## !!!HELP NEEDED!!!
|
|
|
|
Thanx a lot for all positive comments i read here and there, but i definitively need contributors & testers.
|
|
|
|
Anybody wants to join this project ?
|
|
|
|
If you're interested on contributing, please send a message with your skills and in which area you are interested to work on (Network, Kernel, device drivers for additional hardware support, GUI, graphical resourses, command line tools....)
|
|
|
|
This is some sort of "last hope call", some of you were right, this project is really huge!!!
|
|
Anyway, i'm convinced that a small team of developers could reach "version 1.0" with GUI & network support in few months....i'm working on it for...4 years now, spending the most of my free time fixing hardware to test this code instead of...writing it!
|
|
|
|
Well, let me know if you can bring "fresh blood" to this stuff...
|
|
|
|
## 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 additional hardware. As VBL signal is NOT available as an IRQ on //e (it is on //c & IIgs)
|
|
it makes preemptive multitasking impossible.
|
|
|
|
__A new attempt using Mouse card VBL IRQ is targeted in 0.9.1.__
|
|
|
|
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.
|
|
+ TCP/IP stack
|
|
+ AppleTalk Support
|
|
+ GUI & Printing
|
|
+ Archive, Disk Image transfer tools (ADT client!)...
|
|
+ Question : Pascal or C Compiler?
|
|
+ --> Answer : C compiler....Next version of Kernel API will be closer to STDLIBC, Genralize the use of C-Strings
|
|
+ ...sure there is some more!

## General Information:
|
|
|
|
Kernel API 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.
