[continued from previous message]
BASIC desktop, a GUI written in BASIC just as a sample, what can be done
with an 8-bit computer; this one loads BASIC and text files (maybe also ML
files);
DCS, the desktop construction set from Tom Hunt; there are 3 different
versions available, a) for DOS 2.5, b) for MyDOS and c) for Sparta-DOS; I have tested the Sparta DOS version, which worked with batch files and could easily load some ML files, text files and BASIC files (which were already on the DCS disk); it also works with high densities and/or hard disk partitions up to 16MiB and supports subdirs of course; hmm, freeware or shareware ?!?
ATOS - GUI by Tom Hunt/Closer To Home.
1) Lets you use any demo or intro as a screen saver!!
2) Works with all Atari hardware, BB, MIO and Hard drives, SpartaDOS support
3) Lets you run files like full games and demos and then
return back to the desktop. It uses Overlays.

Subject: 7.5) What should I know about R: and T: modem device handlers?
The Atari computer Operating System does not provide a modem device handler. Modems can be connected to the Atari in several different physical ways: via
an 850 interface or equivalent, via a joystick/controller port, or via the SIO port. For each way a modem can be connected to the Atari, application
software code specific to that type of modem must be utilized by the computer to communicate with the modem.
Some Atari programs, especially commercial telecommunications programs, simply support one or several specific modem types, incorporating the necessary modem-specific software routines internally.
Some programs, especially earlier public domain/freeware/shareware programs, were released in several versions, each dedicated to a particular modem or modem type.
Finally, as multiple modem types gained popularity, public domain/freeware/ shareware authors started abstracting the modem device handling software routine from the rest of their telecommunication programs, allowing for a single version of the main program to work with one or more separately- distributed modem handler routines. Users were then expected to combine an application with an appropriate modem handler in order to create a complete, working telecommunications software package.
This section attempts to list all Atari modem device handler files that can be used in combination with telecommunications programs requiring such a handler.
R: modem device handler on 850 interface ROM
The 850 contains an R: handler, supporting devices R1: through R4:, in its
ROM. This R: handler supports the full range of capabilities of the RS-232-C serial interface ports provided by the 850, but is typically used with an RS- 232-C serial interface modem.
With no powered disk drive #1 present, the R: handler loads from the ROM of a powered 850 into computer RAM on system startup. An extended beep is emitted through the computer's audio signal as the handler is loaded.
The R: handler can also be loaded from 850 ROM into computer RAM as part of a system Disk Boot or afterward by running a brief software utility for that purpose. Such utilities include:
- AUTORUN.SYS, distributed with Atari DOS 2.0S (1980)
- RS232.COM, distributed with OS/A+ and DOS XL by OSS (1982-1984)
- RS232FIX.COM, distributed with DOS XL by OSS (1982-1984).
Explicitly attempts to correct some of the known bugs in the 850 R: handler. - HANDLERS.SYS, distributed with Atari DOS 3 (1983)
- RS232.ARx, distributed with SmartDOS by Rana Systems (1984)
- Should be renamed RS232.AR1 to be autorun by SmartDOS
- Supports both warm and cold re-boots of the system
- AUTORUN.SYS, as generated by the Atari DOS 2.5 SETUP.COM utility (1984)
- RS232.COM for SpartaDOS, distributed with ICD SpartaDOS and with the ICD
P:R: Connection (1986)
- RS232.SYS for Atari DOS 2, distributed with the ICD P:R: Connection (1986)
- BOOT850.COM, distributed with AMODEM 7.4 and 7.5 by Trent Dudley (1987)
- RDRIVER.SYS, distributed with Atari DOS XE (1988)
- ATARI850.AUT, distributed with MYDOS 4.50
- X850.COM, distributed with ANSITERM by Robert Sinclair (1992)
- PR.COM, distributed with ANSITERM by Robert Sinclair (1992)
- RS232.COM, part of RealDOS
- RS232.COM, part of SpartaDOS X
Special to the P:R: Connection (popular 850 workalike):
- PRC.SYS is an R: handler "translator" distributed with the P:R: Connection
by ICD (1986). Allows some telecommunications programs (such as HomePak
HomeTerm) with integrated support for 850-based modems, but that do not load
or use the internal 850 R: handler, to work with the P:R: Connection.

