Since where on the subject now. Is there a legal way to find out
the begin and end adresses of the ST-RAM and the same for TT_RAM
And for the ROM?
I want to write a routine that as some 32 bit number as input and
assuming that it is an address it determines if it is ROM, ST_RAM or TT_RAM
or just JUNK and if it lies in the system part of RAM or in the TPA part.
any info appreciated?

Subject: Autobooting Drive C
To: Info-Atari16@naucse.cse.nau.edu
I am borrowing my friend's Mega 2 for the summer and he has an SHS205 hard
drive attatched. When I got it, it would boot all of the stuff in the
AUTO folder on the C partition (actually, that was the only thing that
it would boot, it would not read a floppy at bootup!) I seemed to have
messed something up and now it will not boot off the hard drive, I have to
boot off a floppy and with all of the utilities, it takes forever. Does
anyone know how I can fix the C partition to autoboot again???????
Thanks,

Does anyone have a copy of the game Black Cauldron that
they wish to unload, or know where I can still purchase
a copy? I've just started re-reading the Prydain
Chronicles by Lloyd Alexander, and thought it would be
fun to play the game after reading the book.
Thanks!

According to a letter from Goldleaf, there is less than two weeks before
it is released. Seems that Goldlead is just itching to send it out ASAP
(after all, they have possibly the only FSM-ready program on the market,
thus the new GDOS is a selling point.)

Probably all channels. I would hope that they distribute it in addition

Cost? Beats me. It's supposed to include a DJ driver, as well as an HP
Laserjet driver and Epson drivers. They'd be stupid to drop any drivers
in the package.

No. They are going to charge cost plus shipping and handling when they
sell FSM.

Subject: GIF decompressor in GFA Basic 3.0 (not a viewer)
To: Info-Atari16@naucse.cse.nau.edu
REM This GFA Basic 3.0 program unpacks the images in GIF files, creating RGB
REM color tables, and an uncompressed image array. Each byte in the image
REM array points into the intensity values in the RGB color tables. This means
REM the image can contain only 256 different colors, but those colors can be
REM selected from a palette of 16.7 million.
REM
REM *THIS IS NOT A COMPLETE PROGRAM* It does not display the GIF images.
REM I leave that up to you to figure out how to do. Good luck. By the way,
REM this is pretty slow. It does run much faster if compiled.

I can't answer most of the questions, but having been in the market for
a hard drive recently, I can tell you that every dealer I've talked to
about the Megafile 30 has had the same response: "They're really slow.
Most of my customers can't deal with anything this slow."
Mind that they're dealers with non-Atari drives to sell, but it became
the expected response whenever I talked to one of them. I found a
49M 28ns drive from Carter Graphics for $414 that I'm waiting for now.
Atari's Megafile was $365 at most places that would touch them. Seemed
like a simple choice to me.

To: Info-Atari16@naucse.cse.nau.edu
Hi Lauren,
Yes, a hard drive such as the Megafile 30 can be used with a
"stock" 520ST, although I doubt there would be enough memory left to run
either WordPerfect or Publisher ST. You could however run the likes of
WordWriter and Publishing Partner. Having a hard drive connected to a 512k ST
really restricts which programs you can use; this would be an excellent time to
upgrade your computer.
Megafiles are so cheap now, because hard drive prices are at an
all-time low; and this is industry wide (not just Atari). There is nothing
wrong with the Megafile 30's; low OEM prices of the mechanism and market
competition allow the price to be low. Yes, the Megafile 30's are upgradeable;
one of the most popular replacement mechanisms for the Megafile 30 is the
Mitsubishi MR535. The MR535 (when connected to a RLL controller, like the
Megafile 30 has) is a 65m, 25ms hard drive; it simply plugs and mounts in the
same place as the Megafile 30's Seagate ST238R mechanism, although you will
need different software to format and partition the drive with (such as Supra's
Hard Drive Utilities, Diamond Cache would be nice too). I hope this helps,
take care. Bye................

There's a file at atari.archive that fixes the 2.5 meg problem... It's called
SIMMFIX.
You put it in your auto folder. It reprograms the MMU, then does a warmstart.
I get 2 bombs on the first boot attempt, but when the machine resets, it does
just fine. Any subsequent warmstarts just boot right up.
Be sure to read the instructions....
Hope this helps,

Well 2.5Mb does work on my 520STE with TOS 1.6, but it does think there
are 4Mb there. I have not had any problems yet but I have not (knowingly)
tried to use all of the memory thus far. I have the feeling that when I
do I will commit mass bit murder :-) by trying to throw them into spaces that
aren't there. I will try changing the boards round and let you know what
happens.

If you can select the "Blitter" option, do so. It is a special graphic
chip inside the machine that allows it to do Hardware Scrolling. It
makes for faster, smoother scrolling. I'm not sure about the other
capabilities. It is better than the standard, though, so use it if you
can.

Well, now I know why Bob is seen on the dialog box of the ram disk I use.
I'd thought that the programmer was really cool to spend the time drawing
Bob. Now I know that the real cool person is or was hidden inside Atari
while they were developing the machine.
For all the deficiencies of the operating system, at least it offers
slack to all who seek.

Subject: XOR (Was RE: More than 4 Meg?)
To: Info-Atari16@naucse.cse.nau.edu
I can't reply to Ralph Berg, who asked about programming for the Cazio CZ1
with XOR:
XOR is a generic patch editor that runs in Dr. T's KCS Multi-Programming
Environment (MPE). It can also be run as a standalone program. As I
understand it, XOR uses modules that describes the programming requirements
for a given synth, and then uses a generalized interface to allow that
programming. Feedback from the synth category was very favorable to XOR
over other available packages. I like the idea of going to XOR since it s
supports a lot of synths, some of which are not exactly popular models. .
If you're not familiar with Dr. T's, they write a lot of midi software that
may not always have the greatest flexibility right off the bat, but are well
supported in upgrades, and are reasonably priced. I've stayed with the KCS
through 4 upgrades now, and with Tiger and Level II, have an extremely
powerful sequencer environment that supports the functioning of many external
programs; last night I figured how to initiate other GEM programs from
within the KCS so that I don't have to reload my sequencer configuration
just to get to my all-important Daleks game...
