A 24-bit card with complete screen drivers for all the applications you have?
I doubt that.

You must be kidding. At least here in Germany, nobody cares when your A2000
breaks down. Especially Commodore won't care.

You have probably seen the desktop build up windows with and without a
blitter, using TOS 1.02. This means you ain't seen nothing yet.
Blitter support in TOS is not as it could be, and in general one
is tempted to say that Blitters Are Not Important. You can speed up
graphics a lot more by software.
>Amiga's blitter performs most operations about as fast as a 14 MHz 68020
>(according to Dave Haynie, a CBM hardware guy who frequents c.s.amiga.*).
The ST blitter won't stand much behind in these terms. It's just that
the Amiga OS and architecture much more relies on the fact that there
is something like a blitter and therefore uses it much more than TOS.

TOS 1.06, TOS 2.05, TOS 3.01 and TOS 3.05 support the 68010. Nevertheless,
you won't gain much from a 68010, as experiments have shown.

Sigh. We've had cooperative multitasking from the start. Applications
and accessories can send messages to each other. And I don't think the
Workbench is much of a real GUI - not before Kick 2.0, at least.

Just try to view all files in a folder with the standard workbench.
You won't get them. Instead, you have to confine yourself to a command
shell. That's not the way GUIs were meant to work.

If you look at this list closely, you'll realise that most of the
processes mentioned are equivalents of TSRs. CpuBlit is a text output
speeder (BTW, interesting to know that you're using CpuBlit while
you're claiming that your blitter is much faster than a ST blitter).
DMouse is a screen saver/mouse speeder package. Virus_Checker is also
of the TSR type. If you think about it, you'll see that the list
above was no good example for real multitasking. When working with
my ST/TT, I have at least that many processes and resident programs in
my computer.
Don't get me wrong:
I don't question the usefulness of preemptive multitasking. It's just
that you gave a bad example of your usage of this feature.

I couldn't care less if my computer has 3 or 4 digital voices. It just
doesn't matter. If you're making professional music, you can't make use
of the home-computer bleep-style digital channels the STe and Amiga
offer; instead, you will use MIDI devices (that's why the ST has a
MIDI port built-in). If you're running standard applications, you don't need
sound except the occasional beep when you've done something wrong.
For your information: The STe/TT digital sound chip has an own DMA
channel, just like the Amiga.

To my knowledge, there is no HD drive for the Amiga that handles standard
MFM disks. A real pain when shuffling data to a PC.

See above. The floppy controller and the ACSI bus have an own DMA channel.
In the TT, there is a second SCSI DMA channel.

1280x960. 72 Hz. Without a special graphic card. IMHO, a big advantage and
one of the reason why I bought a TT.

Subject: Amiga is better then what???
To: Info-Atari16@naucse.cse.nau.edu
I generally try to stay away from computer wars regardless of the platforms
involved so I'll be brief.
In article <677913506.0@therip.FidoNet> Rod.Fulk@f24.n228.z1.FidoNet.Org (Rod

There are 24bit cards for the A500 that run as low as $400 list. Granted
these don't include racy processors such as i860s or anything but they
offer good displays for a good price (you can even choose between RGB or
composite (in case you're a video professional) ).

How about some supporting for this?

Again, please support your assertions with benchmarks, etc. otherwise they're
ineffective as arguments. I'm not an Atari expert so I'd like to see some
numbers.
>Compare OS's... The St is built with a much more complete OS then ANY of the

