If you have the modem on the system
after the disk drive, it could be a 
bad connector.  If the modem is on the
system before the disk drive, it could
be that the modem is not meant to
be used except on the end of a 
daisy-chain.  That's all I can think
of.
Soryy I can't be of more help.

If the power light doesn't come on,
it's the power supply, you need a new
one.  If it's something else, the
video chips could be damaged and your 
only choices would be to fix it,
junk it, or take it apart and try
to fix it (or you could take out
the parts for replacements)

Fixing it would cost more than 
replacing it.  Atari has some new ones
with vents, but they are more expen-
sive.  you should be able to find
someplace to order one from in just
about any Atari magazine.

-** Answered by DOUG WOKOUN (aa384) on Wed Sep 14 20:02:07 1988 **

I suppose you sent the first one in
before the "crash".  Well, the XF551
is a little more picky than the single-
sided alternatives.  One thing is
that is DOES read the timing hole.
The timing hole is the small black 
hole just to the right of the center
hub.  To use side 2, the disk must
have two holes.  This can't be done
by yourself as far as I know, so
you have to buy diskettes with two
holes if you wish to use the second
side.  The only brand that I know of
that has two holes is BASF.  There
are probably others.  Also, if you
are using Atari DOS 2.5 or 2.0,
you can't use both sides because
they were not built to support a
DD/DS drive.  I belive Atari is
now shipping a version of DOS with
the drives.

        Thanks for asking.

I would like to load an ATARIWRITER

I wrote. The program takes care of

a simple routine which can be used
to ENTER or SHOVE IN THERE a text
file into BASIC without a VARIABLE?

[please explain in detail, my DOS
manual is really bad]

-** Answered by DOUG WOKOUN (aa384) on Tue Sep 20 06:00:21 1988 **

Unless you're switching to another
machine, the use of a variable in 
loading text is quite necessary.
You could use machine language to
load a byte off the disk (get) and
place it on the screen (put), but
it's still the same concept.  Turbo
BASIC has a command BGET that can
be used to load a series of bytes
into a memory location and not a
variable, which could be screen
memory. 

BGET #n,addr,len

is the systax for this command.
Other than that, GET is all Atari
BASIC offers unless you use INPUT
which, of course, uses variables.

-From:ag717:qa:591069489:593661489:SX212 Modem operation

I was wondering if anyone could help me
get the SX212 Modem up on an Atari 800
(Original - 48k) with the SIO connector

I am currently using SX-Express with
the SX-Companion handler, but I am not
happy with it.

SX-Express does not have Auto-Login
capabilities or 80-Column. (I used both
of these features with my old MPP 1000c
modem with either HomePak, Amodem [Mod-
ified for Auto-Login], or VT 10^2)

If anyone either has a PD or Shareware
handler that will work with my old
term programs, new term programs that
have the features I'm looking for, or
technical information that would allow
me to construct my own handler; I
would be very appreciative.

-** Answered by DOUG WOKOUN (aa384) on Sat Sep 24 14:16:21 1988 **

Express was never intended to use 80
columns, auto-logins or any of the like.
If you can find some documents for the
handler, you could probably write your
own program using the handler.

        IS THERE A SOLUTION???

THANKS.....DAN

-** Answered by DOUG WOKOUN (aa384) on Sat Sep 24 14:20:41 1988 **

First you must make sure that your
IBM database will handle the Atari
data files.  A null modem will allow
you to transfer the files between the
computers, but you must have an
Atari 850 or a P:R: connector to
hook up the Atari to an RS-232 cable.

You could just find someone with a
modem, send them the file and have them
send it back to you using the IBM.

Also, you could upload it to a system,
but if it's something you don't
want people reading, that wouldn't be
a good idea.  

Some BBS have a file mail option and
you might be able to mail it to
yourself also.

If you know somebody with a modem,
it's easy to send it to them and have
them send it back.  The other ways
are a little more difficult.

-From:ag717:qa:591332219:593924219:SX212 Revisited!

I'm sorry that I have not made myself
clear the first time.  Let me try
again.

