630.0. "Looking for BLITZ PD package" by BACHUS::PIRLET () Wed Oct 11 1989 11:43

    In the st*zmagazine #39, in the article Public domain shelf, 
    There is a thing called BLITZ. There follow an extract of the
    magazine.

 BLITZ
 ~~~~~
 If you are a capable person where hardware mods are concerned, you might
 want to look into BLITZ, which contains the necessary documentation and
 code to allow you to build a cable (cost: $22.00) which functions as a
 software copier.   This is accomplished by sending the data from one
 drive to the printer port, thence to a second drive.  We did not test
 out this project ourselves, but thought it was worth noting here.  If
 you try this project and succeed, we would hope you would use this
 inexpensive copier for your own personal back-ups, and NOT for piracy
 purposes.

    Has anybody seen this public domain package, and would it be possible
    to copy it from somewhere.

    	Thanks in advance.

630.1Be careful about BLITZ!UKCSSE::KEANEThu Oct 12 1989 06:1022
    Hi,
    
    There is something very "funny" ie peculiar, going on here. In the UK,
    Power computing are marketing a Blitx copier, consisting of a lead, and
    software to drive it. You have to provide your own second disk!!. They
    are asking 25 pounds or abouts for it. SO they DEFINATELY dont think
    its in the PUBLIC DOMAIN.
    
    The whole market for mechanical copiers, Blitz, happy cart, Romantic
    Robot, etc are in disarray, due to the new Copyright legislation that 
    came into force in August. Most of the firms quit selling, but Power 
    Computing are still advertising.
    
    The story I heard is that the Blitz will copy one particular type of
    protected disk that a firm DJL, (who sell the protection software and
    technique, to the disk publisher), have employed on the disk.  DJL are
    now changing their copy medthod to defeat the Blitz. They have said
    that they are waiting to see if Poweer change the Blitz software. If
    Power do, then DJL will prosecute them under the new Act, as the change
    to Blitz could only be to overcome DJL's programme, and would be a
    direct breach of the new copying law!!
    
630.2BREW11::LANEFri Oct 13 1989 09:0513
    I know someone with a circuit diagram and some software for something
    that sounds identical to this Blitz gizmo. He also gave gave me
    a different story to its origin. He said that an engineer from
    Birmingham University (England) who had an ST was fed up with the
    slow backup process and the difficulties of backing up protected
    software for his own use, and invented this copier, and released
    it into the public domain. Several shops (including Software Express
    in Birmingham) are now selling it and there is nothing that he can
    do.
    
    I will check with him to see if it is "Public Domain" and if so
    I will post a note on how to make one and upload the software.
     
630.3BLITZ info from ARC fileMDCRAB::MCLENDONFri Nov 10 1989 16:45150
    Here's the text of the original file included in the ARC set as
    included with a package sold by a mailorder company in Ohio.
    I've reformatted it slightly.  Tell me where to upload the ARC
    file, and I'll send it.  Or, send email and followup with a disk
    to me @DCO/216, Landover, MD 20785.  Sorry, not enough local
    storage to guarantee long-term availability on-line.
   
    ===============================================================
                                THE HAPPY KILLER
                                  BLITZ COPIER

    Are  you  ready for a  $22.00 copier that will copy as good,  or
    in  most cases better,  than a $150.00  cart?  Yes??  Well then, 
    Blitz is for  you.   Blitz is a revolutionary new back-up system 
    for the Atari  ST computer.   Using  a  special  cable (that you
    can  make  yourself) and software included in this arc,  it will 
    back up your software at a  speed and power unheard of before.

    If  you know a little about wiring and how to solder, that's the
    most that this copier will cost you. If you have to have someone
    make one up for you,  it might cost you $30-40 (although some
    people have been known to pay up to $50 for a pre-made cable).

    That's  right,  all  that  is needed is a cable (and two drives).
    No internal  wiring to be done in the  computer.   No  special,  
    over-priced cartridges.  In a nutshell,  all  you  do is cut an 
    Atari drive cable in two and then attach a third plug that goes 
    into your printer port.  What this cable does, is copy from drive 
    one, out through the printer port to drive 2. (Copying is ALWAYS 
    from drive 1 to drive 2.)