T: modem device handler on 1030 modem ROM
In addition to the ModemLink software program, the 1030 modem ROM also
contains the T: modem device handler that can be loaded and utilized by user programs apart from ModemLink.
The T: device handler does not use the SIO protocol for data transmission with the computer, creating potential conflict with other devices connected via
SIO that also don't use the SIO protocol, including the C: cassette handler built into the Atari OS. Consequently, there should be no program recorder attached to the system when using a T: modem device handler.
The handler supports tone dialing, but is not self-relocating, and thus must
be loaded before Atari BASIC is initialized. Extensive T: handler details published by Russ Wetmore:
http://www.atarimagazines.com/v4n4/1030modem.html
Utilities to load the T: handler from the 1030 ROM include:

------------------------------
Subject: 8.1) How may a program behave on NTSC/PAL/SECAM computer versions?
Every Atari computer unit is designed for compatibility with either the NTSC, PAL, or SECAM analog color video encoding standards. Some functional characteristics vary among these versions of the computers, so that software may behave differently depending upon whether the computer it is run on is an NTSC, PAL, or SECAM computer.
PAL B and PAL I Atari computers differ only in the TV channel frequencies used by the RF signal produced. So in terms of software compatibility, all PAL Atari computers are indistinguishable.
The FGTIA found in SECAM Atari computers is designed to be 100% software compatible with the PAL GTIA. This fact, along with the fact that SECAM computer models include a PAL ANTIC, mean that the PAL and SECAM versions of the Atari computers are completely software compatible, but with one practical exception: in GTIA Graphics Mode 1 (BASIC Graphics mode 9), while the GTIA can display 16 distinct luminances, the FGTIA can only display 8 distinct luminances.
Thus the situation essentially simplifies down to just two sets of Atari computers that may have potential software compatibility issues between them: NTSC computers vs. PAL/SECAM computers. What might happen if you run a software program designed with an NTSC Atari on a PAL or SECAM Atari, or a program designed with a PAL or SECAM Atari on an NTSC Atari? There are a number of possibilities:
1) The program may run faster or slower than intended.
In order to work with the different timings of the NTSC and PAL/SECAM video signal standards, components of the NTSC versions of the Atari computers run
at slightly different speeds than they due on PAL/SECAM Atari computers. Software timing that is based exclusively on the CPU clock rate would thus run nearly 1% faster/slower on the opposite type of Atari. This effect, while small, can be significant in applications that are computation- or timing- sensitive, such as music players, or in any programs designed to simulate real time.
The screen refresh rate of the PAL/SECAM Atari computer is considerably slower than that of the NTSC Atari. A software routine that operates as a Vertical Blank Interrupt (VBI), executed during the times between screen frame refreshes, is thus executed at considerably different frequencies on NTSC machines vs. PAL/SECAM machines. Based on this effect alone, a VBI programmed on an NTSC machine would run 16.8% slower on PAL/SECAM machines. Conversely,
a VBI programmed on a PAL/SECAM machine would run 20.2% faster on NTSC machines. (59.92Hz-49.86Hz=10.06Hz ; 10.06Hz/59.92Hz=16.8% ; 10.06Hz/49.86Hz=20.2%) These calculations ignore the above-mentioned CPU
clock rate differences, which would also come into play.
2) The program may exhibit some sort of "screen flickering" effect.
The ANTIC display list is the software program responsible for the video display, horizontal scan line by horizontal scan line. There are 262 lines available in the (non-interlaced) NTSC video signal, while there are 312 lines available in the (non-interlaced) PAL/SECAM video signal. If software written on a PAL/SECAM machine sets up an ANTIC display list that is made up of more scan lines than are available in the NTSC video standard, the program will exhibit a "screen flickering" effect if run on the NTSC Atari.
3) The system may crash.
NTSC and PAL/SECAM machines have different numbers of machine cycles available for execution of software routines designed as vertical blank interrupts (VBIs).
An Immediate VBI must complete execution within the number of machine cycles available during the vertical blank time:
NTSC: 2508 machine cycles
(262 NTSC scanlines - 240 Atari scanlines) * 114 cycles/scanline
PAL/SECAM: 8208 machine cycles
(312 PAL/SECAM scanlines - 240 Atari scanlines) * 114 cycles/scanline
8208 - 2508 = 5700
PAL/SECAM machines have a total of 5700 more machine cycles available for
Immediate VBIs than are available on NTSC machines.