I understand that SX-Express (or ANY
Express program) is not designed to do
the things that I want it to do.  I
also understand that with proper doc-
umentation I could write either:
 1) A modem program that works with
      the very limited handler that I
      do have . . .
or . . .
 2) A SX-Handler that allows me to use
      the term programs that I have
      and liked with my old 300 baud
      modem.

My problem is two-fold.
 1) I have no technical documentation
      on the SX-Companion handler that
      I am useing, so I cannot get it
      to do anything other than execute
      SX-Express.  I cannot even get to
      DOS or BASIC after loading it!!!!
 2) I have no technical documentation
      on the modem so that I can write
      my own handler for it.  Typical
      to Atari, the owner's manual that
      I received barely tells me how
      to turn the modem on.

Fortunatly, I have worked with Hayes
modems, and as far as command-set goes,
the SX212 seems to be 100% compatable
(right down to the S-Registers!).

So I repeat my question!

Does anyone either have a term program
that works on the SX212 and supports
the type of options I want, or a
handler for the SX212 that allows me to
use my old programs like HomePack and
VT10^2.

A distant third would be the doc-
umentation that I have said that I
cannot get.

                Ron Boswell
                  (ag717)

P.S. If you look carefully, your pre-
     vious answer did not say ANYTHING
     that my previous question did not.
     If you cannot help me youself,
     maybe you can suggest as to who
     can?

-** Answered by DOUG WOKOUN (aa384) on Wed Sep 28 17:04:47 1988 **

Maybe I should be a little clearer
also: I don't know...

Suggestion:
-----------
If you are an ML wizard, disassemble 
the code and try to figure it out.

I don't know who wrote the handler,
but you could write them a letter and
ask them for some information.



-From:ae826:qa:591778063:594370063:XF551 Answer.

To format side two of the disk (assuming you have the disks with 2 holes)
you can use SpartaDOS 3.2d and up or MYDOS, SmartDOS, and TOPDOS, I have
only used SpartaDOS with the XF551 and it works. you don't need to flip the
disk over in that, just use the XINIT program, 40 tracks/DS  Double Density
no sector skew and you should get around 1400 free sectors of 256k each.
You need not turn the disk over since that side has been formatted when you
formatted the first side. And ADOS
has been finished fer a long time,
a few days/weeks after OSS joined ICD.
Atari is thinking of making it a commercial program in which you must buy,
BULL you say? No, that is what Atari is thinking of doing.

There should be no problem with word processors because the character
sets are store in the printer.  Programs like the Print Shop and such
will probably not support this printer.  I don't think you would have any
problems because the computer just sends ASCII code over the buses and
the printer translates it to the dot combinations.  Better to check first
with the person selling it to you, though...

-** Answered by DOUG WOKOUN (aa384) on Sat Feb 18 12:25:35 1989 **

The way I usually do it is to take
the TV switch box and use the 300 ohm
connector that normally goes to the
TV.  Since VCR's usually use 75 ohm
input, you will probably need a 
converter to hook the 300 ohm prongs
to a 75 ohm coaxial cable wire.

Then screw the 75 ohm end of the
connector into the input port of the
VCR and from the output port of the
VCR, run a cable to the television so
you can see what you are doing.

         Hope this helps-

One way that is a little
different to do this is to set up a

In order to access a record, it has
to be marked as available.  New data
would be added where the area was
marked deleted.  Sort of like how

Cursor up                       ESC [ Pn A
Cursor down                     ESC [ Pn B
Cursor right                    ESC [ Pn C
Cursor left                     ESC [ Pn D
Direct cursor addressing        ESC [ Pl ; Pc H
Alternate of above              ESC [ Pl ; Pc f
Index                           ESC D
Reverse Index                   ESC M

Clear to end of line            ESC [ K
Alternate of above              ESC [ 0 K
Clear from beginning of line    ESC [ 1 K
Clear entire line               ESC [ 2 K
Clear to end of screen          ESC [ J
Alternate of above              ESC [ 0 J
Clear from beginning of screen  ESC [ 1 J
Clear entire screen             ESC [ 2 J

