Hi all,
 
I've uploaded it to atari.archive.umich.edu (141.211.164.8).  For those of
you who need it mailed to you I can still do that.  Currently it is
a uuencoded zoo file approximately 300k long.  Let me know if this works
for you if you need it mailed.

Well, at least in the digest, Steve Yelvington's message and mine are one
right after another--I am the mike dorman he talked about, and I certainly
can get messages to Ian--so mail me direct at MDORMAN1@UA1VM.UA.EDU--it
won't clog up Steve's mailbox quite so much :~).
 
Mike.

   After several months of neglecting to update the list, I've made all the
changes that were in the queue all at once.  Here's a summary of what's
new and improved, and who contributed what:
 
        o Clarification made to IFF format (Jim Omura)
        o Spectrum Smooshed (*.SPS) format added (Shamus McBride)
        o Lars Michael's RGB Intermediate (*.RGB) format added (Lars Michael)
        o ComputerEyes Raw Data (*.CE?) format added (G. "Maddog" Knauss)
        o Animaster Sprite Bank (*.ASB) format added (Neil Forsyth)
        o STOS sprite (*.MBK) format added (me)
        o Cyber Paint Sequence (*.SEQ) format added (me)
 
Thanks to everyone who's contributed info in the past few months!  Also,
if I've left something out, don't hesitate to let me know.  I think I got
all the changes that were "on the stack" in there, but I may have missed
something, so don't be bashful if I've left you out.
 
As always, everyone is encouraged to replace older versions of The List
with this one.  This time around it's particularly important since so many
changes have been made.
 
Thanks all,

word    = 2 bytes
long    = 4 bytes
palette = Hardware color palette, stored as 16 words.  First word is
          color register zero (background), last word is color register
          15.  Each word has the form:
 
          Bit:  (MSB) 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00 (LSB)
                      -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
                       0  0  0  0  0 R2 R1 R0  0 G2 G1 G0  0 B2 B1 B0
 
          R2 = MSB of red intensity
          R0 = LSB of red intensity
 
          G2 = MSB of green intensity
          G0 = LSB of green intensity
 
          B2 = MSB of blue intensity
          B0 = LSB of blue intensity
 
          Intensity ranges from 0 (color not present) to 7 (highest
          intensity).
 
          Example: { red = 7, green = 3, blue = 5 } -> 0735 (hex)
 
          Caveat:  It is wise to mask off the upper four bits of each
                   palette entry, since a few programs store special
                   information there (most notably Art Studio).

Compression Scheme:
 
   PackBits compression is used (see below).  Each scan line is compressed
separately; i.e., all data for a given scan line appears before any data
for the next scan line.  The scan lines are specified from top to bottom
(i.e., 0 is first).  For each scan line, all the data for a given bit plane
appears before any data for the next higher order bit plane.  Note that this
is identical to the IFF 'BODY' image data.
   To clarify:  The first data in the file will be the data for the lowest
order bit plane of scan line zero, followed by the data for the next higher
order bit plane of scan line zero, etc., until all bit planes have been
specified for scan line zero.  The next data in the file will be the data
for the lowest order bit plane of scan line one, followed by the data for
the next higher order bit plane of scan line one, etc., until all bit planes
have been specified for all scan lines.
 
Caveats:
 
   DEGAS Elite's picture loading routine places some restrictions on
compressed DEGAS files:
 
        o Elite uses a 40-byte buffer to store data being decompressed.
 
        o Whenever a control command is encountered, bytes are stuffed
        in this buffer.
 
        o The buffer is only emptied when there are EXACTLY 40
        characters in it.
 
The important conclusion here is that
 
        No control command may cause the buffer to have more than 40
        bytes in it.  In other words, all control commands must end on
        or before the 40-byte boundary.
 
Any picture violating the last condition will cause Elite to get a bus
error when the picture is loaded.

