AspeQt is a cross-platform, free and open source Atari 8-bit serial
peripheral emulator.
AspeQt emulates various Atari 8-bit peripherals like disk drives and
printers via a SIO2PC cable. If you are familiar with software like
SIO2PC, APE, Atari810, AtariSlO, AspeQt, etc., you probably won’t have
any problems getting used to AspeQt.
AspeQt currently runs under Windows, Linux and Mac OS X. Other Unix-like
operating systems shouldn’t require too much effort. The absolute
minimums aren’t easy to tell but a modern Linux distribution with Qt 5
libraries.
In order to do anything useful with AspeQt, you will need an Atari
8-bit computer and a SIO2PC cable. SIO2PC cable is an interface that
connects the Atari’s serial bus to the PC’s serial port. Since many
newer PCs lack a real serial port, you may need a UART card, or a high
quality Serial-to-USB adapter (FTDI chip based devices were tested
successfully, others may not work as intended) or a SIO2PC USB
interface (instead of serial), If you opt for the latter however,
please note that the “AtariMax SIO2PC Universal Interface USB Edition”
is not officially supported as it uses proprietary USB device drivers.
You don’t need any real Atari disk drives or printers to use AspeQt.

In order to be able to use AspeQt, you need to configure it to suit your
hardware. When it’s running for the first time, a dialog will pop up
asking you if you wish to open the configuration dialog. Click “Yes” to
open the Options dialog. You can also access this dialog from the
Tools/Options menu item.
On Linux, you have to choose a serial I/O backend first. If you have
installed the AtanSlO package and you have a RS-232 port, the
recommended way is to use the AtariSlO backend. If you have a USB
adapter or you don’t want to use AtariSIO for any other reason, choose
the standard serial port backend. This is also the only available
backend on Windows.
First, enter a port name. On Windows, it should be something like COM1,
COM2 etc. Check the device manager to see which one of them is
installed. On Linux, it should be /dev/ttyS0, /dev/ttyS1 etc. for RS-232
ports or /dev/ttyUSB0, /dev/ttyUSB1 etc. for USB adapters.
Next, you will have to select a handshaking method. The handshaking
method tells AspeQt which one of the RS-232 pins is connected to Atari’s
command line. There are 3 supported methods: RI, DSR, CTS and NONE.
Check your SIO2PC interface’s documentation to learn which one of them
is used for your cable. Note that NONE (no handshaking) is highly
experimental and not recommended for day-to-day use, in this mode AspeQt
will ignore Atari's command line (SIO7) and will monitor the COM port's
RXD (Atari SIO5) line instead. No handshaking mode was included to
experiment with wireless (bluetooth) serial interfaces.
The “High speed mode baud rate” combo box selects the transfer speed to
be used for the high speed mode. Some OS /DOS for the Atari supports
higher transfer speeds than the standard 19200 bits per second. Not all
DOS /OS are capable of using 3x speed and some treat 2x as a special
case for XF551 drives, so you may need some experimentation to find the
best setting. 1x option is provided for unreliable connections, like
when using a cheap USB adapter or when running AspeQt under
virtualization software and/or on a slow CPU computer.
If your serial port supports arbitrary bit rates, you may check the “Use
non-standard” speeds check box and select a POKEY divisor to be used in
high speed mode, the lower the divisor, the higher the speed. Usually
real COM ports and some VCP (Virtual COM Ports) don't support
arbitrary baud rates, FTDI chip based serial-to-USB cables do support
arbitrary baud rates, and are thus the recommended type of cable for use
with AspeQt.
The exact formula for the nominal speed is:
baudRate = clock/ (2*(divisor+7))
Where dock is \~1,773,447 for PAL, and \~1,789,772 for NTSC, however,
it’s not always possible to reach nominal speeds. So, 1x is divisor 40,
2x is divisor 16 and 3x is divisor 8. Divisor 0 is \~126kbits/second
and that means approximately 6x.
Please note that very few OS/DOS will be able to function with such high
speeds. Currently the only tested software that can reach divisor 0 with
AspeQt is the hisio OS
patch. As a final warning,
some Atari 8-bit computers have capacitors connected to their SIO lines
that can interfere with high speed transfers. In short, speeds beyond 3x
are not guaranteed to work in every case.