    It reads from  drive 1  and writes to  drive 2  at the same time!
    So in the time it takes ACopy,  ProCopy,  or Happy to just read 
    a disk into memory, this program has read AND written out the same 
    disk in one pass.   And it does not care if the disk is protected
    or not,  it copies just  as  fast either way  (this  way  you can
    make a legal backup copy of all your protected software). Plus, it
    seems to copy a lot that ACopy, ProCopy AND Happy won't copy!!!

    BLITZ operates the disk drives at a very low level. When backing 
    up disks it  should go through an entire disk without a pause.  
    If it  does  pause (for   more  than  a  second  or  so)  then  
    it may have got out of synchronization.  In this case,  press 
    ESCAPE to abort the copy and start it going again.   So the best 
    thing to do is watch it copy and count down the tracks.   If it 
    stops for even a second,  then you can forget it and start again,
    as it has gotten out of sync and the copy will not work. But for
    a program as fast and as cheap as this,  you can afford to  take 
    the time to count down the tracks.

    One other thing.  There are very few programs that this program
    won't copy  IF you're drives are in alignment and up to proper 
    speed.   If  the copy  that  you make does not work properly,  
    try  changing  your  drives around (if possible) or try it on 
    someone else's computer and drives.

    BLITZ comes as a program or a desk accessory.  To run it as a 
    program you will need "BLITZ.PRG" and "BLITZ.RSC" in your 
    working folder.   To run it as  an accessory,  you will need 
    "BLITZ.ACC" and "BLITZ.RSC" on the  root directory of your 
    boot-up disk.

    If  you  are  unsure  as to whether a disk is single-sided or  
    double-sided copy it double sided (the main difference will be 
    that  it  will  take longer).

    BLITZ will quite happily appear to write to a write protected  
    disk.  Do not  worry here - If a disk is write protected then 
    there is NO WAY  that BLITZ can write to it (unless your disk
    drive is  faulty).  However,  you must be careful that when 
    you DO want to write to a disk that the disk is not write 
    protected - because BLITZ will not notice.

    IMPORTANT  NOTE:  You  will not be able to use your external 
    drive in a normal way with the BLITZ lead plugged in.



                           MAKING YOUR OWN BLITZ CABLE

                 (See BLITZ.PC3 or BLITZ.IMG for cable layout!)

    
    
    Here's all you'll need........

    1 Atari drive cable.           Cost = ~$20 for a six foot one.
    1 24-pin printer plug (male).  Cost = $1.00
    1 Printer plug hood.           Cost = $1.00

    ....That's it!  Just print out the BLITZ.PC3 or BLITZ.IMG file 
    and you'll see how to hook up the printer plug into the drive cables.

    I suggest that you obtain an Atari drive cable and cut into two 
    parts to obtain plugs one and two.

    Plug 3 is a 25-pin male D connector, available from Radio Shack.

    On machines with one internal drive and one external drive,  
    plug P1 into the computer drive-out port.   Plug P2 into the 2nd 
    drive's drive-in port and plug P3 into the computer printer port.

    On machines with two external drives,  connect drive one in the  
    normal manner.  Plug P1 into the drive 1's drive-out port.   
    Plug P2 into drive 2's drive-in port and P3 into the printer port.

    You might consider which setup you have before you cut the cable.

    With this setup, the computer will not recognize drive 2 unless 
    the BLITZ software is running.   So if you leave your machine 
    setup with the BLITZ cables connected,  you will lose the use 
    of drive 2 for everything but copying.

    Switch boxes can be setup to allow you to leave the setup intact.

    I'm  sorry  but I can't tell you the color code on the  Atari  
    cables as every one is different.

630.4Not quite everything...MDCRAB::MCLENDONWed Nov 15 1989 01:1310
    Yes, there *ARE* some games that BLITZ will *not* backup, so I asked a
    friend of mine why this is.  Gee, if you copy the WHOLE TRACK, what
    else is there to check?  His answer was this:  Timing.  Yes, some
    software authors apparantly use the timing of sectors between tracks.