   Several people have reported sightings of mutated Tiny pictures that
do not follow the standard format, so let's be careful out there.  What
is described here is the format that David Mumper's original
TNYSTUFF.PRG produces.

                information also follows)

1 byte          left and right color animation limits.  High 4 bits
                hold left (start) limit; low 4 bits hold right (end) limit
1 byte          direction and speed of color animation (negative value
                indicates left, positive indicates right, absolute value
                is delay in 1/60's of a second.

        x < 0   Absolute value specifies the number of unique words to
                take from the data section (from 1 to 127)
        x = 0   1 word is taken from the control section which specifies
                the number of times to repeat the next data word (from
                128 to 32767)
        x = 1   1 word is taken from the control section which specifies
                the number of unique words to be taken from the data
                section (from 128 - 32767)
        x > 1   Specifies the number of times to repeat the next word
                taken from the data section (from 2 to 127)

   The expanded data is not simply screen memory bitmap data; instead, the
data is divided into four sets of vertical columns.  (This results in
better compression.)  A column consists of one specific word taken
from each scan line, going from top to bottom.  For example, column 1
consists of word 1 on scanline 1 followed by word 1 on scanline 2, etc.,
followed by word 1 on scanline 200.
   The columns appear in the following order:
 
   1st set contains columns 1, 5,  9, 13, ..., 69, 73, 77 in order
   2nd set contains columns 2, 6, 10, 14, ..., 70, 74, 78 in order
   3rd set contains columns 3, 7, 11, 15, ..., 71, 75, 79 in order
   4th set contains columns 4, 8, 12, 16, ..., 72, 76, 80 in order
 
Note that Tiny partitions the screen this way regardless of resolution; i.e.,
these aren't bitplanes.  For example, medium resoltion only has two bitplanes,
but Tiny still divides medium resolution pictures into four parts.

-----------
51104 bytes     total
 
Note that the Spectrum 512 mode's three palette changes per scan
line allow more colors on the screen than normally possible, but a
tremendous amount of CPU time is required to maintain the image.
 
The Spectrum format specifies a palette of 48 colors for each scan line.
To decode a Spectrum picture, one must be know which of these 48 colors
are in effect for a given horizontal pixel position.
 
Given an x-coordinate (from 0 to 319) and a color index (from 0 to 15),
the following C function will return the proper index into the Spectrum
palette (from 0 to 47):

Data compression:
 
   Compression is via a modified run length encoding (RLE) scheme,
similar to DEGAS compressed and Tiny.  The data map is stored as a
sequence of records.  Each record consists of a header byte followed by
one or more data bytes.  The meaning of the header byte is as follows:
 
        For a given header byte, x:
 
           0 <= x <= 127   Use the next x + 1 bytes literally (no repetition)
        -128 <= x <=  -1   Use the next byte -x + 2 times
 
The data appears in the following order:
 
        1. Picture data, bit plane 0, scan lines 1 - 199
        2. Picture data, bit plane 1, scan lines 1 - 199
        3. Picture data, bit plane 2, scan lines 1 - 199
        4. Picture data, bit plane 3, scan lines 1 - 199
 
Decompression of data ends when 31840 data bytes have been used.
 
Color map compression:
 
   Each 16-word palette is compressed separately.  There are three
palettes for each scan line (597 total).  The color map is stored as a
sequence of records.  Each record starts with a 1-word bit vector which
specifies which of the 16 palette entries are included in the data
following the bit vector (1 = included, 0 = not included).  If a palette
entry is not included, it is assumed to be zero (black).  The least
significant bit of the bit vector refers to palette entry zero, while the
most significant bit refers to palette entry 15.  Bit 15 must be zero,
since Spectrum 512 does not use palette entry 15.  Bit 0 should also be
zero, since Spectrum 512 always makes the background color black.
   The words specifying the values for the palette entries indicated in
the bit vector follow the bit vector itself, in order (0 - 15).
 