>looked it was not available on amiga 500's yet)
From what little I've read in this newsgroup, there seem to be more than a few
people who think that TOS should be trashed (and, of course, some people who
think that TOS still has merits). I'm curious how friendly the ST's OS is
to program. Is it library-based or something else. From a programmer's POV,
the Amiga's libraries make programming even an enjoyable process :-)
>It is easy to use HD floppies on an ST.. I have yet to see on on an amiga...
I agree with you on this point. Thus far, Amiga HD floppies aren't compat.
with the 1.4 meg standard (to my knowledge).
>Comparing an ST to an Amiga at purely CPU intensive things the Amiga can not
>be compared very favorably.
How so? Again, benchmarks and the like please.
>ALL the memory can be used in an ST as compared to the amigas limitation of
>chip memory...
This only applies to applications which utilize the custom chips. This has
currently been increased to 2 MB though there are ways around the limitation.
>You must waste memory on
>an amiga to do double buffered graphics and digital sound at the same time.)
Exactly how does the Amiga waste memory doing this?

~~~~~~~~~~~~~~~~~~~~~~
Which _should_ be considered an important factor. If I offered an engineer
two systems identical systems (note that I am not implying that the
ST and Amiga are identical...) with the exception of processor speed, one
may assume that the engineer will choose the faster of the two.
>few things better in the graphics arena though.. Over all though you have no
>bussiness stating the ST is no where as good as the amiga.. It is not true..
I have made no such claim. However, I have found no facts which state that
the ST is the better of the two.
>(Multi tasking doesnt make a better machine but since most people dont realize
>they are not gonna need it they think they need it and might lewt it make some

I suppose the trend towards multitasking operating systems is bogus then?
Now I'm not going to say that "I'm running a WP, this terminal program, and
am archiving a big program while I type this" because I'm not :-) BUT, I
do have a virus checker running in the background, and I have the aformentioned
multitasking that the OS does on its own going on as I type this. Question:
when you load a program from disk, does the rest of the system come to a halt?
I don't know the ST that well but I will vouch that this doesn't happen on
the Ami.

I have a *brand new* ICD Host Adapter Plus for sale. It has been opened,
tested, and put back in the box (it's a long story). I bought it approx.
1 week ago. I'd like to recoup what I can, so I want to sell it. The list
price was $99, and ended being $106 with shipping. I'd like to get $80
for it.
It also includes all necessary cables, the ICD software (I don't know what
version, it's still in its sealed plastic bag), and a detailed manual.
Somebody make me a deal--It's the first step toward getting that hard drive
you always wanted.
Mike.

Subject: Possible GCR sale... What is the real value of a Spectre GCR
To: Info-Atari16@naucse.cse.nau.edu
Although Mac plus ROM is not as easy to find as last year, If one post a wanted
message in comp.sys.mac.wanted still possible to find a set for about $100 to
$150.(There is a set going now for bid >$90 in there) The only thing is get the
ROM first then buy the Spectre.
As system 7 goes, even a lot of Mac add on accerlator has trouble with it, one
of the Mac developer that I know has a SE with 030 board crash with system 7.
plus without 030 or PMMU, there is not much advantage to jump except probably
the true type font. And to run true type font does not require system 7, the
6.0.7 can handle true type font,only need to get the true type font init from
the ftp.apple.com located in a file call personal-laserwriter-tool.sit ( the
actural name might be silcely off, it's the new laser writer Apple introduced
eariler) and get the true type fonts from the same place in the other file call
true-type-font****.sit.hqx
Under GCR, you don't need the superdrive to import PC(or STE)files. Run the
apple file exchange from the Mac mode then insert the PC disk. The directory of
the PC disk will show up in the file exchange dialog box and ready for you to
transfer to Mac or vise versa.( Better then Mac SE).

Subject: Profile editor for Dr.T's X-oR
To: Info-Atari16@naucse.cse.nau.edu
A new version of E-oR, the profile editor for Dr.T's X-oR universal
patch editor/librarian is now available for the Atari ST.
For the uninitiated, X-oR is a program that manages all the
system exclusive messages for any MIDI capable machine (be it a
synth, effects box, MIDI mixer, switcher or whatever). The catch is,
someone has to write a "profile" for your machine. This profile
converts your machines system exclusive data into parameters that