Notes:
------
   ESC is Escape, ASCII 27.  Omit the spaces I have added.
   Pn is an optional decimal parameter given for the number of
positions to move the cursor, but not beyond the screen edge.  If
Pn is omitted or zero, the default of one will be performed.
   Pl is the line number.
   Pc is the column number.
   Pa is a selective parameter indicating the following
attributes.  Several may be present seperated by semicolons,
which are performed in order:
0 or None        All attributes off
1                Bold on
4                Underscore on
5                Blink on
6                Reverse video on
   Index moves the cursor down without changing columns,
scrolling up the screen if necessary.  The cursor down command is
different than this because cursor down will not move the cursor
if it is at the bottom of the screen.
   Reverse index moves the cursor up without changing columns,
and will scroll down the screen if necessary.

Examples:
---------
ESC [ 3 A           Move 3 lines up.
ESC [ D             Move 1 column left.
ESC [ 3 ; 28 H      Move to line 3, column 28.
ESC [ 0 ; 4 m       Turn all attributes off, then bold on.
ESC [ m             All attributes off.
ESC [ 1 K           Clear from the beginning of the line to the
                    cursor.

I have an Atari 800.  (Not one repair needed on it yet)  I would
like to expand the memory to 64K.  I have a 48K 800 and a extra
16K board.  I would like to know how atari stuck the extra 16K.

did they switch out the OS? or am I hopelessly lost.

-Subj: 800 MEM UPGRADE

THIS CONCERNS ONE OF THE QUESTIONS IN TECH Q & A.  I HAVE
UPGRADED AN OLD 800 TO 256K AND IT IS NOT TRIVIAL. THE OLD 800
WERE ONLY DESIGNED TO HANDLE 64K. IT REQUIRES A COMPLETE 
REWORKING OF THE OS CARD AND PART OF THE MOTHER BOARD. GOING OVER
WHAT I DID FOR 256K, I THINK THAT TO ADD ONLY 16K MORE IS SILLY.

BASICALLY THREE THINGS WILL BE NEEDED TO EVEN ATTEMPT THE 
CONVERSION:

1) THE TECH REF NOTES;
2) A SPARE OS CARD
3) ROMS TO THE 800XL/130XE(I USED THE LATER)

ALSO I CONVERTED THE STANDARD MEM CARDS FROM 16K TO 128K AND 
THEN ADDED THE REQUIRED ADDRESS DECODING LOGIC NEEDED (AGAIN, 
NOT TRIVIAL.) THIS IS RISKY IF YOU DON'T KNOW WHAT YOUR DOING ( I DON'T RECOMMEN

(THAT SAID- I DON'T RECOMMEND IT.) BUT STILL, THE MODIFIED
SYSTEM WORKS FINE. I DON'T HAVE IT ANY LONGER, BUT
MY BROTHER IS STILL USING IT AS FAR AS I KNOW.

WITH ONLY ADDING 16K (WHY?), THE COMPUTER I GUESS WOULD
BE ABLE TO USE SPARTA DOS 2.X AND HIGHER, THOUGH I'M NOT 
SURE (NEVER TRIED IT.) 

THINK IT WOULD BE CHEAPER AND LESS FRUSTRATING TO BUY 800XL
OR 130XE, BUT THEN EVERYBODY HAS THEIR OWN MOTIVES.

ANY QUESTIONS, LEAVE MAIL....

                        PCH

PS: WHEN I SAID HANDLE 64K - I'M SURE YOU KNOW THAT - I MEANT
TOTAL 64K - 48K RAM + OS AND MEMORY MAPPED CHIPS. THE PROBLEM 
BASICALLY IS THAT THE EXTRA RAM CAN BE PLUGED IN, BUT THE OS
IS FIXED - IE; CAN'T BE
DISABLED - THE XL/XE OS CAN BE ( I DIDN'T USE A FREDDIE CHIP 
(THAT WAS DUMB.)