NOTE:   Regarding Spectrum pictures, Shamus McBride reports the following:
 
        "... [The Picture Formats List] says bit 15 of the color map vector
        must be zero. I've encountered quite a few files where [bit 15] is
        set (with no associated palette entry)..."
 
 
<Spectrum 512 (Smooshed)>          *.SPS
 
   This format compresses Spectrum 512 pictures better than the standard
method.  There are at least two programs that support this format, SPSLIDEX
and ANISPEC, although the two seem to differ slightly in their interpretation
of the format.
   One point of interest: Shamus McBride deciphered this format without an ST!

Data compression:
 
   Compression is via a modified run length encoding (RLE) scheme,
similar to that used in Spectrum Compressed (*.SPC) pictures.
 
The data map is stored as a sequence of records.  Each record consists of a
header byte followed by one or more data bytes.  The meaning of the header
byte is as follows:
 
        For a given header byte, x (unsigned):
 
          0 <= x <= 127    Use the next byte x + 3 times
        128 <= x <= 255    Use the next x - 128 + 1 bytes literally
                           (no repetition)
 
There are two kinds of *.SPS files.
 
The data may appear in the same order as *.SPC files (SPSLIDEX format?):
 
        1. Picture data, bit plane 0, scan lines 1 - 199
        2. Picture data, bit plane 1, scan lines 1 - 199
        3. Picture data, bit plane 2, scan lines 1 - 199
        4. Picture data, bit plane 3, scan lines 1 - 199
 
The second variant (ANISPEC format?) encodes the data as byte wide vertical
strips:
 
        Picture data, bit plane 0, scan line   1, columns   0 -   7.
        Picture data, bit plane 0, scan line   2, columns   0 -   7.
        Picture data, bit plane 0, scan line   3, columns   0 -   7.
        . . .
        Picture data, bit plane 0, scan line 199, columns   0 -   7.
        Picture data, bit plane 0, scan line   1, columns   8 -  15.
        Picture data, bit plane 0, scan line   2, columns   8 -  15.
        . . .
        Picture data, bit plane 0, scan line 199, columns 312 - 319.
        Picture data, bit plane 1, scan line   1, columns   0 -   7.
        . . .
        Picture data, bit plane 3, scan line 198, columns 312 - 319
        Picture data, bit plane 3, scan line 199, columns 312 - 319.
 
A for loop to process that data would look like
 
        for (plane = 0; plane < 4; plane++)
            for (x = 0; x < 320; x += 8)
                for (y = 1; y < 200; y++)
                    for (x1 = 0; x1 < 8; x1++)
                        image[y, x + x1] = ...
 
Color map compression:
 
   Color map compression is similar to *.SPC color map compression, but
the map is compressed as a string of bits, rather than words.  There are
597 records (one for each palette). Each record is composed of a 14-bit
header followed by a number of 9-bit palette entries.  The 14-bit header
specifies which palette entries follow (1 = included, 0 = not included).
The most significant bit of the header refers to palette entry 1, while
the least significant bit refers to palette 14.  Palette entries 0 and 15
are forced to black (zero).  Each palette entry is encoded as "rrrgggbbb".
 
The format of the palette is described above in the section on uncompressed
Spectrum pictures (*.SPU).

   Frames are "delta-compressed," meaning that only the changes from one
frame to the next are stored.  On the ST, .SEQ files are always full-screen
low resolution animations, so the sequence resulting from expanding all the
data will be n 320 by 200 pixel low resolution screens, where n is given in
the .SEQ header.
 
   Since only the changes from frame to frame are stored, image data for a
frame will rarely be 320x200 (except for the very first frame, which will
always be a full screen).  Instead what is stored is the smallest rectangular
region on the screen that contains all the changes from the previous frame to
the current frame.  The x offset and y offset in the frame header determine
where the upper left corner of the "change box" lies, and the width and height
specify the box's size.
 
