 Well, after a rather long vacation from the 8-bit community, I am back 
 at the Editor's job for ZMagazine.  Harold Brewer has resigned after 
 many months of excellent editing and publishing.  I want to thank Harold 
 for the assistance and wish him best of luck with future endeavors.
 After careful consideration, we are going to continue publishing 
 ZMAGAZINE for the 8-bit community.  This will be looked at again in 
 December and then a decision will be made to continue publishing.  If 
 you want to see ZMAG continue, please send us an article when you can.  
 If there is something you would like to see covered, please leave us 
 email on GEnie and CompuServe.
 Just as the rest of the community finds it difficult to support the 8-
 bit, we are getting to the same point.  There are NO new titles 
 available for the 8-bit, the support is getting down to almost nothing, 
 and public domain support just about gone.
 We are putting more effort in ZMAG till the end of the year.  We feel 
 we can make a difference and need your help!  If you are not a 
 subscriber to the pay services, send me email today and request a 
 CompuServe sign-up kit and get to the Atari8 Forum.  If you are 
 interested in GEnie leave me a message or send me a post card and I will 
 get the sign-up info to you.  The best way to get some attention is to 
 gather the community and start making noise!  With your help we can do 
 it.  If the 8-bit is dying, then let's go out with a fight!

 * As reported online by ST-Report this week, Epyx, entertainment
 software developer, is laying off some of its work force and changing
 its focus to developing video games.  This layoff will bring the
 employee count down to 16 from nearly 100.  As reported earlier this
 year, Epyx designed and developed the Atari Lynx, hand held video game
 system.  This product debuted at Comdex by Atari President Sam Tramiel.
 Epyx plans to continue developing games for the new Atari machine.
 * Last week, USA Today contained a rather large ad from Apple Computer
 displaying the Macintosh portable computer labeled the IIcx.  Apple
 officially unveiled the new computer on September 20th.
 * Where is GOE today?  ZMAG has been trying to contact Total Control 
 Systems for almost 6 months.  The last conversation we had with David 
 Sullivan was back in January.  We wonder how many people have sent money 
 for the product and also wonder if the funds have been returned.
 * The Atari Portfolio has been shipping for about a week now.  This new
 hand held computer runs on MSDOS and comes complete with 5 software 
 packages.  For the latest read Issue #38 of ST*ZMagazine.

 The following program can be used to alter any kind of text file.  I
 wrote it to convert assembly language source code files.  Each brand of
 assembler has its own set of commands and pseudo-ops.  So if I wanted to
 use an AMAC source file in a MAC/65 assembler I would have to change
 many of the commands.  This program does it all for me.  Of course I
 could have used the search and replace feature of a word processor.  But
 I don't have a word processor that will handle characters such as the
 TAB.  Also the program will insert line numbers if your assembler needs
 them.  Because the program uses INPUT to get data from files, there
 should be a carriage return within 255 bytes (six lines), otherwise a
 truncated file error may occur.
 By altering the code in lines 44 to 76, this program can be used to find
 and replace any character(s) or words.  So by replacing the definitions
 of FIND$ and REPLACE$, you can create your own customized converter
 program for any text files.  Once you have customized the program, just
 run it and follow the prompts.  If you wish to view the progress of the
 conversion without creating a new file, press RETURN at the prompt for
 destination file name, and the converted code will be printed to the
 One of the joys of Turbo BASIC is line labels; using them and named
 PROCedures means very few REM statements are needed to explain your
 code.  It also means you can renumber and add and delete lines as you
 wish.  There are no references to line numbers anywhere in the program
 so feel free to put in as many FIND$'s and REPLACE$'s as you wish.
 Also, Turbo BASIC is so fast that you can leave the program uncompacted
 and still get acceptable speed.  Take a look at PROCedure REPLACE which
 does all the work; it is short and simple because of INSTR and TRAP.
 One final note, REPLACE calls itelf!  Turbo BASIC supports recursive

 I wrote the accompanying program to edit short files.  It eliminates
 several problems that you may encounter when trying to use one of the
 many DOS' to copy from the screen editor to disk files.  In particular,
 the program allows you to edit files up to 1000 bytes long (about seven
 sectors or one GRAPHICS 0 screen).  Unlike the DOS method, it does not
 clear the screen and it allows you to edit a full 40 characters across.
 It also traps most errors.  Unlike word processors, the program allows
 you to enter any keys you wish.  I call it handy because I continually
 find more uses for it; for example, I recently realized that it is
 perfect for editing batch files for SpartaDOS, DOSXL, and TopDOS.
 For the sake of those not in possession of Mapping The Atari, I have
 commented all POKEs.  The program is uncompacted.  It may be condensed
 down to 10 lines through the use of multiple statement lines and
 substitution of screen control characters in place of the CHR$()
 function.  If you wish to condense it, you will find that all target
 lines are multiples of 10 and that all REMs may be omitted.

 Using the program is easy.  Simply give it a filename at the prompt, and
 it will print the file to the screen.  If you want to start a new file,
 just press RETURN.  You will find all your cursor controls work in the
 usual manner.  If you attempt to edit a file longer than 20 screen lines
 you will lose the first part when it scrolls off the top of the screen.
 When you press CONTROL 3, the program will save your edited screen as
 D1:TEMP.  This is meant to protect your original file.  So when you are
 finished you should rename or delete D1:TEMP as you wish.  As in BASIC,
 you must press RETURN at or before the end of a logical line (three
 screen lines).  If you don't do this, your edited screen of text etc..
 may not be saved to disk.  The program creates a white screen with black
 text.  I find this the best combination to use when I am editing
 graphics characters.

