Wolfgang is quite right. Actually, the header information on an .img file
contains two words that says what dpi the image is to be scaled horizontally
and vertically. If you change these values, you will resize them. I found
this out by changing the header in a picture and importing the before and
after file into Pagestream. Pagestream interpreted them as pictures of two
different sizes.

Subject: 1.44 MB DRIVE MODIFICATION (NEW FINDING
To: INFO-ATARI16@naucse.cse.nau.edu
Hello from Singapore,
I found that I could get a Sony 1.44MB disk drive
much cheaper than original 720KB Atari drive. Thus I decided to
replace my Mega4 with the new Sony 1.44MB. Reason for using
the same brand of drive is that I can swap the drive front
panel and push button with the one on Atari thus no
modification to the case is required.
I installed a Multiplexer chip (74LS157) to automatically
change clock speed from 8MHz to 16MHz only when the HD
diskette is inserted and read/write in the drive A:
I found that the neatest way to install 74LS157 chip is to
piggy-back the chip on top of one chip near to the WD1772. I
bent out all except pins 8(GND) and 16(+5V) of 74LS157 chip.
The chip underneath have only 14 pins therefore I have to
bend these 2 pins of 74LS157 chip inward to align and solder
to pins 7 and 14 of the chip underneath to tap the power and
ground as well as to hold the chip in place.
I bought 2 Sony drives for testing both drives work perfectly on IBM computer.
The 'Made in Japan' SONY can read/write and detect media change on 1040STF but
can only read and detect media change on Mega4. The drive refuse to format disk
The 'made in Malaysia SONY drive (same model No.)can read/write (format) disk
on both 1040STF and Mega4 but it will not detect media change although it does
when connected to IBM. I have to use the Malaysian SONY drive on my Mega and
correct the Media change problem by put a jumper on the drive media change
switch. All other method such as putting diode between Pins 28 and 34, jumper
between pins 2 and 34 have no effect on Malaysian made SONY. a 1.44MB Chinon
drive has the same problem as Japanese Made SONY. It could be the TOS my 1040ST
has old TOS 1.09 and my Mega has TOS 1.4. The problems that the TT and to one
can not format disk when change to 1.44MB disk drive may be due to the similar
problem that I have encountered.
As this modification is not originally means to be carried out. It's not an
Atari fault. My conclusion is that the 1.44 drive that can detect media change
correctly on Atari its circuit may conflict with Atari TOS thus make it write-
protected thus writing and formatting is not possible.
Those who posted recent message about 1.44MB conversion on the TT & other Atari
and reported that he could not format the disk may wish to try changing the
drive to a Malaysian made SONY which is a newer drive and its analog board is
different from the older Japanese made drive.
Hope this will be of some helps,
Now my request for help: Could any kind soul who has the program to set the
Seek speed/step rate for Drive A: or both A: & B: that work with TOS 1.4 kindly
post it to Atari.archive or e-mail it to me.
Many thanks in advance,

Since it's basically OS-9/68000, then you can drop by the comp.os.os9 group,
or call Microware at 515-224-1929 (US) or 0703 601990 (UK) and ask for
the "OS-9 Catalog", which gives a pretty good OS overview.

I _think_ the first models will use the 68070, later ones the 68340 (or
whatever else Motorola comes up with... they're creating new CD-I chips).
There are already two OS-9 personal computers out now which use the 68070
and part of the CD-I graphics chipset.

The clincher is that there are _two_ complete video subsystems with various

That isn't the new ST User. The completely revamped version will be

more of ST World type coverage merged in with games relegated to the

Um, there are rumors abound about an ATW adon board for the VME equiped
ST's (ie. Mega STe and TT) according to ST Format this board is basically
the transputer part of an ATW complete with its RISC based very high res
colour graphics processor and a number of T800 transputers. I believe the
board is being worked on by Atari UK and perehelion. According to ST
Format the price could be very reasonable to. So any guesses when this
STT (ST Transputer?) is likly to be available, if ever?
While talking about the ATW it is now available for 2500pounds with
educational discount. (Thats Half price!)

