Subject: 1.44 Meg on ST...
To: Info-Atari16@naucse.cse.nau.edu
 
This is related to the "bad floppy" message I posted..
 
Since I have a new 1.44M floppy mech, I was wondering were I can find
info on how to get it to work..  I seem to recall there was a modification
that had something to do with routing a faster clock to the floppy controller..
If it a different floppy controller chip is needed that is ok (if you read my
other message it looks like it is bad and will have to be replaced anyways).
Of course I will need a program to format 1.4M disks as well.. or at least
some specs on how to right my own..  And one last thing.. how about
compatibility problems (GCR?)....  thanks... yonder@netcom.com

Apparently, its not that easy. I hooked it up like this, and got nothing.
Is it possible to get a composite signal on older ST's with out having to
buy a video key? My motherboard is rev. D. Has anybody attempted this?

From what I know about the SH204 , it has a standard SCSI host adapter,
so this would not be a problem.
You will have to setup the Windcap file, that is part of HDX 3.02,
this file is used for the Formating of drives.
The info is in the Windcap file, just enter your details of your drive.
Note, this is just a simple Text file..

Help! How can I connect a Zenith Data Systems ZVM-135 RGB Monitor to an
Atari 1040STE? Here's the ZVM-135's connector pinout:

This monitor is switchable from RGB to Composite. It has an DB-25 RGB
connector and a set of RCA phono type jacks for composite. There was
a message floating around (dated 4 Jan 87) that showed how to connect
a Sony XBR monitor to an ST and it works (I've seen the result). I
realize that I could just use the composite input with the STE but I
would like to use the RGB for obvious reasons. Anybody got any clues????

Well from what I read these Graphics cards use the Mega Buss, this is
not in a ST or STE...so could be a problem..

Subject: Floppy drive trouble
To: Info-Atari16@naucse.cse.nau.edu
 
Recently my internal DS drive in my 1040STf stopped working correctly..
I managed to waste several disks before I realized it was going, uhg..
 
I thought for sure it was the drive mech that had gone bad, so I got another
one (actually a TEAC model, that a friend of mine had successfully used to
upgrade his SS drive).  Anyways, it still wouldn't work..  My hard-drive
still works fine though..  So currently my bet is on the floppy controller
chip (WD1772) or possible the buffer chip (U8 a 7406)..  Anybody else
out there think diffrently?  I cannot get a drive to read or write or format.
It will attempt to do all three but always fail miserably!  My computer fails
with three diffrenent mechs: my TEAC, my old Atari drive, or my friends
external TEAC-modified drive..  My friends (520ST) will work with any of the
drives..  (He swapped my old Atari mech. into his old SS drive case)..
 
Another realted deal:  my floppy light on my 1040 has always flashed very
faintly while my hard-drive is on..  I seem to recall reading about his
before..  Is this good, bad, or just annoying?  Is a fix available?
 
Well, any advice would be greatly appreciated, but it looks like solder sucker
time to me... :-(

What is exchanger, and how did you get a 1.44 in your Atari..  (As should
be obvious from my recent posts I am interested in this and I decided to
reply on the NET cuz I figure others might want to know as well)..  I will
own a GCR soon (I hope) and want to know how a 1.44 will work.. thanks

++   I'm having trouble getting files to uncompress properly that have the

Uncompressing .Z files requires using '-d' as an option to 'compress', e.g.
 
compress -d sndfile.Z

The reason this did not work is that the AES uses a basepage that comes before
the one used by the desktop (in TOS 2.0/3.0). You'll have to use the element
"p_parent" to find the parent process' basepage:
_BASPAG->p_parent->p_parent->p_env. If this doesn't work, try one more level.

Of course, you could always get NeoDesk, since it replaces shel_find and
avoids this whole mess in the first place <smile>.

Short of changing your color settings in your NEODESKH.INF file, you can
always use a drawing program to invert the colors. For instance, if you
have Degas Elite you can use the "Remap" feature to change white to black
and vice-versa.

