Message-ID: <16000010@ux1.cso.uiuc.edu>
 
        Is it impossible to piggyback 256K ram chips on the ones
        currently in my 1040 except for one address line which
        I could pull from the MMU, in order to upgrade to 2 meg?.
 
        Anyone have any ideas?

The problem is how all black is obtained.  The all black screen saver
selects 'external sync' for the video.
(An artifact of trying to work with a GENLOCK).  Since
there is no sync coming in on external, the screen goes blank.  The problem
is that the monitor expected sync pulses to keep its flyback oscillator
in time.
 
If a monitor tends to free run at a frequency too far removed from the missing
sync, the fly-back and the driver chips may overload and overheat.   Oscillators
are really strange things.
 
Also, with no sync, their is really no output signal (video information) either.
This can cause the bias on the video amplifiers to get to a point where, again,
they can overheat.
 
My old Mono, seems not to care about all of this.
My new Mono, hasn't complained (died) yet, but Atari did post a warning to
look out.
My old color, also seems not to care, but I don't run it often, or blank it
for long times.

Moshe Braner's Idle 1.2 does not blank the screen by removing signals
from the monitor. It displays a black screen using the memory below the
default video memory. If that area is in use, it just does reverse video
on the screen. It will NOT hurt your monitor. I've used it for years and
I've examined the code in detail. Moshe writes good code!

There are many programs that do what you request. I use DLII which is PD
and works fine for me. (The only version I've seen on the boards is an
Beta version but as I said it works fine.)

You'll probably not believe me but there is a thing called Atari Computer
Gmbh situated in Raunheim, West Germany. Turbo C/MAS/BUG are being sold by
Borland GmbH, West Germany. So, what should be easier than for an Atari
employee to get Turbo C via Atari West Germany? Besides, you can order
Turbo C by mail, as far as I know. All you have to live with is the
German documentation.

It probably works like this: only registered user of a software package are
entitled to updates. If you do not send in your registration card, you are
not a registered user. Ergo: you don't get an update.
 
I don't think this has ANYTHING to do with a warranty.

Subject: Mega 2 Fan Question
Message-ID: <76921@tut.cis.ohio-state.edu>
 
 I have a mega 2 with PC speed installed, and one external SF314 disk drive.
When either disk drive is accessed the fan in the mega slows down...
Is this a normal condition? Should I check my power supply? Could it have
anything to do with PC Speed?
 Thanks,
  Brian

What kind of problems are you talking about. I've been having a lot of
problems with my HD since installing Word Perfect (crosslinked files,
Duplicate directories, etc.)

I would like to add the name of M.A.S.T. (Montreal Atari ST
Users' Group) to the list of users' groups that are opposed to
software piracy.  Our library consists of PD software and
