Formatting a disk means deleting the data completely. You don't have
the slightest chance of recovering them unless your friend stopped the
process soon enough.

Hello,
 
        Yesterday I was extremely excited when I read a message by
Dave Baggett speaking of the files he was plaicing in DIGISTUF.ARC and
putting on atari.archive. I ftped the file and unarced to find 3 more arc's.
None of them contained the .au converter to ST digitized sounds which is
too bad, because that was the only thing I really wanted from the archive.
Dave, if you are reading this, could you please put that file in
atari.archive, thanks.

No, It's a multi pass compiler but ANSI compatable. You have run into
ANSI function prototyping. In ANSI C the compiler checks to see if you
pass the correct values to functions in a simmilar manner to Pascal, thus
if the function is not declaired by the time you come to use it you get
errors. I allways write my programs in two file one a header file and the
other a C file. The header file in included in any file that uses the
function I have defined in the C file.
 
Example:
/* -------- FILE test.h -------- */
 
int addNumber(int,int);         /* Just tell the compiler about */
void printString(const char*);  /* The function definitions     */
 
/* -------- FILE test.c -------- */
 
#include "test.h"               /* Tells the compiler what the  */
                                /* Function defs are.           */
#include <stdio.h>
 
int addNumbers(int a, int b);
{
    return(a+b);
};
 
void printString(const char* string)
{
    printf("%s\n",string);
};
 
/* -------- FILE main.c -------- */
 
#include "test.h"               /* again tell the compiler of  */
                                /* the definitions.            */
 
void main()
{
   int a;
   a = addNumbers(10,15);
   printString("Hello I have just added some numbers");
}
 
OK, the above don't do anything except illurstrate function prototyping.
You will have to compile the two c files and then link them. For fast
development I would recomend useing a make utilitly (eg, GNU make) but
the link control files that Lattice provides work OK.
 
The other less desirable solution to your dilemer is to set the compiler
into K&R and turn off function prototypeing.

APP files are identical, and you can simply rename them. The extension .APP
is usually used if the program needs or supports GDOS (which GEMINI does).

VENUS is only the Desktop part of GEMINI - the whole MUPFEL (command line
interface) is missing.

APP files really are the same as PRG files. Normally, GEM applications are
names this way (to make sure that nobody copies them into the AUTO folder).

Simply start Gemini. It checks for the correct TOS version and tells you so,
if you still have TOS 1.00.

I have to agree with this, and I've said it before myself.  I use unlzh
1.72 by John Harris to extract on the ST, Lharc 1.20 (1.30 as of last
night) by Roger Burrows to LHarchive on the ST, and Lharc 0.03 (Beta)
by Y. Tagawa to extract and Lharchive on Unix machines.
 
I upload and download tons of stuff and I've never had a problem.  Not
once.  I believe that early incompatibility problems have been solved.
 
A few interesting things I've found about archivers in general:
 
        o If you Arc an already-compressed file, Arc will fiddle around
          for a while and then say "Storing", which is most likely the
          correct thing to do.  HOWEVER, it seems that if Arc changes its
          mind like this (from crunching to storing), the Arc file is
          * strangely large *.  My recent DigiStuff posting is an example:
          I Arc'ed the self-extracting LZH file alled DIGISTUF.TOS and
          came up with an Arc file of about 250K.  Then I forced
          "storing" by using "arc as ..." and the archive came out to
          be 215K.  Perhaps Arc is storing CRC information in the first
          case but not in the latter?  Still, it seems strange.
          BTW, this is with Arc 6.02ST.
 
        o Of all the LHArchivers, Roger Burrows' seems to make the
          smallest files.  The Unix LHA 0.03 (Beta) makes files that
          are a tiny bit bigger (no surprise I guess), and * strangely *
          the otherwise excellent Lharc 113 from Thomas Quester makes
          .LZH files that are several K larger than their Burrows LHA
          counterparts, at least in the several cases I've tried.  All
          three lharc programs can uncompress files made with each
          other, though, even though the compression factors are
          different.
 
        o The new Zoo 2.1ST at least sometimes creates smaller files
          than even Lharc.  Here are the results of a recent test I ran:
 
                mrw------- 1 u           251231 update.zoo (hi)
                mrw------- 1 u           283792 update.lzh
                mrw------- 1 u           395288 update.zoo (normal)
                mrw------- 1 u           418149 update.arc
                mrw------- 1 u          1125376 update.tar
 
          The tar file consisted of mostly C source files and DRI .o files.
          With "high compression" Zoo 2.1 achieved 78% compression.  Burrows'
          Lharc 130 was close behind, but the other schemes seem much less
          effective.  With "normal compression," however, Zoo gave its
          typically sad performance.  Given my personal experience with
          Zoo, I was actually suprised to see it do better than Arc in
          this mode.
 
          Granted, this is only one example.  But it does show that at
          least for some kinds of data, Zoo 2.1 gets compression factors
          favorable to those previously achieved only by the "dreaded"
          Lharc.
 
Just some food for thought...

Moving main() to the `top' of your program means that, unless you give
declarations for the functions used by main(), they will be assumed to return
ints.  Now, when the functions are actually encountered, and they return
something OTHER than ints, the compiler will barf.  And quite rightly so (no
matter how many passes it makes).  I also write my C programs with main() at the
`top', but I also religiously declare all the functions I'm going to use.  It's
a good habit to get into ;-)

Hi,
 
A couple of articles ago I saw something about the Lynx in this group.
Is there another group where I can find more about the Lynx, or is this
the group where Lynx-oriented articles appear?
 