1. You need a news/mail feed. Start by making your college system
administrator your friend. If that doesn't work, look in comp.mail.maps
for your state's UUCP maps and try contacting sites named therein. If
you still come up dry, contact postmaster@psi.com and/or uunet@uunet.uu.net
and be prepared to pay for service.
 
2. You need software.
 
> Please provide locations of software also if possible.
 
atari.archive.umich.edu (PD/Shareware), Beckemeyer Development Tools
(commercial). The Michigan archive should have at least two or three
versions of UUCP. Beckemeyer's UUCP is fairly cheap and will multitask
under Micro RTX/MT C Shell.
 
> Can this be done

Yes. See Rodney's Mercury UUCP modules, STadel BBS, UUPC (not
recommended), Mailtruk (written in GFA BASIC), etc. I know of two or three
others that are in operation but not released (including the s/w run here
at thelake).
 
I'm also beta-testing a new UUCP package from the author of a BBS system;
details will surely be made public at a later date.
 
> How do you register your address? With whom do

To get your site registered in the UUCP Zone maps, contact your region's
map coordinator. If you do not know your region's map coordinator, contact
the UUCP Project at one of the following addresses:
 
        domain-request@uunet.uu.net
        
 
If you cannot send electronic mail, telephone
        +1 703 764 9789
 
UUCP sites can obtain Internet-style, fully qualified domain addresses.
The preferred method for freestanding, small sites in the United States is
to register with the US domain. For details, contact westine@isi.edu or
get information by sending mail to service@nic.ddn.mil with a Subject:

     I called GDT Softworks this week and was told that the NX1000 printer

If so, where did you get your driver?

I have also had this problem for quite some time. The first STe I got had
the DMA problem (note: I use an SH205 drive), so I quickly returned it to Atari
Norway. Three weeks later I got a new STe, with exactly the same problem. Some
time later I returned this also to Atari Norway, for replacement. This time
they tried, unsuccessfully, to repair the damage. So I gave up and learned to
live with the failure.
 
Recently I spoke with a guy at Atari, who told me that they now had got the new
DMA chips. The older ones had a massive internal bug, causing it to overheat
and malfunction. Atari Norway now has accepted the bug and offers an upgrade
to everybody who has got an STE with a flakey DMA chip, free of cost.
 
I'd suggest that you have a chat with the guys you bought the STe with, or if
they won't help you, open your STe and stick some cooler ribbons to your DMA
chips to prevent overheating. That at least should get rid of your problems.

I read in some German ST mag that a new task switcher for the ST was planned.
The difference from earlier task switcher was to be that instead of simply
switching tasks in the memory, this one would save the active partition to
disk and reloading the wanted task from disk, allowing you to use the full
memory of your ST. Sounds like a good idea to me... And I guess TT compati-
bility goes without saying. ;-)
 
I'll see if I can find the mag for more accurate info.

It's already on atari.archive.

Using the /AS to generate the BERR?? What a great hack!!! Even motorola don't
mention that it can be done that simple - instead they say (quote) :
        "BUS ERROR AND HALT OPERATION
         ...
         External circitry must be used to determine
         the durtion between address strobe and data
         transfer acknowledge before issuing a bus
         error signal..."
 
/AS and /DTACK is coupled very closely... (great hack)
 
There is one thing that worries me though - 1uS timeout??? From what
I can see in the motorla docs. then a Read-Modify-Write Cycle have
the /AS low for 8.5 cycles (at 8Mhz this is sligthly longer than 1uS??)
Don't you mean something like 64 cycles (or 8uS???).
One thing is sure - the read-modify-write instruction TAS, don't trigger
a bus-error (it's used to check if the blitter is ready).

Kind of WOM (write only memory), it's very cheep to manufacture - there is
one problem though (it's kind of hard to get the information back out) ;-)
 
Even better than generating a /DTACK on internal ROM, is generating it
on the ROM port - remember to put the R/W signal through a hole in the box...
 
Keep up the good work, TRH - and let us know all the details...