The Complete/Error delay field selects the delay which is inserted after
the Acknowledge response to a command by AspeQt, before AspeQt then
sends the Complete response, or an Error response (whichever is
appropriate). If you experience SIO errors or retries, increasing the
value here should make the transfers more relible. Decreasing the value
may slightly increase performance, but at the risk that you cause
errors. There has to be a minimum delay from the last bit of the Ack to
the first bit of Complete or Error, or the Atari might not recognize it.
In most cases, this value does not need to be changed. The default
values of 800μs and 300μs for OSX/linux/other and Windows, respectively,
should be reasonable if you have an FTDI based SIO2PC-USB. If you
have an RS232 SIO2PC connected to a real serial port, you can probably
use a value closer to 300μs on linux/OSX/other than the default 800μs.
See issue #2 on github
for more information about why this discrepancy between the default
values exists.
Note: AtariSIO is available under Linux only!
After installing and running the AtariSIO module and making sure that
you have the required permissions, you just need to enter a device name
which should be /dev/atarisio0 under normal circumstances and select a
handshaking method as described above for the standard serial port
backend. Please refer to AtariSIO documentation on how to build and
install AtariSIO.
After making sure that you installed and configured AspeQt correctly,
you can start using it with your Atari. If you used similar software
before, it should be fairly straight forward.
The AspeQt 8bit Cartridge can be run from most Atari cart emulators (UnoCart, Ultimate cart, etc.)
All AspeQt disk and most printer functions can be done using the cartridge.
Two versions of the cart are available:
Cartridge directory path set in:
Tools -> Options -> Emulation -> "RCL Client local path"
Instead of using real disks, AspeQt uses disk images. These are regular
files that contain an image of an Atari disk. There are several formats,
the most common being the .atr format, currently AspeQt only supports
.atr, .xfd, atx, and .pro formats.
AspeQt emulates 15 disk drives. You have one slot for each of them,
labeled D1 through DO (letter O). D9 through DO are only supported by
SpartaDOS X and compatible DOS (see SDX manual for details on supported
disk drive identifiers). You can make AspeQt to show only the first
slot, the first 8 slots, or all 15 slots using options in DISK and
WINDOW menu items. \
+ To hide/show drives D9 through DO, use menu item Disk/Hide drives
D9-DO (CTRL+H),\
+ To toggle AspeQt mini mode use menu item Window/Toggle Mini Mode
(CTRL+M),in mini mode AspeQt shows only the first drive slot,\
+ To toggle shade mode in mini mode use menu item Window/Toggle
shade mode (CTRL+S), in shade mode AspeQt shows a semi-transparent
window which does not completely block the view of underlying UI
objects,\
Note that all drives are actually available for use with your Atari in
all AspeQt display modes whether they are visible or not.\
You can mount a disk image to an empty drive slot by
You can see the result of your operation in the log display which is
below the disk slots, if the operation is completed successfully, your
Atari should be able to see the mounted disk image just like a real disk
in a real drive.
You can use the tool buttons and context menu items to perform other
operations like saving the disk image, enabling write protection for the
image, reverting the image to its last saved state, ejecting
(unmounting) the image, creating a new image and so on. You can also
swap images using drag and drop.
Folder images provide a similar function to the features variously named
as “PC mirror’, “Simulated disk”, “Share point” etc. by other peripheral
emulators. This is basically a simulated Atari DOS2.5 disk. Instead of a
disk image, you can mount a folder in your PC that contains some Atari
files and Atari will see it as a disk with the same files in it.
Currently, the mounted folder will be seen as a standard DOS 2.5 disk
and it’s sequential access (Basic NOTE/POINT commands will not work as
expected) and read-only. Although Folder Images are simulated and
behave like Atari DOS 2.5, there are some differences. The most
important difference is that each file can be as large as 8MB in size
and file sizes are shown as number of bytes as opposed to number of
sectors (unlike Atari DOS). Maximum number of files in the directory is
64 and subdirectories are not supported. Folder Images are also
compatible with MyDOS, all versions of Spartados and SpartaDOS X. There
may be issues with others.
