with the
latest Lattice C and/or Manx C compiler available at the time of release.
In a very few cases (noted in the description) the code will not compile
or run for some reason, but was considered interesting enough to include
anyway.  Almost all executables are known to run on the latest
kickstart/workbench combination available at time of release.
 
Disks are typically 85 to 95 percent full.
 
HOW TO ORDER
------------
To order, send a list of the disks you want, and $6 per disk ($5 per disk
for 10 or more disks), in U.S. funds, to:
 
        Fred Fish
        1346 W. 10th Place
        Tempe, Arizona  85281
        USA
 
        (602) 921-1113    (Sorry, I can only return calls collect.)
 
Price includes cost of media, mailing materials, and first class domestic
postage.  Overseas orders add $5 per order for Air Mail.  Time and other
jobs permitting, all disks will be mailed within 3 days of receipt of order.
 
Feel free to order more the the current number of disks available.  Excess
funds will be placed "in escrow" (refundable at any time) and drawn against
for automatic mailings of future disks as they become available.  I hope
to add at least two to four disks per month to the library.  Given that I
have a database of about 300Mb of freely distributable software to
draw upon, that should be a fairly easy goal to accomplish.
 
DISK CATALOG
------------
 
A disk based catalog is available directly from me at no charge (as long as
you supply disks and postage).  The catalog has been split into two disks
(disk 0A and disk 0B).  To get a copy send two disks and $0.65 postage to
the above address.
 
DISTRIBUTION CRITERIA
---------
 
To the best of my knowledge, materials in this library are freely
redistributable.  This means that they have met one or more of the
following conditions:
 
(1)     The materials contains explicit copyright notices permitting
        redistribution.
 
(2)     The materials were posted to a publically accessible electronic
        bulletin board and did not contain any copyright notice.
        (Such materials will be removed if it is subsequently shown
        that copyright notices were illegally removed.)
 
(3)     The materials were posted to a widely disseminated electronic
        network (such as usenet), thus implying that their author/poster
        intended them to be freely distributed.  This applies only if
        they contain no notice limiting distribution.
 
(4)     The materials contain an explicit notice placing them in the
        public domain.  This is not the same as condition (1).
 
One last note; I get frustrated when I get email from people and then
can't get a message back to them because of some sort of braindamage
in the return path.  Please don't assume that just because you never
saw a bounced message, that it actually got through to me, or even if
it did, that I ignored it.  I DO RESPOND TO ALL MY MAIL.  I don't
spend ANY time trying to figure out how to work around bad paths if
my response gets bounced back.  For best results, include your
phone number in case the email route fails completely.  Also note that
my preferred usenet address has changed recently to this machine
(fishpond!fnf), rather than mcdsun!fnf.

Subject: How to get a listing of Fish disks electronically:
 
If you can FTP, you can find the following files on SCORE.STANFORD.EDU, in
the directory <ALI.AMIGA.FISH>
 
WHEREIS           (a list of programs that've appeared on Fish disks 1..138,
                   sorted by prog name & with one line description)
1, 2, 3, ...      (detailed descriptions of what's on each disk --- these
                   are Fred Fish's own descriptions of what's on the disks)
 
You can anonymously FTP these files. Because SCORE is a TOPS-20 machine,
you can't CD to the directory, instead you need to:
 
FTP> get <ali.amiga.fish>whereis
 
If you want it let me know and I can mail you at least the WHEREIS file.

Any information starting   with  [;] is  something which   I  couldn't
verify.  Some of them were reported to me by other people, but I never
managed to  FTP  them.  Or they  seem to  be  refusing  anonymous  FTP
although they used to accept it. Some of them  does not seem  to exist
at all.  Even some directories seem to  have been purged.  The rest is
what I am using always.  Have  fun and keep  me informed about any new
sites, IP-addresses, and directories, as well  as  the ones which have
been  removed,  changed, or manipulated    (enough to make  this  list
"old"). I'd appreciate it :-)

Subject: Re: Picture swap (was Re: clite demo)
 
So I am hereby officially becoming a picture collector.  If you have
pictures, drop me a disk.  For every disk of pics I get, I'll send it
back with what I may have found by that point.
 
A few notes:
 
        1. If you send ray-traced, sending the input to the ray tracer would
                be appreciated.  That's up to you.
 
        2. If the picture can not be displayed with DPaintII or the DISPLAY
                program that comes with DBW_Render, please provide a display
                program somewhere on the disk or at least give me some clues as
                to how I should display it.
 