It's on my list of planned future enhancements for UUCODER.
I haven't tracked down BinHex source code yet. I'd appreciate
tips on where it might be found.

Most people who are likely to use such calls will probably have spotted
this anyway, but just in case:
I think the correct syntax for the first form_dial() call should be
form_dial(FMD_START,0,0,0,0,x,y,w,h);
and the closing call should be
form_dial(FMD_FINISH,0,0,0,0,x,y,w,h);
I've used these with Laser C, but I think they are standard across all
compilers. Correct me if I'm wrong.

In regard to meore memory, and what Dave Small is up to:
Yes, his board will support 12 megs I understand. I have heard that Gadgets is
currently working or several improvments. I've been using the Spectre for
years, and if I know Small & Company at all we will all be in for some nice
surprises with Spectre 3.x
Also, considering all the problems I've seen just trying to get the Mega STe to
run as a Mega STe, I would guess that the majority of the problems were in the
computer, not the Spectre...

anyone out there might have this card and be willing to give me a few pointers.
I would like to know what software works, what colors you've found that look
best, and so on. Does anyone know if there is a GIF viewer that will work on
the ISAAC card and use the 16-color high-rez mode?
Basicly any info or tips or opinions would be nice...

Subject: Noisetracker Source Needed
To: Info-Atari16@naucse.cse.nau.edu
Does anyone know if there exists such a thing as a Protracker compatible
Noisetracker (a la The Empire Noisetracker) for which source code is
available? I'm currently in the process of developing a game and it's
intended that it should have copious amounts of wonderful music. So far
I've managed to find some (possibly erroneous) documentation on the
Protracker file format and the source for a Noisetracker, which I had
intended to use as a guide from which to develop my own tracker for
embedding within my program.
However, having spent several evenings analysing and commenting the source
I've come to a couple of conclusions. 1) It doesn't work due to some
(correctable) bugs. 2) It's very obscure re the techniques used in the
arpeggiator, portamento up and down features and 3) it uses a lot of
self-modifying code, a crime punishable by death in my books.
So, does anyone know where I might find source for something more useful? I
don't intend to use it directly in my program, but with an example of a
working tracker it'd make writing my own a lot easier (esp w.r.t. the
translation between 4 voice Amiga and 3 voice ST sound).
Ta,
Al

If the graphic card manufacturer has supplied a VDI driver, then the
v_pmarker() function should do what you want. This function needs the
usual VDI setup of vswr_mode(), vs_clip(), vsm_color(), vsm_type() and
vsm_height(), and will probably not be very fast, but portability
rarely is. If you want fast, you need to get the specs for your card,
and write directly too it, or download code into it if it has a co-
processor. This of course, won't be portable, so if you're selling
a program using this, you'll have to support as many cards as you can
get info on.
Before anyone jumps in and flames Atari for this, I'd point out
that this is common to any workstation supporting multiple graphic
formats. If Atari produced their own graphic card, an optimised library
would be nice, otherwise, it's really the driver writer's responsibility
to make it go as fast as possible.

To: Info-Atari16@naucse.cse.nau.edu
The vertical bars are interference, and are quite normal.
Your monitor (fuzziness) seems to be caused by it being out of focus, I
should get your dealer to replace it, or at the very least get an engineer
to tune it up. (As I have said in an earlier article, my first one was right
out of adjustment, it looks like Atari don't adjust them on the production
line, they juat build them)
It's also well known that the monitor can play havoc with the TT floppy, this
is because Atari decided that the monitor didn't really need any shielding,
so left it off (I disagree with this as whenever I switch the TT monitor on
all FM radios in the house loose their signal! The TT on it's own hardly
produces a hiss).
You would have thought, as the Atari monitor is far more expensive than the
competition, it would be of a very high quality, but as it is it's only really
good if you get a well adjusted one.