My Atari 130XE quit working. When I turn it on (screen stays black) -
then after about 10 sec.,the screen turns blue as it should,gives
numerous flashs of white dots for a couple sec's and then turns
black again. Can anybody tell me where to start looking for this
problem?. I know the power supply is O.K - checked it on another
Atari.

-** Answered by DOUG WOKOUN (aa384) on Thu Mar  9 22:16:35 1989 **

I'm almost guessing, but I have heard
that a power surge through the modem
can damage the POKEY chip on the
main computer.

Since this chip controls most of the
interrupts in the system, it would
be impossible for the system to
"boot-up"

If you have received a power surge
that you know of or have frequent
surges (on the telephone line) due
to thunderstorms or whatnot, it could
be a fried video/audio chip.

But you'd probably be better off 
getting somebody to look at it.

for some reason I am not getting my full sound capacity out of my
monitors speaker.  If I turn it up all the way I can barely here 
the stuff.  Is it a problem with the monitor or In the computer??



-** Answered by DOUG WOKOUN (aa384) on Thu Mar 23 05:54:25 1989 **

     It might be that the sound volume
is not loud enough from the computer.

     If the sound statement is what
you are using, that could be the 
problem, but it could be the monitor
is not designed to output a lot
of sound or is just not working 
properly.  Make sure the cable to the
computer is not loose also.

     Maybe something in the speaker
cone is damaged.

-From:ah241:qa:606670711:609262711:Sound Part II

Sorry but I did not explain myself clearly before.  Here is what
it should have said:

I have an Atari 1040ST with an Atari Color monitor.  About a half a year
ago my sound level coming out of the speakers was normal, but now for some
reason I can bearly here sounds coming out of the speaker.  I have tried
Wiggling the connects but that did not help.  Is the computer not sending 
enough power through the cable or is the monitor not putting out enough 
power.



-** Answered by DOUG WOKOUN (aa384) on Fri Mar 31 20:52:00 1989 **

I know very little about the ST
and this problem is beyond me.

none of the other SysOps have
indicated that they know the solution.

If anyone has any suggestions...please

   Help!  I have an Atari 800 XL, I'm writing in Revision C Basic
(because B has a BUG, and A is less powerful).  My question is:
how could I have High Resolution Graphics on the first 1/2 of the
screen and text on the bottom half of the screen simultaneously?
   Also--where could I find the Zork Trilogy for my computer?
Thanks a lot.
                              John Rowland

-** Answered by DOUG WOKOUN (aa384) on Fri Mar 31 20:32:11 1989 **

Basic REV.A also had a bug, just like
REV.B  The Rev. B bug scrambled
programs when a multiple of 256 bytes
were inserted into a program...this
was CREATED by Atari while trying
to fix a bug in Rev.A where deleting
256 bytes from a program cause a
crash.  


To get a Display List with mixed
graphics modes...


First you need to find out where
the Display list is....

DL=PEEK(560)+PEEK(561)*256

The first three bytes at location DL
are to move the screen down...(112)

The next three bytes are a LMS
(load memory scan with the graphics
mode and screen memory location)

79 is the LMS for gr.8
and the next two bytes are the
LSB,MSB for the display memory.

for each scan line of Gr.8, use
a 15 for that byte in the display
list....then to switch to gr.0,
use another LMS (66) and the
new memory location....you cannot
have more than 4K of screen memory
without a LMS

then, put several lines of gr.0 (2)
and top it off with a jump and
wait for vertical blank

(65) followed by the address of the
start of the display list.

To map this out:


Start > 112
        112
        112
         79
        LSB (screen memory)
        MSB (screen memory)
         15
         15
         15
          ... until you get halfway
              down the screen...
              95 of these should do
              it.
         66
        LSB (screen memory for Gr.0)
        MSB (screen memory for Gr.0)
          2
          2
          2   (12 of these to get
          2... to the bottom)
         65
        LSB (START)
        MSB (START)

You can get more information from
Compute!'s Mapping the Atari which
has an excellent section on Display
List Interrupts.   There are several
DL codes for blank scan lines and
other graphics modes unavailable
with BASIC.

Try B&G for Zork and other software
.  It is about the only place left
locally.

            Thanks for asking.