        3. Make *sure* you give me full mailing info and such.
 
        4. Anything you send me should be freely redistributable.  This means
                that I'd love to get digitized pictures out of your favorite
                magazine, but that's not legal.....
 
        5. If you DO violate note 4, at least tell me you did so I don't get
                into trouble with someone Official.
 
        6. Keep copies and insure yourself if you send more disks than you're
                willing to lose in the mail.
 
If I start to get some collections together, I'll do a followup and tell
people what they can do to get some pictures from me without sending
submissions.  I'm also willing to accept pictures over the phones if I
don't have to make long long-distance phone calls to do it.  If you have
DBW_Render pictures, you can just email those to me....
 
My mailing address is NOT my work address, however.  Send disks, etc to:
 
Joe Larson

Golden Valley, Minnesota 55422
 
Disks sent to me at work will get here, but home would be better....

In article <260@geocub.UUCP> anthes@geocub.UUCP (Franklin Anthes) writes:
> - is FFS a totally new FS, or just changes made to the old FS?
 
Yes and no. Yes it is a totally new file system handler, however the
way the data is stored on the disk is not changed in a really remarkable
way. The only real difference is that datablocks now have 512 bytes of
data rather than 488. [Yes, that's a "free" 5% increase in space]
 
> - What changes have been made?
 
Biggest wins come from sequentially ordered hash chains and full data
blocks. It makes long reads much more appealing (and DMA much more
efficient).
 
> - Why does FFS for diskettes have to wait until 1.4?
 
Because it won't be in ROM for 1.3, so there is this chicken and egg
problem where you have a disk and no filesystem in memory yet
that can read it, because the filesystem is on the disk you are trying to
read. See the problem ? Further, some of the stuff that diskettes rely on
(like the ability to deal with being swapped out) is not part of FFS yet.

Yes, all aspects of disk activity are faster. My wife (who uses a PC-AT
at work) commented the other day at how fast the directory popped up on
the screen. Such are the improvements. Anyway, with FFS all hard disk
activity on the Amiga are faster than equivalent activity on the Mac, PC,
or Atari.

Subject: Putting the 2000 on its side.
 
There seems to be no problem with putting the Amiga 2000 on its side to
make it fit nicely under a desk. My 2000 has been in this orientation for
approximately 10 months and I have had no problem associated with its
position. I recommend putting your computer on its left side so that the
drives are as high (and accessible) as possible.
 
You may need some extension cables for the keyboard and mouse. A
standard joystick extender cable is fine for the mouse and a standard 7
prong DIN cable will work for the keyboard. Both are available at Radio

There has been some discussion about the operation of disks and drives
in a sideways position. I have had no more or no less bad disks because
of this. However, it remains to be seen if the disks wear out faster
sideways.

ATARI VS. AMIGA: WHAT TO BUY?
 
        * the bottom line is -- whatever you like best. *
        but here are some thoughts:
 
 
WORK/SCHOOL OS features:
========================
 
        What kind of environment are you using at work/school? It is
        Likely Multi-tasking. (VAX VMS, UNIX, ?)
 
        - (AMIGA & ST) If VMS, I don't know of any VMS look-alikes for
          either machine. there is a PD editor (TVX) that can be configured
          to look like the VMS EDT editor I think... I know it can be made
          to look like VI and emacs/jove/uemacs... (unix).
 
        - (AMIGA) If unix at work,... unix editor PD look-a-likes "vi" and
          "emacs" are available. (They are also available on the ST).
 
        - (ST) If unix at work, then note that an ST version of MINIX
          has gone to Prentice Hall for distribution (out in Sept? - check
          comp.os.minix on when). You are familiar with MINIX? It is Version
          7 unix look alike muli-tasking OS, comes with compiler and
          unix-behaving tools.
 
        - (AMIGA) As you know the Amiga has multi-tasking built in, so it you
          can handle a different interface from the one at work, but are
          used to multi-tasking, you are already set.
 
        - (ST) UNIX? Today *now* there is a nice PD shell on the  ST (gulam)
          that looks a lot like the unix shell with many of the
          commands. The editor is emacs-like, and you can pause the
          editor, escape to the shell, compile a program, then bring
          the editor back to the fore ground (via "fg" a-la unix). Not
          multi-tasking. Context switching, but it is the unix look and feel.
 
