Z80 işlemcili makinaların günümüz şartlarında tekrar ayağa kalktığını görmek isteyenler için alternatif(aslında alternatifsiz) işletim sistemi projesinin 2.0 sürümü duyuruldu.
Detaylı bilgi için tıklayın Bu sürümle beraber gelen yenilikler:
Release 2.0 [30.08.2007]
Operating system (general)
* 1024KB support: The available address space has been doubled to 20bit. SymbOS supports now up to 1 Megabyte RAM memory on all computer platforms. Code and data will be stored dynamically at any free place without the need to modify existing applications.
* Amstrad PCW/Joyce port: SymbOS has been completely ported to the Amstrad PCW (Joyce), which is now the third supported system. The full screen resolution of 720x256 can be used in SymbOS. All models like the PCW8xxx, the PCW/PcW9xxx and the PcW10 are able to run SymbOS.
* PCW 180KB disc format: Single side Amstrad PCW/Joyce floppy discs with a total capacity of 180KB can be accessed in SymbOS, too. Of course they are now also read- and writeable on the CPC and the MSX platform.
* 24 applications at the same time: To be able to use the full 1024KB ram, the number of possible applications running at the same time has been increased from 16 to 24.
* SymbOS extensions: On computers with enough memory you can load the optional SymbOS extension module. This module extends the operating system with additional functions like the "Security" dialogue and password protection.
* Miscellaneous: Any application can specify the minimum required SymbOS version, and the operating system will prevent the execution of applications developed for a newer SymbOS version. To provide the smooth processing of system functions like mass storage device access, its task priority has been increased and has the same level like the Desktop Manager. This was necessary since the existance of MP3 playback in SymAmp. The memory reservation proceeding has been optimized, when an application is loaded.
Desktop Manager (Graphical user interface)
* Richtext support and 16 colour controls: The desktop manager now includes a multifont- and control code-based richtext output functionality. Beside graphic controls there are now additional ones with 16 colour support.
* Direct click handling for background windows: If the user clicks on a window, which is not in the focus position, it will not only pop up, but also directly react on the click.
* No needless scrollbars: Resizeable windows, which doesn't require scroll bars, won't show them anymore. This enhanced the overview in applications like SymCommander etc.
* And more features: New single-element update command for control collections, windows can be opened at the centered position, resize and scroll event messages, function for detecting the screen resolution.
System manager
* Shared services: SymbOS supports the handling of shared services. These are processes, which run in the background and provide their functions like the access to external hardware and other things to multiple applications at the same time. SymbOS will start and quit them automatically depending on the fact, if they are actually needed by one or more applications or not.
* Application finder: Every application can be found via its ID string by any other application. As an example this makes it possible to communicate between two applications or to prevent the execution of two instances of the same application.
* New confirm and alert windows: The infobox feature has been extended and now handles multiple buttons and response messages on user clicks.
* Enhanced file selector dialogue: As the old way was confusing the users too much, the file selector dialogue now provides a special directory selection mode. With a second option you can switch between the "Open" and the "Save" mode.
Platform specific
* CPC: The speed of the Mode 2 (640x200x2) graphic routines have been increased a lot. Working in Mode 2 is now nearly as fast as working in Mode 1. Mode 0 was never useful and has been removed to free memory space for new functions. By setting the preemptive taskswitch frequency to the usual 50Hz there is 5% additional free CPU time available now.
* MSX: The FDC drivers for all Philips, Sony and a lot of more computers have been completely debugged and seem to run without problems now (thanx to Alex Wulms for additional hints!). SymbOS now can boot MSX Basic directly (thanx to NYYRIKKI, who wrote the boot routine!).
* PCW: SymbOS supports the AMX and Kempston mouse of the Amstrad PCW/Joyce.
Applications
* SymZilla: A preview of the new richtext viewer and internet browser SymZilla is availabe.
* SymAmp supports MP3 and PT3: The SymAmp music player does now also support the two new music formats MP3 and PT3. MP3 is the most popular format for digitized music, while PT3 is the most powerful and widespreaded AY format ever for the ZX Spectrum and other platforms.
* New SymShell control codes: To be able to provide terminal emulation for VT52, ANSI, VT100 and more in Telnet-like applications, SymShell has been extended with several new powerful control codes.
* Control Panel: The Control Panel provides Amstrad PCW specific settings and prevents double-execution of itself.
Bug fixing
* Mouse wheel: If you use the mouse wheel above a list object, which doesn't include a scroll bar, there won't appear a wrong scroll bar anymore. This bug appeared in the songlist of SymAmp in the past.
* Timer messages: Because of ID conflicts it wasn't possible to send to and receive messages from timers.
* Icon dragging : Picking and moving icons was not possible, if another application updated its window at the same time.
* More bug fixes: A lot of additional bugs have been fixed as usual.
