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:

• Up to 15 disk drive emulation.
• Up to 6x SIO speed (125,000bps)
• Support for ATR, XFD, PRO and ATX (preliminary) disk images.
• Mount folders as emulated disks.
• Disk image explorer.
• Directly boot Atari executables.
• Text only printer emulation with PC print, save, and ATASCII font support.
• Cassette image playback.
• Multilingual GUI (English, Polish, Slovak, German, Turkish and Russian)
• AspeQt client module (AspeCl) for Atari, communicates with the server and performs a variety of remote operations.

Changelog:

• Updated the English language manual.
• Minor re-grouping of drive slot buttons.
• Added directory print capability to image explorer window (Ray Ataergin)
• Added boot capability from a Folder Image. Simply copy the DOS.SYS and DUP.SYS files from a DOS diskette to a PC Folder, mount the PC folder to drive slot#:1 as a Folder Image and boot your Atari. Currently only Atari DOS has a built-in support. MyDos will be supported on the next release. (Ray Ataergin)
• Dropped ApeTime support from AspeQt. AspeCL is now the only supported Time/Date client
• Remote Control software for AspeQt (see AspeQt documentation for more info) (Ray Ataergin)
• Implemented auto-commit remote toggle capability to AspeCL, it was previously documented as “in development feature” (Ray Ataergin)
• Implemented remote image file creating/mounting capability to AspeCL, it was previously documented as “in development feature” (Ray Ataergin)
• Implemented remote image file mounting capability to AspeCL, it was previously documented  as “in development feature” (Ray Ataergin)
• Tested and fixed AspeCL client SpartaDos X date/time handling (this was not previously tested as I did not have SDX back then) (Ray Ataergin)
• Updated AspeCL client code to accomodate SDX drives 9-15 (Ray Ataergin)
• Updated AspeCL server code in AspeQt to accomodate SDX drives 9-15 (Ray Ataergin)