        - Note: Amiga and ST can run MSDOS stuff with appropriate add-on's.
                ST cam also run MAC stuff with appropriate add-on's.
 
MIDI:
=====
 
        The ST came with midi's built in and this has generated a lot of
ST midi software.  Buy a copy of STart magazine.  There are always adds
in that artist-oriented magazine for music editors, and multiple other midi
programs.  I do not know what midi stuff is available on the AMIGA.  I
think there is a large library of midi software on the PC market.  You
may wish to look here too...
 
Final suggestions:
        1. Get several machine specific magazines on both computers.
Try to stay away from those published by the machine manufacture; they
tend to be censored and over-hyped: "See how great we are!!!!!!!!".
 
        2. Please try before you buy. - you may hate the feel of the
           keyboard.
 
*BOTH* good computers, you probably can't go wrong what ever you
choose.  To be fair, I do not own an Amiga. I own 2 Commodors (the
VIC-20 & C64) am the happy owner of 1 Atari (the ST).
 
I will not suggest either computer over the other.  That is a personal
preference.  A choice only you can make.  My experience with both
companys is about the same.  They are probably on a par with the rest of
the retail computer industry.

Ok, let me give it a try,  The 2000 comes with 512K more than the 500 but
I have seen 512K expansion for the 500 priced under $150.
You can have IBM compatibility with the 2000 but not with the 500.
The 2000 costs more $$$ but it is a little less expensive to expand.
The 2000 is bigger than the 500.
If you expand with the 500 you need alot of space.
The 500 is about $700 cheaper if you get a 1 meg 500.
The 2000 is now selling for $1499.
The 500 is now selling for $649.
 
Did I miss anything? I believe those are all the diffrences.  Hope I made
things easier rather than harder.

You'll get a speedup over no 68881 at all (assuming 1.3 math libraries).  What
you don't get is a 32 bit interface to the 68881, or a true coprocessor
interface to the 68881, so this is still considerably slower than a similarly
clocked 68020.  Given the speedups you can get with any kind of math chip,
it's probably a good idea for someone into image rendering or other heavy
duty math operations who doesn't have a 68020 type budget.

Note that for math operations, a 68020 with 68881 is several times faster than
a 68000 with 68881, even on a 16 bit bus.  The difference is of course the CPU
interface that the 68020 uses, plus the wide data bus.  The 68000 or 68020
have to fetch data for the 68881 in either case.  But while the 68000 will fetch
at 16 bits, then transfer at 16 bits, the 68020 will do it's transfers at 32
bits.  Of course, if you can only afford a fast 68000 board at $200-$300, it's
going to speed up your math more than that cash sitting in the bank waiting
for a 68020 board will...

Look on page 3 of Appendix H to the Hardware Reference manual.
Briefly, though, it says:
 
   One blink      Keyboard ROM test failed
   Two blinks     Keyboard RAM test failed
   Three blinks   Watchdog timer test failed
   Four blinks    A short exists between two row lines
                  or one of the seven special control keys.
 
It also says that you probably would not have been able to type anything
before this sequence would be completed, but if so, the key codes
would be sent to the computer and then a "terminate key stream" code
would be sent.  There is more information in that appendix.

If you bought it in the USA, it's a "B" (or someone hosed you).  The easiest
way to tell is to look at the phono jacks on the back of the machine.  The
"A" has two, the "B" has three (that extra one is a monochrome video output
that I got basically for free when using the A500 video hybrid).
 
Most stuff works in both.  What doesn't probably can't be easily added,
though with a minor modification to the case, a board swap is possible.

We kept using boxes from Germany long after switching to the US designed
motherboard.

As long as 100 pin cards are in spec, they'll work fine on both machines.  All
Genlocks should work similarly.  The B2000 video slot has many more signals,
but the only thing I know of on the market that's currently taking advantage
of that slot is MicroWay's flickerFixer, which won't work on the "A" board.

I put that feature in to allow developers who develop on the 68020 based Amiga
an easy way to test their software on a 68000.  It has the side effect of
allowing you to run software on your machine that doesn't work with the 68000.
I've found a better use for such software -- reformatting the disks it comes
on.  Really, though, there's very little software that can't be used on the
68020.