   Additionally, each "change box" is stored in one of five ways.  For each
   of these, the screen is assumed to have the full-screen image from the last
   frame on it.
 
   o uncompressed copy:  The data for this frame is uncompressed image data,
     and is simply copied onto the screen at position (x, y) specified
     in the frame header.
 
   o uncompressed eor:  The data for this frame is exclusive or'ed with the
     screen at position (x, y).
 
   o compressed copy:  The data for this frame must be decompressed (see
     below), and then copied onto the screen at position (x, y) specified
     in the frame header.
 
   o compressed eor:  The data for this frame must be decompressed (see
     below), and then exclusive or'ed with the screen RAM at position (x, y).
 
   o null frame:  The width and/or height of this frame is 0, so this
     frame is the same as the previous frame.
 
   Of the 5 methods above, the one that results in the smallest amount
   of data being stored for a particular is used for that frame.
 
Compression Scheme:
 
   Compression is similar to that employed by Tiny, but is not quite as
space-efficient.
 
Control word meanings:
 
        For a given control word, x:
 
        x < 0   Absolute value specifies the number of unique words to
                take from the data section (from 1 to 32767).
        x > 0   Specifies the number of times to repeat the next word
                taken from the data section (from 1 to 32767).
 
        Note that a control word of 0 is possible but meaningless.
 
Format of expanded data:
 
   The expanded data is not simply screen memory bitmap data; instead the four
bitplanes are separated, and the data within each bitplane is presented
vertically instead of horizontally.  (This results in better compression.)
 
   To clarify, data for a full screen would appear in the following order:
 
   bitplane 0, word 0, scanline 0
   bitplane 0, word 0, scanline 1
   ...
   bitplane 0, word 0, scanline 199
   bitplane 0, word 1, scanline 0
   bitplane 0, word 1, scanline 1
   ...
   bitplane 0, word 1, scanline 199
   ...
   bitplane 0, word 79, scanline 199
   bitplane 1, word 0, scanline 0
   ...
   bitplane 3, word 79, scanline 199
 
Note however, that the data does not usually refer to an entire screen, but
rather to the smaller "change box," whose size is given in the frame header.

? words         header length defined in 2nd word of header
 
? bytes         data
 
NOTES:  If the image is a color image (planes > 1), the planes are stored
separately starting with plane 0.  There is, however, no standard way of
storing the color palette.  Some programs may save the palette in separate
files, some may extend the header.  For this reason, you should never
assume the header is 8 words long, always get the header length from the
2nd word of the header.  Also, the line width in the 7th word is the number
of pixels in a line.  Since the data is encoded in byte-wide packets, the
actual unpacked line width is always a multiple of 8, and may be 1-7 pixels
longer than the length specified in the header.
 
For each byte x in the data section,
 
        x = 0           Pattern/scanline run.
                        Read the next byte, n (unsigned).
 
                        If n > 0 then:
                                Read a number of bytes equal to the "pattern
                                length" word in the header.  Repeat this
                                pattern n times.
 
                        If n = 0 then:
                                Scanline run.  Data for the next scanline
                                is to be used multiple times.  Read the
                                following record:
 
                                1 byte          flag byte [$FF]
                                1 byte          number of times to use
                                                next scanline data
 
                                The data for the next scanline follows,
                                compressed normally.
 
        x = 80 (hex)    Uncompressed bit string.  The next byte
                        determines the number of bytes to use
                        literally.  The literal data bytes follow.
 
        otherwise       Solid run.  The value of x determines
                        what to draw.  The high bit specifies whether
                        the pixels are set or cleared.  A 1 indicates
                        a byte-run using $FF, a 0 indicates a byte-run
                        using $00.  The low 7 bits, taken as an unsigned
                        quantity, specify the length of the run in bytes.

