A reasonable speculation, IMHO. And as long as we're talking about a
1993 time frame, it would also be fair to bring even the 68050 into the
discussion.

Promising 80 MIPS by Feb. 1992 for $40 in (large volumes, I assume)?
Sounds great, but it is just that -- a promise. Has intel ever made
good on the promise that its i860 would run at 50MHz so that the 150
max MIPS figure hyped by the press could come to light? How fast
does the chip run under normal conditions (i.e. with interrupt
processing ON, using usual compiler output, using affordable (read
slower) chips for memory)? Anyone want to take bets on whether
intel's benchmarks had interrupts enabled, or ran the dhrystone
benchmark from 80nsec memory?

At least with a 68040, with its familiar instruction set, we know
what kind of performance to expect by simply looking at the average
number of instructions per cycle and the capacity of the cache.

Other questions to be resolved: how efficiently would the processor
emulate a 68000; is the microcode well geared to emulate its rich set
of addressing modes and (small) irregularities? Would it have enough
micromemory to do it? Can it address enough registers, or would it
have to draft part of the cache for this role, inevitably slowing
things down? How fast can it do a multiply or divide (it would have
to do this very quickly in general purpose microcode to beat out an
040 with a built-in FPU with dedicated microcode)? We wouldn't know
all of this until the machine and emulation software were implemented.
That's a long way off.

Also, a lot of fast cpus will be introduced in this year of 1991, so
that 80 MIPS (whatever that means in real terms of performance) may
not seem as fast by comparison in one year. And 1993? Well, in
computer years, that's ages hence. By then, the 68050 may be a more
familiar sight. It is difficult to speculate on numbers relating
its performance with the information we have now, but...there was a
recent announcement that Moto just built the largest, most dense chip
yet (for the US Navy, too advanced for mortals like us to buy, with a
good amount of space devoted just to nuclear-proofing redundancy),
and one must begin to wonder what they're going to be able to do with
their commercial products (that don't need to waste any space for
redundancy) by 1993.

I'm all for power without price as much as the next guy, but my general
feeling is that it's too soon to tell. As long as one can speculate
all the way out to 1993, one can speculate about a lot of other things,
many of them silly...like the Common Market banning American chips
because the high frequencies might disrupt brain processes that
control the ability of consumers to choose for themselves between
labels stating "with hormones" or "without", or the Japanese opening
their market to American rice due to a widespread boycott of Japanese
submarine propellers :-P. When I see the TT040, or the PgC-ST at my
dealer...or even at Toys-R-Us...I'll be convinced. Until then we can
only make suggestions to Atari and hope that they'll listen. Right
now we are having enough trouble getting them to put a 1.44 Meg drive
into the TT...(by the way, TRH, your portable design is fine the way
it is, IMHO).

Subject: Cooling fan easy and it works!
To: Info-Atari16@naucse.cse.nau.edu

I just installed a Radio Shack muffin fan (part # 273-243B) on my hot
ST and I can report that it works like a charm. I left the machine on
all night and it's still blowing cool air.

Installation was easy. I went for functional instead of pretty, so the
fan is on top of the ST rather than inside. My ST would flake out after
a couple of hours and the spot on top of the ST over the power supply
would feel extremely hot. If I shut it down for 10 mins, it would work
fine. I drilled two holes in the top of the ST over the power supply
to screw the fan to the case. I drilled a third hole to run the wires
through the top of the case. Then, I cut and soldered these wires:


-----red wire ------ / -------- red wire ---

---------black wire --- disk drive
fan power
connector
------ blue wire --- / -------- black wire ---

-------- black wire ---


The ST has stayed cool all night and I'll bet this even makes her last
longer. Highly recommended for Z-ram owners. This cost me about $15;
you can probably find a 3in 12V DC fan cheaper at a real electronics
store, but they're hard to find around here so Radio Shack had to do.

There is a good graphics card for 1040 from Matrix GmbH...
If I remember correctly 800x600 with 256 colors on a 14"/16" multisync.

I currently have one of these towers, and I am quite satisfied, altough
there is a Mega 4 inside, not a 520 or 1040. There is well enough
room for my two seagates, laser controller and two floppies with HD-interface.
And they are cooled down with 3 thermo-controlled fans.
I am just looking forward to fit a Delta Modul in...

Exchanger -> Apple File Exchanger, a program with you can move files from
MS-DOS (and ST) floppies to Mac. Requires Mac with super drive or a
Spectre GCR 3.0 with Atari ST.

I have a German HD-adapter on top of the WD-1772 02-02 floppy-controller
chip. A small circuit board, that controls the clock-rate for the drive
and some other things. Formatting and controlling software are included.