Folder images are also bootable as of version 0.8.5, but since the
folder image is a simulation of a standard DOS 2.5 disk, you can only
boot into a DOS that is compatible with AtariDOS disk structure. There
are two exceptions to this, first one is SpartaDOS, AspeQt will allow
you to boot into a 3.2G version of SpartaDOS but there are some
limitations. AspeQt will also allow you to boot into the standard
version of MyPicoDOS 4.05. See the following section for for details and
limitations:
To boot your Atari with a Folder Image, first mount a PC folder to disk
slot 1 (D1:). Once mounted, right-click on the Folder name and select
Folder Boot Options from the menu, select the DOS you would like the
boot and click Apply. make sure AspeQt is ready to receive commands
from your Atari and finally turn your Atari ON, selected DOS will be
booted. You must select a DOS boot option if you mounted a Folder Image
for the first time and you want to boot your Atari from that folder
whenever the folder is mounted. You normally only select the DOS option
once for each Folder Image. The Folder will remain bootable with the
same DOS between AspeQt sessions.
Warning: AspeQt will copy the necessary DOS files into the mounted
PC Folder to make it bootable. Do not keep any other DOS files (like
dos.sys, dup.sys etc..) on that folder as they will be erased/replaced.
Note that you don't need to supply any DOS files, AspeQt distribution
supplies the files necessary to boot your computer. These DOS files are
copyright of their respective owners, 13th Leaderand AspeQt distributes
those files with the understanding that they are either freeware,
abandonware or public domain and are widely available for download
through the internet. If you are the copyright holder of one or more of
these files, and believe that distribution of these files constitutes a
breach of your rights please contact The 13th
Leader. We respect the rights of copyright
holders and won't distribute copyrighted work without the rights
holder's consent.\
The following DOSes can be booted from a Folder Image:
MyPicoDOS 4.05 This game DOS is provided to support Folder
Images which hold Atari games. You can quickly boot and start your
games conveniently from a PC Folder. Only standard version of
MyPicoDOS is provided and supported. When selecting MyPicoDos as
your boot DOS there is an extra option on the menu to disable high
speed SIO code built into this DOS. If checked, this option will
instruct MyPicoDOS to run in normal speed. This may be necessary
under certain configurations. One example is if you are using an
Ultimate 1MB board or a PBI device like IDE Plus 2 on your Atari
with high-speed OS enabled. MyPicoDOS used in high-speed mode will
conflict with the high-speed OS on the Atari, so checking this
option and booting and running MyPicoDOS in normal speed will solve
this problem.\
AspeQt will also automatically generate a piconame.txt file
during the Folder Image boot process. So if you have game files with
long file names they will be displayed with their full names when
MyPicoDOS menu appears. piconame.txt file will only be
created/updated when you boot, so if you add more game files to your
PC folder during your MyPicoDOS session they will not show with long
names until you reboot.\
Boot files folder for MyPicoDOS is \$bootpic. it is not
recommended to modify this folder, unlike AtariDOS and MyDOS there
are no customizations you can make for MyPicoDOS.
- SpartaDOS 3.2G SpartaDOS is not compatible with AtariDOS. Its
disk/file structure and boot scheme is completely different. So this
DOS is only partly (and I would say rather crudely) supported. You
will be able to boot SpartaDOS version 3.2G from a Folder Image with
the following limitations:\
- To boot SpartaDOS from an AtariDOS structured Folder Image is an
impossible task. So AspeQt uses some (not so elegant)tricks to
coerce SpartaDOS into booting from an AtariDOS compatible Folder
Image by giving it the impression that it's booting from a
SpartaDOS formatted disk. Once the boot is completed AspeQt
forces SpartaDOS to re-detect the Folder Image as an AtariDOS
formatted disk so that it can display and manipulate the files
within the folder. The mechanics of this scheme necessarily
limits the boot proccess in the following ways:\
- You can not load drivers or run an autorun.bat file during
the boot process
- Once booted from, a Folder Image won't be bootable again
until you right-click on the Folder Image name, select
Folder Boot Options, select SpartaDOS 3.2G and click
Apply. This will reset the Folder Image boot files and
will make the folder bootable once again.
- You can not modify/delete files in the boot files folder
\$bootspa

Most Atari programs floating around on the internet come as Atari DOS
executables. These files may have .exe, .com, .xex or any other
extension. Instead of messing with disk image software and DOS, you may
directly run these files in your Atari using AspeQt.