? bytes         data
 
   Compressed data may be either stand-alone or delta-compressed (relative
to the base picture named in the header).  Delta compression involves
storing only how the picture differs from the base picture (i.e., only
portions of the screen that have changed are stored).  This is used to
to encode animated sequences efficiently.
 
Compressed data, stand-alone:
 
For each byte x in the data section:
 
        x = escape byte         Read one more byte, n.  (n is unsigned).
 
                                If n >= 2, use the next byte n times.
                                If n = 1, keep reading bytes until a
                                byte k not equal to 1 is encountered.
                                Then read the next byte d.
                                If the number of 1 bytes encountered is o,
                                use d (256 * o + k) times.  I.e.,
 
                                if (n == 1) {
                                        o = 0;
                                        while (n == 1) {
                                                o++;
                                                n = next byte;
                                        }

                                        d = next byte;
 
                                        Use d (256 * o + k) times.
                                }
                                else {
                                        d = next byte;
                                        Use d (n) times.
                                }
 
        x != escape byte        Use x literally.
 
Compressed data, delta compressed:
 
For each byte x in the data section:
 
        x = escape byte         Read one more byte, n.  (n is unsigned).
 
                                If n >= 3, use the next byte n times.
                                If n = 1, do the same as for n = 1 in
                                stand-alone compression (above).
                                If n = 2, then set n = next byte.
                                        If n = 0, end of picture.
                                        If n >= 2, take n bytes from base
                                        picture.
                                        If n = 1, do the same as for n = 1
                                        in stand-alone compression (above),
                                        but take (256 * o + k) bytes from
                                        base picture.

                is the MSB of the byte.  (ie. a color value of 15 ($0F)
                is stored as $F0)  The bytes are stored in R,G,B order.

NOTES: Some of these chunks may not be present in every IFF file, and may
not be in this order.  You should always look for the ID bytes to find a
certain chunk.  All chunk IDs are followed by a long value that tells the
size of the chunk (note that "ILBM" is not a chunk ID).  This is the number of
bytes that FOLLOW the 4 ID bytes and size longword.  The exception to this is
the FORM chunk.  The size longword that follows the FORM ID is the size of the
remainder of the file.  The FORM chunk must always be the first chunk in an
IFF file.
 
The R,G,B ranges of AMIGA and ST are different (AMIGA 0...15, ST 0...7),
as is the maximum number of bitplanes (AMIGA: 5, ST: 4).
 
Format of body data
 
An expanded picture is simply a bitmap.  The packing method is PackBits
(see below), and is identical to MacPaint and DEGAS Elite compressed.
 
The (decompressed) body data appears in the following order:
 
        line 1 plane 0 ... line 1 plane 1 ... ... line 1 plane m
        [line 1 mask (if appropriate)]
        line 2 plane 0 ... line 2 plane 1 ... ... line 2 plane m
        [line 2 mask (if appropriate)]
        ...
        line x plane 0 ... line x plane 1 ... ... line x plane m
        [line x mask (if appropriate)]
 
The FORM chunk identifies the type of data:
 
        "ILBM" = interleaved bit map
        "8SVX" = 8-bit sample voice
        "SMUS" = simple music score
        "FTXT" = formatted text (Amiga)
 
 
<MacPaint>      *.MAC
 
1 long          version number [0=ignore header, 2=header valid]
38 * 8 bytes    8x8 brush/fill patterns.  Each byte is a pattern row,
                and the bytes map the pattern rows top to bottom.  The
                patterns are stored in the order they appear at the bottom
                of the MacPaint screen top to bottom, left to right.
204 bytes       unused
-------------
512 bytes       total for header
 
< 51200 bytes   compressed bitmap data
-------------
< 51712 bytes   total
 
NOTE:  The version number is actually a flag to MacPaint to indicate if
the brush/fill patterns are present in the file.  If the version is 0,
the default patterns are used.  Therefore you can simply save a MacPaint
file by writing a blank header (512 $00 bytes), followed by the packed
image data.
 
