AspeQt is a cross-platform, free and open source Atari 8-bit serial peripheral emulator. The name is an acronym for Atari serial peripheral emulator for Qt, Qt being the cross-platform application development framework used by AspeQt.

AspeQt emulates various Atari 8-bit peripherals like disk drives and printers via an SIO-2-PC cable. If you are familiar with software like Sio2Pc, APE, Atari810, AtariSIO etc., you probably won’t have any problems getting used to AspeQt.

Even though AspeQt is not fully mature yet, it is easy to use and, despite its shortcomings, has many features that you may find useful, the highlights being:

• Cross-platform GUI with drag and drop support.
• 8 emulated disk drives with support for 512 bytes per sector disk images.
• High speed operation up to 6 times faster than the normal speed.
• Ability to use PC folders as emulated disks.
• Disk image explorer for viewing and modifying disk image contents.
• Ability to run Atari executables without messing with disk images and DOSes.
• Printer emulation.
• Cassette image playback.

Changelog:

version 0.8
    + This version introduces the AspeQt client module AspeCl. AspeCl runs on the Atari computer and serves as a client to AspeQt. In this release only Date/Time functionality is implemented, in future releases more functionality will be added. (Ray Ataergin)

            AspeCl is fully compatible with SpartaDos and SDX, and support the following command line switches:

                    TS  => Set Date/Time on Atari
                    TO  => Set Date/Time on Atari and turn TD Line ON
                    TF  => Set Date/Time on Atari and turn TD Line OFF

                         usage:  AspeCl TS|TO|TF

      With the introduction of AspeCl the use of Apetime is now deprecated. AspeQt still supports Apetime as is with no further development to adapt to future releases of Apetime (Ray Ataergin)
    + MainWindow SIZE is now saved and restored (Ray Ataergin)
    + Added a “Strip Line Numbers” option when saving text printer output to a PC file.
      This will help ease the conversion of Atari based source programs printed through AspeQT for editing/compiling on a PC based IDE/Compiler (Ray Ataergin)
    + Reorganized About Dialog content (Ray Ataergin)
    + MainWindow POSITION is now saved and restored (Ray Ataergin)
    + Created and added an application icon, modified main window to use the new icon (Ray Ataergin).