    That is, positioning the head on sector 1, track 6 and then timing how
    long it takes to go to sector 1, track 9.  It *could* be that BLITZ
    does indeed copy the whole track, but doesn't synchronize each track
    from the original disk.  Just a thought...

re .4

	There's also the "flaky bits" protection scheme.  The
	programmer uses special equipment to write bits that are
	between a zero and a one.  The idea is that they will not
	reliably read one or the other.  The program reads these
	bits several times.  If they are identical every time, it
	must be a copy.  I don't know if anybody is actually using
	this, but if they are, it would be impossible to copy
	without special equipment.

                        BLITZ - THE BACK UP SYSTEM
                        ==========================
 
        ******** YOU MUST HAVE 2 DRIVES TO USE THE BLITZ !! ********
 
BLITZ is a revolutionary new back-up system for the Atari ST computer.
BLITZ uses ONLY a special cable and software to back-up your software at
at a speed and power unheard of before.  There is NO internal wiring done
to the computer.  The BLITZ cable copies from Drive 1 out through the
Computer printer port to drive 2.  It reads Drive 1 and writes Drive 2 at
the same time.  The time it takes a normal copy program to read a disk,
the BLITZ reads and writes the disk in one pass.  The BLITZ backs-up
protected and non-protected disks in the same amount of time.
 
BLITZ - CONNECTIONS (Using BLITZ cable purchased from AT YOUR SERVICE)
======================================================================
 
BLITZ ONLY copies FROM Drive 1 (an internal drive or an external drive)
TO Drive 2 (an external drive).
 
1) If Drive 1 is external, connect the Computer to Drive 1 in the normal
   manner using your original ST drive cable.
 
2) The rectangular 25 pin DB connector connects to the Computer's printer
   out port.
 
3) If Drive 1 is internal, the circular 14 pin DIN connector with the
   thinner cable connects to Computer drive's out port.
 
   If Drive 1 is external, the circular 14 pin DIN connector with the
   thinner cable connects to Drive 1's out port.
 
4) The circular 14 pin DIN connector with the thicker cable connects
   to Drive 2's in port.
 
BLITZ - INSTRUCTIONS
====================
 
You will NOT be able to use your external drive in a normal way with
the BLITZ cable plugged in.
 
BLITZ comes as a program or a desk accessory.
 
 - To run it as a program, you will need "BLITZ.PRG" and "BLITZ.RSC" in
   your working folder.
 
 - To run it as an accessory, you will need "BLITZ.ACC" and "BLITZ.RSC"
   on the root directory of your boot-up disk.
 
If you are unsure as to whether a disk is single-sided or double-sided,
copy it double sided.  (Copying double-sided just takes longer).
 
BLITZ will quite happily appear to write to a write protected disk.
DON'T WORRY! - If a disk is write protected then there is NO WAY that
BLITZ can write to it - unless your disk drive is faulty!
 
BLITZ operates the disk drives at a very low level.  When backing up
disks it should go through an entire disk without a pause.  If it does
pause (for a second or more) then it has gone out of synchronization
and you MUST recopy the disk.  In this case, press ESCAPE to abort the
copy and restart it again.
 
 
BLITZ - CONSTRUCTION
====================
 
Before constructing the BLITZ cable, you should have some knowledge about 
wiring and soldering, a good pencil-type soldering gun, and about $25.00
worth of parts.
 
If you do not want to attempt to assemble the cable, you can purchase a 
built cable for $35.00 (which includes the built cable, software and
shipping) from:

                           TOTAL  $25.00 (PREPAID ONLY)
 
To assemble the BLITZ cable, basically all you have to do is cut an
Atari disk drive cable and add a third plug that goes to your computer
printer port.  If you own an internal drive you should measure the
distance from your computer to your external drive and cut the cable
accordingly (Remembering that the total cable length is 6 feet and that
the rest of the cable goes from the computer's printer port to the
computer's disk drive port).  However, if you own two external disk
drives, cutting the cable in half is probably better, because both
drives should be of equal distance from the computer.
 
On the next page are all the connections necessary to build the cable.
However, the cable wire colors are ONLY from the cable supplied by
AT YOUR SERVICE.