You can either drag and drop a file with .exe, com or .xex extension
into any slot or you can use the menu item “File/Boot Atari executable”
to access this feature. A dialog with the necessary instructions will
pop up and the file will be loaded and run. You can leave the dialog
open to boot from the same executable more than once. A reload button is
provided which will reload the executable into memory. This button is
intended for atari software developers who may be developing on the PC
and testing their software after making changes to it. Reload button
will ensure the most recent executable is loaded from the PC, and as
such is mainly a convenience feature for such developers.
The executable booter has an optional high speed code which will allow
you to load programs a lot faster. You can enable/disable it with the
“Tools/Options/Emulation/Use high speed executable loader” check box.
The high speed code is not able to cope with higher speeds than divisor
3 so check your configuration before attempting to load a file in this
way.
Please note that this feature is not compatible with every executable
and, in practice, it’s not even possible to implement such a loader.
High speed loader has even more issues. So there will always be some
programs that you won’t be able to run with the executable booter but
hopefully the number of the compatibility problems will decrease with
future versions of AspeQt.
AspeQt can playback cassette images in .cas format. These are PC files
that contain data extracted from an Atari cassette. You can either drag
and drop a file with .cas extension into any slot or you can use the
menu item “File/Playback cassette image” to access this feature. A
dialog with the necessary instructions will pop up and the file will be
played back.
The cassette emulator can be configured to ignore the baud rate that is
embedded in the image file in favor of a custom one. This may speed up
the load times but can cause compatibility problems. You can
enable/disable it with the “Tools/Options/Emulation/Use custom baud rate
for cassette emulation” check box. When enabled, you can use the spin
box below to set the custom baud rate. The available values range from
425 through 875 bps. These values are the lowest and highest speeds that
the Atari OS can process. The normal speed is 600 bps.
The cassette emulation does not support rewinding or seeking in the
images. This may change in the future versions.
AspeQt emulates a generic text-only Atari printer. It only emulates the
first printer device, that is “P1:” You can view, save or print the
emulated printer output using the “File/View printer text output”.
Support for ASCII and ATASCII is provided.
AspeQt allows you to save and load your disk sessions, that is, the
order and names of the mounted images and their settings. You can access
this feature from the “File/Open session” and “File/Save session” menu
items. As of version 0.8.2 AspeQt fully implements multi session
capability. This means you can now launch multiple instances of AspeQt
using different session files and have different configurations for each
session. This makes possible serving more than one Atari computer from
one PC so long as you have more than one COM port and SIO2PC cable
available. Simply create different sessions with different settings and
save them to a permanent session file (a file with .respeqt file
extension).\
If you plan on serving more than one Atari computer simultaneously,
make sure that the PC is fast enough to handle similtaneous SIO requests
as Atari SIO is very time critical and can fail if the requests are not
serviced in a timely fashion. Experiment with the multi-session
capability and verify that it can be run reliably before you put it on
serious use.\
The following parameters can be configured for individual sessions
(stored in each session file)
The following configuration parameters are global and apply to all
sessions (stored in Windows registry)
The following configuration parameters apply when AspeQt is launched
without a session file (stored in Windows registry)
To launch a session, create a shortcut (Windows) or a link
(Unix/Linux) in a folder with the session file name as a command line
argument:\
An example of a shortcut for Windows would be:\
"C:\Program Files\AspeQt\AspeQt.exe" C:\Program
Files\AspeQt\session.AspeQt
The Disk Image can be created in the following capacities:
Example: ASPECL DNmyhd.atr.6 => will create and mount a quad density
harddisk .atr image with the name myhd\
And here's an example of invoking AspeCL with multiple command line
switches:\
ASPECL TF DS18 DMBASICXE.ATR => will set the date/time and turn TD
line OFF, will swap disks 1-8, and will mount basicxe.atr disk image to
the first available disk slot, returning back the slot number to Atari.
AspeCL is currently a command line based client which is fully
compatible with and runs only under SpartaDos (v2.5 and up) and
SpartaDos X versions. A separate menu driven client for menu based DOS
(like AtariDOS and MyDos versions) will be available in the future.
Some of the functionality in AspeCL also depend on the underlying DOSes
capabilities. For example setting the Date/Time from the PC is a DOS
dependent feature as it requires specific Date/Time drivers from the
DOS. Other functionality like mounting/unmounting/swapping disk or
folder images are DOS independent and therefore are available under
different DOSes.
AspeQt supports ApeTime (Date/Time downloader utility) from the
AtariMax APE package. The support code has been added back in from older
versions of AspeQt.