Yesterday I bought a Lynx, and I am interested in the opinions on
existing games, especially the multi-player games. Before spending
money on games not worth it I'd like some feedback on what games are
worth their money. At a friend's place I saw two people play Slime World,
which is the main reason I bought the machine. Gauntlet looks promising
as well. Any other info around ???
 
Thanks!

There arn't any! Not even for the smaller developers. I've been waiting for one
for about 2 months now and I'm a registered developer!
 
At least one good thing may come of it. We may not be the beta test site of the
world like we were when the STe came out so hopfully many of the mega
STe faults
will have been fixed by the time we finally get them here.

Get a 3D, they can save the settings in NVRAM, then there is no need
to make ajustments each time you change resolutions.
from what I have read from otheres, get a 3D and you won't be
disappointed.
I don't think that the 2D will work with the ST, the frame rate of
the ST mono mode is 71.2 hz

  Can some one help me with the Supra Clock Problem,
this is the problem with the Clock Chip, Part No.
 RCA CDP6818 or Motorola MC146818 draging down the battery.
 
  I read some where that Supra was replacing faulty Clock chips.
 
  But the real problem is that this clock chip uses to
much power 50ua max, from the RCA data book.
 
  I did ring Supra to find out, but I was told that I
would have to send my Host Adapter back for them to replace
the Clock IC, with a Dallas one.
 
This was not just a plug in job, traces have to be cut, etc.
 I asked them if they could give me the details,
so I could do it myself, I told them that I was a competent
Computer Engineer, no way and could not even give me the
Dallas clock chip part No.
 
So is there some one that can give me the Part No.
of the Dallas Clock Chip, and also if Possible some of
the changes that where made to use this device.
 
If I get the Dallas Part No. I can possibly work out the modifications
for myself, but will post the information here for otheres to carry out.
 
From what I can see in the Dallas data book, they make 99.9%
compatible MC146818 that have a 10 year life with the
built in battery, Part No. DS1287 and one with a external battery
Part No. DS1285/Q with a current drain of 100 time less than
the MC146818.
 
Note: I also found out that there software version 4.01, (latest)
does not support BGM partions.
 
Thanks, Roger..

        I have read read in the STart magazine few mo
device sold in the USA which allows VCRs to be connected to an ST computer and
use it (VCR) as an backup device. Here are some parts of the article, so you
can make a better image what this device does...
 
=========================================================================
 
        DVT VCR, Fast and Affordable Videotape Backup System
        ----------------------------------------------------
 
        Thanx to Seymor/Radix, you don't have to spend hours doing the
"floppy-disk-shuffle" to backup your hard disk. With the SVT VCR backup system
you now can save all of your hard-disk data directly to video tape.
 
        The DVT package contains a 12 page instruction manual, a single sided
disk that includes the backup program and a few utilities, two five-foot RCA
cables and a cartridge module. The module plugs into the ST's cartridge port
and only needs a couple of inches of clearance from the side of the keyboard
for cables to connect. These cables plug into the Video In/Out jacks on a VCR.
 
        The DVT backup program requires at least 760K of free RAM to run. A
small portion of this is used by the program and the rest is set up as a
buffer. When you back up your hard disk, files are copied into this buffer
until it is full. This group of files, called a bundle, subsequently transfers
to the VCR. This process repeats until the backup is complete. restoration is
accomplished in similar fashion.
 
        Backups and restores can be acomplished in one of two ways: partition
or individual file. Partition san be queued so that an entire hard disk backs
up in one operation. You can backup individual files by selecting them one at
a time and then sending a bundle of file(s) to tape. A bundle of files
selected in this way can contain files from any folder and/or partition.
 
        DVT includes a verify function that checks the integrity of the tape
backupa and can identify any "audible dropuot" areas in video tape.
 
        The test which took backing up of the 7.2Mb parition from a 40Mb hard
rive took 2.4 minutes (20 seconds per megabyte). The tape lenght and the VCR
speed determine the amount of data that can be fit on a video tape. According
to Seymor/Radix, a common 120 minute VHS tape holds around 36Mb in standard
play mode, and up to 108Mb in long play mode.
 
        DVT VCR costs US $99.95, and is avaiable from:
 
        Seymor/Radix Inc.
        P.O. Box 166055
        Irving, Texas 75016
        (214) 255-7490
 
=========================================================================
 
        As tape streamers are quite expensive (and I'd rather buy another 80
megs of HD than spending $600+ on an streamer ;), I am wondering if anyone
owns/uses DVT VCR and, and if so, does he know if it is is compatible with
European VCRs? As you know, we in Europe use PAL/SECAM, and US uses NTSC.
Also, is Seymor/Radix still in business?
 
        Is there a company in Europe which produces similar device for Europian
VCR standard? (Europe? Ups, I meant Germany ;))))
 
        Thanx,
        Dalibor Lanik
 
        P.S. I'm asking all this because I managed to destroy ALL the data
on my HD (now I'm in the process of recovering) because of the faulty DMA cable
which caused damage to the DMA chip, and all FATs on my HD went to hell... NOW
I know _why_ someone would need a backup device (but still, I don't have $$$ to
spend for it) :(

I've seen things u people wouldn't believe. Attack ships on fire off the shore
of Orion. I watched C-beams... glitter in the dark, near the Tannhauser gate.
All those moments will be lost, in time... like tears... in rain. Time to die.