               The Breakfast Club BBS(c) Announces AUGS (c)
                       The Atari User Group Station (c)

 This document is copyright 1989 by The Breakfast Club BBS and by Gayle
 & Marty Albert.  It may be freely distributed to all so long as it is
 left essentially unchanged.  May be re-formatted as needed.
 The Breakfast Club BBS (TBC) is pleased to announce the opening of the
 AUGS Network.
 The Atari User Group Station is THE place for ALL Atari User Groups to
 get the information that they need to better serve their members.  This
 includes all of the "online" magazines, individual articles on a wide
 range of topics, files for club disks, industry information, and much
 All of this information is presented in an easy to find manner and is
 provided FREE to all Atari User Groups!!  (except, of course, the cost
 of your phone call!  TBC and AUGS are PC Pursuit-able to help reduce the
 cost of your calls)  All you need do is call and get the information
 that you need.
 All registered Atari User Groups are allowed one account with UG access
 level.  This means that, as an official User Group, you will have up to
 90 minutes per call with NO total daily time limit and UNLIMITED access
 to download files!  That's right!  No upload:download ratio, unlimited
 time, and all for FREE!!
 Individuals may use the AUGS area, but there is a 60 minute per day time
 limit and an upload:download ratio of 1:7.
 The AUGS Network is a special area within TBC BBS with its own message
 bases (8 of them), E-Mail area, and File Bench so there is no need for
 you to wade through all the "routine" BBS activities to get what you
 need.  This will save you and your User Group $$$ in phone bills!
 AUGS supports ALL Atari computers from the "old reliable" 400 to the
 state of the art ST/Mega and the soon to arrive TT, STACY, and beyond.
 As the machines arrive and the need crops up, AUGS will be there with
 the latest information for you and your User Group.
 The main service that AUGS provides is to supply Atari User Groups with
 an easy and fast way to get articles for their newsletters.  If other
 services should be needed in the future, AUGS will add them in a timely
 and useful manner.
 AUGS calls several of the "online services" every day, is in close
 contact with Atari Corp. and a number of third party developers for both
 Atari 8-bits and STs, and makes frequent checks of other sources of
 information so that the information provided is up to date, concise, and
 above all, accurate.  This frees your User Group newsletter editor from
 the hassles, time expense, and monitary expense of having to call all
 over to get the needed information.  One source, one call.
 AUGS will even handle "special requests" for information for you!  Just
 drop the AUGS SysOps a note with the details of what it is that you need
 and we will be happy to make a complete search for it and get back to
 you.  Sort of an "online encyclopedia" for User Groups!

 In response to the requests of several users, here is some information
 that will allow you to install a write protect on your ST412/506 hard
 drive.  This is a very easy feature to install, so much so I am still
 not quite sure why it isn't standard equipment!  First, locate pins 6
 and 12 of the 34 conductor ribbon cable that is connected to your hard
 drive.  Pin 6 is the Write Gate line, and Pin 12 is the Write Fault
 signal.  The Write Fault line normally only goes low when a write
 operation has failed.  By tieing the two of them together, the computer
 will think the hard drive is incapable of completing the write
 operation, and will prevent data from being written.  Install a DPDT
 switch in a convenient location where it can easily be fixed.

                       to 6      from 6  jumper
                         |       |       | 
                         |       |       |
                      to 12      from 12 jumper

                      (bottom view of switch)

 Split these 2 wires in the 34 conductor ribbon cable, and install a
 switch following the above diagram.  You find write operations normal in
 one switch position, and the normal "You cannot modify the disk in drive
 x: because it is physically write-protected.  Before you retry, remove
 write protection." dialogue box.
 Should I Replace It?
 There are several factors one needs to keep in mind in order to arrive
 at the best solution to this question.  These are:

 1.  The size or storage capacity of the failed drive.  It no longer
     makes good economic sense to repair a 5 or 10 meg drive.  These can
     be replaced by a larger mechanism than the one currently in use, and
     often at a substantially reduced price.
 2.  The amount of use or "mileage" on the failed drive.  Most hard drive
     mechanisms have a rated life of between 30,000 to 50,000 hours.  A
     normal hard drive, used in home or in the shop, gets approximately
     1,500 hours of use per year (if the drive was part of a file server
     or bulletin board that was up 24 hours a day, then this shoots up to
     approximately 8,760 hours per year).  So, if your mechanism is 2
     years old, you have only used approximately 15% of its normal rated
     lifetime, and therefore would be a reliable drive for a reasonable
     period of time after its repair.
 3.  Many manufacturers have an excellent reputation, while others are
     known for their flaky products.  If you have a Seagate, Miniscribe
     or Maxtor drive, you can have it repaired and you know you'll still
     have a top notch drive.  Now on the other hand, if the drive is an
     MMI or Tulin unit then pitch it, you'll be glad to got rid of the
     potential headache!
 4.  Cost of repair versus cost of replacement of failed drive.  A widely
     used rule of thumb in this are is that repair of a drive only makes
     good sense if the price is less than 2/3 the cost of replacing the
