# A2osX (0.9)
|
|
Multi-Tasking OS for Apple II
|
|
|
|
## Requires :
|
|
Enhanced IIe (65c02 cpu) with 128k, //c, IIgs
|
|
## Introduction...
|
|
A2osX is a cooperative, event-driven multitasking kernel (meaning it is applications that are responsible to give back control to kernel)
|
|
Its principal goal is to collect all "genius" 65c02 pieces of code ever written here and there, concentrated in the same environment.
|
|
(including IP Stack & HTTPD/TELNETD..., GUI & graphical tools...)
|
|
"Complete working place", no needing any more to reboot to switch between tons of diskettes!!!
|
|
|
|
A2osX is designed to work on any "stock" 128k Apple //e with no hardware modification. As VBL signal is NOT available as an IRQ on //e (it is on //c & IIgs)
|
|
it makes preemptive multitasking impossible.
|
|
(Well, GSosX, 16 bits equivalent for IIgs, another project which is "cooking" in my mind, could do it!)
|
|
Kernel, loading in Aux LC on top of ProDOS provide API inspired from Linux/Unix World to allow writing applications & command line tools on top of it.
|
|
This kernel provides an advanced "Memory Manager" able to relocate 65c02 code.
|
|
"Event Manager" makes TCPIP stack able to listen on several ports, manage ARP,DNS...cache expiration and any background processes.
|
|
"Task Manager" is responsible to "distribute" CPU time to several loaded processes.
|
|
"Device Manager" handles event collected from builtin devices as well as devices added by loadable drivers.
|
|
|
|
If you're 65c02 or Z80 code writer, how to contribute ?
|
|
|
|
Several subprojects are now indentified :
|
|
|
|
+ Hardware Support : adding drivers to support more & more hardware (RAM cards, storage....)
|
|
+ Z80 support : Kernel could pass control to any Z80 detected on the system.
|
|
+ TCPIP stack : TCP still missing!
|
|
+ AppleTalk Support
|
|
+ GUI & Printing
|
|
+ Archive, Disk Image transfer tools (ADT client!)...
|
|
+ Question : Pascal or C Compiler?
|
|
+ ...sure there is some more!

## General Information:
|
|
|
|
** Kernel 0.9 complete rewrite in progress **
|
|
|
|
(Kernel 0.8 has been archived)
|
|
It is confined in Aux LC Bank 1 & 2 to leave enough room at $EOOO for Drivers.
|
|
Network drivers, Mouse, DHGR.DRV can load and fit in Aux LC.
|
|
Now it's time to make all external BINs use new API, then GUI development will resume.
|
|
|
|
**A2OSX.BOOT.po** : 140k BOOT disk image with all binaries
|
|
**A2OSX.DEV.po** : 140k disk image with ASM binaries, Debug Tools & INClude files
|
|
**A2OSX.SRC.po** : 800k S-C MASM boot disk image with all sources
|
|
|
|
OApple+1,OApple+2,OApple+3 to switch between screens : Kernel Log, text, DHGR.
|