Bitmap compression:
 
   The bitmap data is for a 576 pixel by 720 pixel monochrome image.
The packing method is PackBits (see below).  There are 72 bytes per
scan line.  Each bit represents one pixel; 0 = white, 1 = black.
 
 
<RGB Intermediate Format>       *.RGB (low resolution only)
 
   This format was invented by Lars Michael to facilitate conversions between
standard ST picture formats and higher resolution formats like GIF and IFF.
It supports 12 bits of color resolution by keeping the red, green and blue
components in separate bit planes.
 
1 word          resolution (ignored)
16 word         palette (ignored)
16000 words     red plane (screen memory)
1 word          resolution (ignored)
16 word         palette (ignored)
16000 words     green plane (screen memory)
1 word          resolution (ignored)
16 word         palette (ignored)
16000 words     blue plane (screen memory)
------------
96102 bytes     total
 
The format was derived by concatenating three DEGAS .PI1 files together --
one for each color gun.  The RGB value for a pixel is constructed by looking
at the appropriate pixel in the red plane, green plane, and blue plane.  The
bitplanes are in standard ST low resolution screen RAM format, but where pixel
values in screen RAM refer to palette entries (0 through 15), pixel values
here correspond to absolute R, G, and B values.  The red, green, and blue
components for each pixel range from 0 to 15 (4 bits), yielding a total of
12 bits of color information per pixel.  Not coincidentally, this is exactly
the format of ST palette entries (although on ST's without the extended
palette only the lower 3 bits of each color component are used).
 
You can view a single bit plane on a standard ST by splitting the .RGB file
into its three DEGAS .PI1 components and setting the palette to successively
brighter shades of gray.
 
 
<ComputerEyes Raw Data Format>  *.CE1 (low resolution)
                                *.CE2 (medium resolution)
 
1 long          [$45594553 or "EYES"]
1 word          resolution [0 = low res, 1 = medium res]
8 words         ?
If resolution = 0 {
64000 bytes     red plane, 320 x 200, 1 pixel per byte
64000 bytes     green plane, 320 x 200, 1 pixel per byte
64000 bytes     blue plane, 320 x 200, 1 pixel per byte
------------
192022 bytes    total
}
else If resolution = 1 {
128000 words    640 x 200, 1 pixel per word
------------
256022 bytes    total
}
 
   This is almost two formats in one:
 
        Low resolution:
 
           The planes are arranged vertically, instead of horizontally.
        The first byte is the red component of pixel (0,0), the second is (0,1),
        and the third (0,2).  The 201st corresponds to (1,0), etc.  The 64001st
        byte is the green component of (0,0).
           Only the low six bits of each byte are used.
 
        Medium resolution:
 
           The picture is arranged vertically, instead of horizontally.
        The first word is pixel (0,0), the second is (0,1), and the third
        (0,2).  The 200th is (1,0) etc.
           Each word is divided up into the RGB values for the corresponding
        pixel, as follows:
 
          Bit:  (MSB) 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00 (LSB)
                      -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
                       0 B4 B3 B2 B1 B0 G4 G3 G2 G1 G0 R4 R3 R2 R1 R0
 
        Bit 15 is not used.
 
 
<PackBits Compression Algorithm>
 
The following packing algorithm originated on the Mac, was adopted by
Electronic Arts/Commodore for use in the IFF standard, and then by Tom
Hudson for use in DEGAS Elite.  The algorithm is currently used in
MacPaint, IFF, and DEGAS Elite compressed file formats.  Each scan line
is packed separately, and packing never extends beyond a scan line.
 
For a given control byte 'n':
    0 <= n <= 127   : use the next n + 1 bytes literally (no repetition).
 -127 <= n <= -1    : use the next byte -n + 1 times.
         n = -128   : no operation, not used.