This HD-drive does odd things in Spectre. It is not very reliable to use.
If a floppy is reported bad in HD-drive, it still works in DD.
(luckily I have two drives...) But it works great with Apple File Exchanger.
Even 1.44Mb MS-DOS floppies are usable. But you can not use 1.44Mb Mac-
floppies with it (at least format, I haven't tried reading already formatted
one). The problem is the step-rate of the drive. If I could find a program
that could adjust steprate in Spectre, it would be very nice.

I have the HD-drive mainly for larger storage-capacity in ST-mode and
for compatibility in AT-emulation.

Subject: Graphics on the STE - v. generally speaking...
To: Info-Atari16@naucse.cse.nau.edu

It seemed reasonable to point out here that VGA uses a minimum of (I hope I
have this right) 256 K of screen memory. I'm rather nearer to certain that
most super VGA uses a Meg. This isn't the sort of thing that would have been
considered reasonable when the ST was designed.

Making the display system independent (ala PC) has the advantage of allowing
you to make improvements when technology changes. It has the disadvantage
of causing proliferation of semi-compatible 'standards'. (Look at the
distribution kit of any high-end PC application. There are many screen
drivers.)

The SM124 is *true monochrome*, it supports no gray scaling whatsoever.
A pixel in a hi-res ST picture is either black or white there is no
in between. To some degree this is a feature. Combined with the 70Hz
refresh rate and 640x400 resolution the SM124 provides and incredibly
solid display for doing serious work.

It would be surprising if, say a 320x200 256 color GIF pic, was even
recognizable on it, though. There simply are not enough pixels there to
dither it properly.

I have seen mono GIF viewers that get around this by displaying in a
window which can be scrolled, thus allowing better dithering. You might
want to look around for such a viewer.

> Am I doing something wrong?

Not really... but a color display is much much better for viewing GIF pics,
even mono GIF pics (see below).

> 2) Does the STE have gray scales, you know, proper shades of gray, not

Yes, 16 in 320x200 mode
4 in 640x200
1 in 640x400

> How can I use these scales?

View the picture on a color monitor.

> 4) Is it possible to get Gif images to look remotely nice on a STE?

Someone else answered your question 'no'. IMHO, this is complete BS.
Below is how I typically view GIF pics, usually 320x200 256color images.
Many times you can view these with no loss in resolution or clarity:

1. Get GIF pic.
2. Convert to Spectrum 512 format using GIFSPC (<-- available at an
archive near you)
3. View the Spectrum pic. (<-- viewers also available at archives)

Since you're new to the ST series, I'll tell you what Spectrum 512
format is in case you haven't heard of it:

Spectrum 512 picture format uses some software trickery to display more
than the maximum 16 colors in 320x200 color mode. It changes the color
palette on a per scan line basis with a maximum of three changes per
line thus, you can have up to 48 different colors per scan line.

This allows creation of pictures which display the entire 512 color
palette of the ST on screen simultaneously. I don't know if the extended
4096 colors of the STe are supported but you still shouldn't have any
problems using 512 colors.

If you try to to view incredibly hi-res pics (ie. 1024x1024 at 16Million
colors) they still won't look all that great. GIFSPC can scale the
resolution down, however... I have some 640x400 many color pics which
look very nice on my ST when converted to Spectrum.

Well in fact there seem to be three (two on the ST?) active shell levels above
the current program while you are in the auto folder. If I set those they are
not propagated to the GEM desktop (TOS 1.4 or 3.01), which has two levels
of it's own. In fact the environment for the two desktop levels is changed
to contain only PATH=\0. When I change the desktop p_env's gulam
notices the changed external environment, but shel_find (and thus
rsc_load) stil doesn't.

Am I still doing something wrong?

I reread the readme file that goes with environ.prg. In this readme
it is stated that source should be included. But I didn't find it in the
archive (from some local BBS I think), does someone have this source.
I also would like to know who the author is.

Personally I prefer command line shells for most things. But it might
be a good idea to replace shel_find.

you say?".. All of the floppy controller IC's that JDR had are almost
exclusively under $10 and the 1771 is $5.. Almost all of these IC's are
40 pin and I am sure more sophisticated than the 1772 (though I may be wrong,
but why can't I run a 1.44M)? Anyways, I call up B&C and San Jose Computer,
and sure they have it but it $25 (!!) at either shop.. So, my question is: is
this the price I must pay, or is there an alternative? Hopefully, there is,
but obviously I'll pay $25 if I have too.. I even went to the extent to call
Western Digital (the IC manufacturer), they gave me the number of a local
distributor, who informed me that it had be "obsoleted".. bummer..
Well, anybody got any advice (another Atari dealer with lower prices maybe?)

Subject: WHAT KIND OF FILE HAS A "SPS" EXTENSION?
To: N <info-atari16@naucse.cse.nau.edu>

I have a number of pictures that have a "SPS" extension, they
are suppose to be spectrum pictures. However, spectrum pictures
have "SPC" compressed, or "SPU" uncompressed. What program
reads SPS files? Many thanks