may be used by X-oR. E-oR is a tool that allows you to do write,
modify and test profiles for X-oR. It has its own interpreted
command language (XORCL), although much of writing a profile consists of
setting up data and parameter tables.
Once a profile has been written, it may be used with any of the
four platforms for X-oR (ST, Mac, PC and Amiga). For now, E-oR
is only available for the ST.
E-oR V1.3 has an improved XORCL editor screen, with improved program
branching and tracing capabilities. A feature that non-programmers
will especially like is the new parmob editing features. This lets
you highlight any object or group of objects on the editing screen
with the mouse (sliders, text boxes, envelope boxes, etc.) and
manually move them with the cursor keys. This means that if you
don't like the screen layout on one of your existing profiles, you
can change it easily.
Various other changes and bug fixes have been made. Writing a new
profile from scratch is still no picnic, but many of the more
tedious tasks have been simplified.
E-oR can be downloaded from GEnie (if you own a registered Dr.T's
product), and can probably be gotten from Dr.T's directly by calling
their customer service line (617-455-1454). The program doesn't
cost anything if you own X-oR (and why would you want it otherwise?),
although you'll probably have to pay for the disk and postage if
you have it sent.

It sounds like a great resource! If you are able (and allowed) to provide
complete information on the mysterious GAL chips, it would be a relief. In-
structions about the VME bus is needed and an indepth review of Atari Unix
would be welcomed too.
I'll get it in whatever language available, although most of my knowledge

The person to contact at Sybex US is Diane King. She said that they are open
to suggestions, so if everyone gives her a friendly call, it could favorably
influence her decision to commission a translation.
Someone mentioned that there were software-based German-to-English translators
so maybe that method can be tried. Does anyone has experience with them?
The following is a list of all the Sybex divisions. People outside of US
might want to express their desire for the book/translated editions by calling
their nearest sales representative and request that they contact Diane King
at Sybex USA, so that she may gauge the depth of interest world-wide.

Don't get me wrong - there is nothing wrong with assembly - I use it often - but
I just don't think it is the "language-of-choice" for writing I/O programs in.
Too scary for me. I don't care if a game crashes and deletes the high-score
file. Sure, it's a bummer, but it IS `just a game'.
Then again, I guess if you can't trust a DC program, what CAN you trust! TOS?

Subject: TT Tos extensions.
To: Info-Atari16@naucse.cse.nau.edu
Are there any developers out there that would be willing to post copies
of the documentation for the exended TT ROM routines? I only ask because I am
a hobby-programmer, and if I can't have documentation for these extensions, it
might be a wee bit difficult to use them, and that would be a shame after
giving Atari my hard earned cash for this excellent but overpriced machine.
Am I right in assuming that I could otherwise only get this documentation
if I pay Atari for the privelidge of having access to such details, which would
allow me to program software that might make their machine a more attractive
prospective purchase?
Something's wrong here...

Whatever the advantages of LHArc 1.1321 might be (faster?), it does solve
the problem of those many incompatible LHarcs. Using LHarc of whatever
version could only under the following conditions be tolerated:
- There is only one LHarc version at a time.
- The source code is maintained by a single person or team.
- The source code is completely written in C (no assembly
"optimizations").
- The source code is suitable for most (better: all) machines and
operating systems.

Try spslidex.prg from atari.archive, it should work.
BTW, SPS-files are SPectrum Squeezed pics.
Have fun,

I thought it were SPectrum 512 Sequences, i.e. films like the .GL files in
the PC area. BTW is there a possibility to convert .GL to .SPS? Perhaps by
converting the single images and then re-linking them? Are there programs to
rip .GL files into .GIF and to combine .SPC or .SPU to .SPS? Which System,
Atari or MesS-DOS?

No, no sequences. Here is an extract of Dave Baggetts ST picture
formats list:
---------- CUT HERE -------------------
...
<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!
1 word 5350 (hex) ("SP")
1 word 0 (reserved for future use)
1 long length of data bit map
1 long length of color bit map
<= ? bytes compressed data bit map
<= ? bytes compressed color bit map
----------
< ? bytes total
...
---------- CUT HERE -------------------
Hope this ends the discussion,
