  Why on earth would you run a word processor or shell in 24bits? EVen if
the Amiga had 24bit graphics built in I wouldn't run my Workbench on it
because it would slow down ALL screen rendering to  a sluggish
halt without a something like a 34010 onboard. Instead, I'd have
the Word processor and GUI set to 8 or 16 colors (3d look) and the paint
program on another screen set to 24bit. All the current Amiga graphic
cards work with the OS because they are still using the custom chips
for their tricks. HAM-E and DCTV work with all paint programs and all
displayer programs. (even things like AmigaVision authorware)

  In the US FedEx will come to your house, pick up your computer, and
repair it quickly. For A3000's someone comes to your house (onsite
repair). What other countries do is different since each Commodore
sub-company has different policies. Does Atari even exist in the US?

  A blitter helps out alot if you only have a 68000/20.

  Yes, it's better integrated on the Amiga, and shared nicely as is
alll resources on the Amiga.

  And the ST doesn't gain much from running at a _slightly_ faster
processor speed.

 Intuition is the GUI, workbench is the file/finder system (e.g. like
Finder on the Mac). I never used workbench before 2.0, but I haven't seen
many Atari users who used GEM either. GEM doesn't look too hot on that
lo-res screen.

  You do in 2.0. There are _numerous_ workbench replacements/enhancements
out there. But 2.0 beats the pants off all of them. (2.0 kicks the
stuffings out of GEM too)

  That's because the poster probably has an A3000 with a 68030. CPUBlit
ONLY gives a speed increase on the maximum resolution screens and only
for things like text rendering. It would slow down massively trying to do what
the blitter does (like combine 3 DMA channels of data using one of the
256 logic operations, plus masking ans shifting, and filling the pattern.)
The key phrase here is "parallel processing". Letting the blitter
do something takes the load off the CPU.

  But TSR's don't share the CPU, one of them runs until it completes
it processing and then the next one does. The more of them you have
running in an interupt/os patch routine the more sluggish  the computer
will get. You should never hog interupts. TSR's on the Amiga under 2.0
are done using commodities.exchange which allows you to set up handlers in
the input.device that watch for certain hot-keys/events. While they are
waiting, they are taking ZERO cpu time.
  How about what I am doing now? Right now I have a terminal loaded,
in the background I have lharc unarcing some gif pictures I downloaded
earlier which are passing the output names to a script which runs them through
GIF->IFF. Meanwhile, I have 2 shells open and one of them is running
a corewars simulator which is battling two programs (mice vs mortar).
In addition to this, I am getting no visible slow down on my terminal
which is running at 19,200 baud on a USR HST.

   Amiga channels don't bleep. They have 4 DMA channels to themselves,
8 bit sound, 4khz to 28khz. You can change the sampling rate on demand
and can attach DMA channel to have one channel module the volume and
frequency of the other (allows you to get synthesis effects)

  Except when you run things like Amigavision or hypertext/authorware
applications where you want to combine animations with digitized sound.
For CDTV it's a nice addition, along with it's 16bit sound and it's MIDI
port.

  But does it have DMA for each channel? Can you change the DMA rate?
I heard the STe's DMA sound is fixed at one frequency/sampling rate and
can't change it.

 The new HD drive on the A3000 has 3 modes. 880k, 1.44mb, and 1.76mb.
1.44mb mode was the main reason for making it. You can also buy
$200 SCSI floppy drives.

   The A3000 has 32-bit for it's harddrive , and it normally gets
xfer rates of up to 2mb/second (and this only eats 5% of the CPU time
while doing it.) The Amiga has over 25 DMA channels. The A3000 now has
8 integrated custom chips to handle them.

(A2024)  1024x1024 PAL on the Amiga without a graphic card, just need a nice
monitor. (The 1024x1024 also has 4 grey colors for the 3d GUI look)
With Commodore's A2410 you get up to 1024x1024 with 256 colors out of
16.7 million.

I was alluding to the fact that there is no real gfx standard for
the Amiga right now. Much like the situation in the PC world. I think
having a general scheme for implementing graphic card drivers is a
definitive plus for an OS - the ST's VDI allows just this.

Admittedly, this is good service. No doubt about that. I'm
impressed.

I didn't claim that. But remember that it's not only the 10% clock
difference that makes CPU-intensive jobs on the Amiga slower. You must
take the video hardware into account which costs additional cycles.

Who uses lo-res? Gamesters - but not me.

The new workbench is clearly better. But we were discussing the former
version and the philosophy behind it.

I know, I've read the CpuBlit docs.

Right you are. I didn't like the fact that the original poster
overemphasized the importance of a blitter in general. I don't
question that it's useful - but it's not what makes or breaks a
computer.

Likewise, I didn't say multitasking is a no-no. I would like to have
it here (besides: I can have it on my machine, though not officially
by Atari). The original poster just gave a bad example for its usage.

I know all this. I've read the hardware manuals. The new STe/TT
sound hardware is similar in may respects - but it still bleeps,
just like the Amiga does. At least when you're talking about
professional music!

It's _nice_ to have it, I agree upon that. But I don't need it. That's
why I bought the ST and the TT instead of an Amiga.
 
>  But does it have DMA for each channel? Can you change the DMA rate?

That's wrong. I didn't delve into the details yet, but I'm sure there
is more than just one sampling rate.

Does it format standard MFM format so that every PC can read it?

We know all that. What do you want to prove by that?

From what I've heard, the 2024 is a monitor with special hardware
integrated in it that buffers screen frames and displays them at
quadruple the speed the Amiga sends it. This way, the Amiga sends
a forth of the whole screen in every screen frame, and the monitor
composes the complete picture. This means you have a real refresh rate
of 50Hz/4 or 60Hz/4. Not exactly what I would call "without a
graphic card".

Well, the bad news is, the information you request is probably covered by a
non-disclosure agreement.
The good news is that ++jrb's bindings for GNU C have support for all the new
functions.
If you get those, you should be able to tell how to call any particular
functions (and the names are reasonably self-explanitory, and similar to the
ST bindings they resemble), and you could probably get away with requestion
specific information here--like stuff about just what Mxalloc does, things
like that.

Much more address range is "wasted" by the generous hardware register
assignments. No, I don't think this is a serious restriction. At least,
I don't know a single application that would run on a 1 MB ST without
GEM and doesn't because GEM installs its own data areas. It wouldn't be
bad to reclaim the space GEM allocated for itself, but I think there are
lots of other, more important things in TOS that should be improved
before this.

The difference is: DOS machines won't understand 1024-byte-sectors.
And file system compatibility has always been of some importance
for Atari, as it seems.

Not yet - as far as I know. I don't know what the author did with it.

Even TOS 3.01 seems to have timing loops. When moving TOS 3.01 to TT-RAM,
thus speeding it up by 20 to 40 percent, sometimes you get problems
when reading and writing HD disks ("data corrupted" alerts and the like).
I think this is due to some tight timing loops that break in the fast
part of RAM.

Most of the memory GEM uses is malloc()'ed just like any other memory block.

Add to Rainer's list:
 
- The source code and executable code should be Public Domain (ie. no calls
  for Shareware fees involved)
 
One of the reasons I despise most of the LHarc versions is that their authors
are trying to make a buck while they introduce incompatibilities.  (The author
of xlharc 1.2 excluded from this list...)