If you are using the wrong version of LHarc, it IS slow. The slowes of them
all is John Webbs 0.xx. The LZH 1.13.20 is about 4 times faster than the
original 1.13, because the whole compression and decompression is entierly
written in assembler. It should be about twice as fast as LHA 1.21 in
decoding and about 3 times faster in coding.

If you have any problem with any archive and the version 1.13.20 or newer,
why not send it to me. If the archive is not damaged or if it is'nt coded
with LHA 2.xx on a PC, I will adapt my version of LHarc to read this kind
of archives.
 
If you get an error-message "Unknown method", your archive is packed with
LHA 2.xx on a PC. This is impossible to adapt to the atari st until there
are sources available,
 
If you get CRC-Errors on many files, you probably have a damaged archive.
You could then try to download it again.

Subject: Possible GCR sale...  What is the real value
To: Info-Atari16@naucse.cse.nau.edu
 
I recently posted a short message asking if $300 is too much for a GCR.
It seems that it is actually not much to charge.  However, I have to
apologize to everyone who offered to buy it, as I am still just thinking
about selling it.  If I decide to sell it, I will hold an auction later
in the summer.
 
*************************************************************************
 
Things to think about re the Spectre GCR.
 
* Mac ROMS are very expensive now.  $250+ now.  This means fewer sales
  for the Spectre which means that GBS must focus on other products to
  produce revenue.
 
* System 7.0 does not work on Spectre now.  It probably will eventually,
  knowing the way Dave Small works his magic.  But the new System will
  probably not be as compatible as 6.0.3 is for a while.
 
* On the plus side, a Spectre on a TT or SST030 is a cheap alternative
  to a Mac II.
 
* If you have a full blown mono ST system with a memory upgrade and a
  hard drive with free space, this is a cheap way to become a Mac.  If
  you need to get a hard drive or a ram upgrade kit, the price of "going
  mac" gets expensive fast (GCR needs 1 meg and a floppy, but 2 megs and
  ten megs of hard disk are closer to a usable minimum configuration.)
  The Mac Classic under the educational discount is under $1000 (I'm not
  sure how much) and it has full compatiblilty as well as giving you
  another CPU to hack on (sometimes it's very handy to have two machines).
 
* There is no SuperDrive for the GCR.  On the other hand, all disk accesses
  are faster than most macs' disk accesses.
 
# The GCR is usually very good to me.  It rarely ever crashes (under System
  6.0.5) and has let me run Microsoft Word 4.0, which seems to be a popular
  standard around campus.  I also did some programming work on it.  It
  is a useful tool.  However, it is not as disk compatible as Dave Small
  would have you believe: it failed on the two drives I was using.  One was
  a late model TEAC, the other was an NEC (which is popular with 3rd party
  disk makers for some reason).  The TEAC never worked right, the NEC was
  hacked/fixed with instructions by Small.  It is supposed to do Mac disks
  correctly with other 3rd party disk drives.

Subject: Problems using MNP5
To: info-atari16@naucse.cse.nau.edu
 
Dear Netter!
I'm quite new to computer-communications and therefore have some problems
using the MNP5-Protocoll of my new 2400 bps modem. I have found these 3
commands, which should switch the modem to auto-mnp5. They are \n3, %c1, and
\v1. But that seems not to be enough, because a few minutes after the
successfull connect my modem decides to cut the line to the remote modem off.
Working without MNP5 is fine, but sometimes disturbed by strange chracters
appearing on my Terminal (I'm using UniTerm V2.0e).
Now what AT-commands are neccesary to switch to MNP5 and how is the Terminal
(UniTerm) to configurate?
By the way Waht is the key to switch UniTerm in INSERT-MODE?
Thanks for any answer and help in advance,
Ulf

But...
 