A Deferred VBI must complete execution within the number of machine cycles available from one vertical blank to the next. The number of machine cycles available for a Deferred VBI depends upon the ANTIC Display List in use, but the upper limit may be derived from the total number of machine cycles per frame:
NTSC: 29859 machine cycles / frame
PAL/SECAM: 35568 machine cycles / frame
35568 - 29859 = 5709
PAL/SECAM machines could have as many as 5709 more machine cycles available
for Deferred VBIs than are available on NTSC machines.
If there are not enough machine cycles available on an NTSC machine to execute a VBI that was developed on a PAL/SECAM machine, the NTSC system will crash.
4) The colors displayed by the program are not what was intended.
When utilizing ANTIC graphics modes 2, 3, or F, NTSC Atari computers exhibit unique color artifacting effects that are not present on PAL/SECAM Atari computers. (Artifacting is discussed elsewhere in this FAQ list.) As a result, software that utilizes one of these high-resolution graphics modes can appear to be using very different colors on NTSC machines in comparison to PAL/SECAM machines.
Also, the additional color frequency generation circuitry present in PAL/SECAM machines produces a color palette that is similar to, though different from, the color palette of NTSC Atari computers. These differences are subtle
enough that they are generally not problematic.
5) The program may explicitly refuse to run on incorrect hardware.
Software may be designed to determine whether the Atari is NTSC or PAL/SECAM, and refuse to run if the hardware present does not match what is expected.
6) The program may not load correctly at all.
This would mostly likely result from copy protection techniques based upon precise hardware timing associated with disk drives, cassette recorders, or components of the computer itself, where the timing was not anticipated to
vary depending upon NTSC vs. PAL/SECAM hardware.
According to Jindroush (2/26/02), two examples of programs that run on NTSC machines but not PAL/SECAM machines as a result of timing-based copy
protection techniques (probably based on vblank timing) are Transylvania and The Quest, both by Penguin Software.
7) The program may run fine on both NTSC and PAL/SECAM machines.
Either the differences are too slight to matter, or the software may be sophisticated enough to detect NTSC vs. PAL/SECAM hardware, as described
above, and act accordingly.
An example of a program that alters its behavior depending upon detection of NTSC versus PAL/SECAM is Ghostbusters by Activision (checks the GTIA type).
=-=-=-=-=-=-=
Bottom line:
Software written for NTSC machines (North America) will (almost) always work
on PAL/SECAM machines (Europe), but software designed on PAL/SECAM machines sometimes won't work as intended on NTSC machines.
Replacing the NTSC ANTIC chip in an NTSC Atari with a PAL ANTIC changes the screen refresh rate to 50Hz, allowing most of the PAL/SECAM-only European software to run on a North American NTSC Atari. However, make sure your display device can support a 50Hz video refresh rate first!
North American Atari users might also obtain and use real European PAL or
SECAM Atari machines, with a similar caveat concerning the display device.

Subject: 8.5) What programs use a light pen or a light gun?
Contributors to this section: Bertrand M. (LEXX), Andreas Koch
While the user experiences are quite different, the Atari computer reads the horizontal and vertical positions of a light pen or a light gun in the same way. Consequently, while software programs are usually designed for either
one or the other, these two types of controllers can sometimes substitute for each other.
A light pen or light gun requires a cathode ray tube (CRT) television or monitor. Only one light pen or light gun may be used on the Atari at a time.
Also, on the 400, Controller Jacks 1-3 do not support a light pen / light gun, only controller port 4 can be used. This effectively makes many light pen / light gun programs incompatible with the 400.
Programs designed for a light gun:
Alien Blast, Richard Gore for DGS, 1993
Barnyard Blaster, James V. Zalewski for Atari, 1987
Bembel Wo by Thorsten Butschke for Foundation Two, 1998
Bug Hunt, Alan Murphy and Rob Zdybel for Atari, 1987
Cementerio, Pelusa Software, 1989
Click!, Chris Martin, 2008
Comparando Figuras, Turbo Software/M.P.M., 1989?
Crime Buster, Ron Andrzejewski & James Zalewski for Atari, 1988
Crossbow, Sculptured Software for Atari, 1988