I STILL have the following for sale:
 
Atari 1040STfm and SC1224 Color monitor.  It is 1 1/2 years old and in
PERFECT condition.  This includes a mouse, 1 meg ram, internal DS 3.5"
drive, and an RF modulator.  I've decided to throw in the following
software: Dungeon Master, Falcon, Tanglewood, Shuttle, ST-Talk,
Grid-Iron, FAS-ST, Haba-Check checking program, all with original
boxes and doc's.  I will also include a box of 10 blank disks.
Finally, I'm including 2 joysticks, (Epyx and Winner brands).
 
I paid over $1100 for all this stuff, but I'm asking only $500.
 ("Wow, what a great deal!").

If you have the wrong version of LHarc, you indeed need several versions.
Before releasing LZH1.13.20 I tested it with every version of LHarc I could
get. This includes John Webbs LHarc 0.6, several Unix versions, LHA 1.21
and Strunk. In some archives LZH 1.13.20 could not read the crc, but it
is still able to decode the archive.

I WOULD like to send my newest version to the net. But it dosen't work.
Perhaps someone can send me a instruction how to send a binary from
germany?

I got a hold of the transcript of an old Genie roundtable discussion about
the Lynx. There was some talk of an "easter egg" in Slime World - some sort
of zit-popping contest. Is there any truth to this? If so how does one
get to the "easter egg"??

  Go to the on-line instructions screen. Advance to the page where Todd
turns green. Press OPTION 1. The object of the game isto jab the A button
as fast as possible, to inflate the "zit" faster than the computer can
deflate it.
 
  This is nothing -- check out the fully-implemented version of Conway's
The Game of Life in ZARLOR MERCENARY (with cut-and-paste and a library of
lifeforms, no less).

I too have recently purchased a couple of recent issues of ST Action and
have been quite impressed with the enclosed demos- Pity we have to wait six
months for half of the things advertised therein.

        You know, I'm really shocked! I've been an Atarian for over 6 years
I've had 8-bits and ST's. I've seen the Atari vs Commodore wars come and go.
I've enjoyed reading the news in comp.sys.atari.st but lately I can't enjoy
any of it without some posting about Amiga's "superiority" from some life-long
commodore die-hards. Great! This is comp.sys.atari.st not comp.sys.amiga.*
and these little battles and irritating posts do NOT belong here. Who is in
charge of this news group anyway? Usually I read down through every article
every day, but I'm not going to if I have to sift out Amiga propaganda all
the time. If these Amiga types want to toot their own horn in there news
group fine, but they shouldn't be cluttering up ours. It seems to me that
unless you are posting something significant about the Atari ST in this
group then your message shouldn't be here. It is too bad people can get
away with this harassment in our newsgroups. Try to E-mail to these
people and you get wise comments and manure back. Get them off our news group.

WELLLLLL
 
I've used Atari computers for something like nine (9) years and I'm
REALLY tired of the Atari-Amiga wars (or is that Amiga-Atari wars:-/).
Let's be realistic here: for the time being, both machines are stagnant.
The only thing happening is the Video Toaster on the Amiga.  As far as
competing as a general use computer, both machines are beat out by
PCs and Macs.  Why can this be so, you ask.  After all, they both have
fine, overpowered and underpriced software and do whizbang things that
cost some serious bucks on PCs and Macs.  After all, both are really
COOL, Macs and PCs are for poseurs and rich-stupid people.  Why can
this be so?  The answer is compatibility.  Compatibility with the outside
world requires PC or Mac compatibility.  The strengths of these machines
lie in the amount of data you can access and the amount of work you can
exchange and disseminate.
 
OK, I've simplified.  The upper end Amigas are PC compatible.  You can
buy Mac and PC compatibility for both machines.  But to get this compat-
ibility, you must pay money.  Why bother; why not get the real thing and
be done with it.
 
If you don't hack, if you are not a hobbyist, you don't need an Amiga
or Atari.
 
 
*****
 
BTW, I will probably be using my Atari for some years to come.  It does
everything I expect of a computer, and I'm happy with that.  Once I start
expecting more that I get, I will move up to something more powerful.
